* VISUALLY EXPLAINED
In this uniquely explained video I explain whether or not you can use car engine oil in a lawnmower.
Oregon SAE30 Lawnmower Engine oil is a very good quality oil at a very reasonable price, and I have used this on many occasion, Find it here: amzn.to/37B288p
Using car engine oil in a lawnmower is a topic that often piques the curiosity of many homeowners who wonder whether they can use the same oil for both their vehicle and their lawnmower. While it might seem like a convenient idea, there are crucial differences between car engine oil and lawnmower oil that need to be addressed.
1. Viscosity and Additives: Car engine oil is designed to work under high-temperature, high-stress conditions in a vehicle's engine. It typically contains additives that help with cleaning, reducing friction, and handling high heat. On the other hand, lawnmower engines operate at lower temperatures and have simpler lubrication needs. Using car oil in a lawnmower may not provide the right viscosity for effective lubrication, potentially leading to engine damage.
2. Oil Change Intervals: Lawnmowers usually require more frequent oil changes compared to cars because they often operate in dusty environments and are used seasonally. Car engine oil, formulated for longer oil change intervals, may not be suitable for a lawnmower that requires more regular oil changes.
3. SAE Rating: Car engine oils carry an SAE (Society of Automotive Engineers) rating that indicates their viscosity at high and low temperatures. Using an oil with a higher SAE rating meant for a car in a lawnmower may lead to poor engine performance or damage.
4. Lawnmower-Specific Oils: Manufacturers often recommend or sell specific oils for their lawnmower engines. These oils are designed to meet the requirements of smaller, air-cooled engines with simpler lubrication needs. It's usually best to use these recommended oils to ensure optimal lawnmower performance and longevity.
In conclusion, while it might seem tempting to use car engine oil in a lawnmower for convenience, it's not advisable due to differences in viscosity, additives, and maintenance needs. It's generally best to use the oil recommended by the lawnmower manufacturer to ensure proper lubrication and prevent any damage or performance issues.

Most push mowers sold today in the US recommend a multigrade 10w/30. Mowers of many years ago often used a straight weight sae 30 weight oil that was low foam formula because it is usually a splash lubrication system. Most mower oil will say low foam 10w/30 small engine oil.

@TheRepairSpecialist 3 года назад

@BlackhawkPilot 3 года назад

A very good explanation based on oil grade. However, grade is not the issue, film strength is. Since I switched to M1 full (base stock 5) synthetic oil I have never had an oil related engine failure, auto or small air cooled single cylinder. Small air cooled engine temperatures rise dramatically when they lug down and work hard with less air flow because of lower RPM (a thermal gun reading on the head can show a 200 degree rise), e.g. my wood chipper branch after branch or my rototiller workin for hours with little letup, this is where film strength rules and synthetics are much better. Because of its far superior film strength and I use my equipment hard I use M1 0W 40.

If the engine uses less fuel to do the same work, it is usually a good thing. So for the break in did use a single grade,. When it was time to replace it. Had some left over 5W30. Immediately noticed it used less fuel. less fuel means less heat. Used 10W 40 in a 600cc sport cycle. It was not recommended. At 70,000 miles started looking into rebuilding it. But the big problem was could not get a shop to work on it for tuning and general maintenance when it hit 50,000. Still had the original clutches in it. Oh and when it was 120F (48C) I still rode it. I also still wore leathers with a water soaked sweatshirt under it. Works like a swamp cooler. Friction and heat are not combustion engine friends

I use Mobil 1 15w40 Syn Delvac Oil for diesel engines in all my small engines, more protection than any other oil on the planet. Big diesel turbo engines run long and hard, in extreme heat and conditions, and the additives in this oil allows them to do it. Get it in gallon jugs at Walmart, priced about the same as other Mobile one Synthetic Oils (In 5 quart jugs), And be done with it. Far superior to other car engine oils, it meets and exceeds!

@dietermeyer9231 Год назад

A manual will state that you shall use oil according to ambient temperature. My mower can handle SAE 10W to 40 (single) and 10W30 to 20W50 (multi). It all depends on ambient temperature. A 10w30 works from -20 degrees C and up to 32 degrees C. A 10w40 works from -20 degrees C and to above 40 degrees C. In hot areas I would go for a 10W40, 20W40 or a 20w50. A single 30 will work from 10 degrees C to 32 degrees C and a 40 will work from 25 degrees C to above 40 degrees C.

@martinschulz9381 3 года назад

There are variables here. Air cooled engines tend to run hotter than liquid and straight 30 weight won't thin out like multi weight. In warmer temp areas 30 weight is better. In moderate temp areas 10W30 is fine. Small engine oil has different API classifications and generally has more zinc anti wear additive among other things than auto oil. Small engine oil is readily available every in hardware or home store. Why not just use what you're suppose to?

Very good explanation on oil for the small engine, though most failures on small engine are not due to incorrect oil but lack of oil!, a lot of people seem to think these engines do not need any maintenance and just run forever without attention, if it fails, then off to the big box store for another lawn mower, they think putting fuel in it is all it needs.

@surg9029 Год назад

I worked my way through college as a mechanic on a golf course working on everything from small engines to bulldozers. The greens mowers used 16hp Kohler engines lubricated by splash from a dipper on the end of the connecting rod, and they worked hard and ran hot. The recommended oil was 10w30 and I would get about 800 hours service. Changing to straight 30 oil for diesels extended the life to 1600-1800 hours.

Do small engines experience wear mostly on starting? If yes, then wouldn't a lower viscosity cold rating (the first number in a multi-viscosity oil) be preferred to single-weight oil because the small engine could theoretically last longer. Here in the USA, 5w-30 oil is often less expensive than a 30-weight oil because multi-weight oil goes on sale on Amazon so often.

I have ride on tractor mowers and it has been said to use oils with detergents, high zinc and phosphorus for better wear protection. Some have even resorted to using diesel oils which have all these properties. if I use a diesel formulation 5W-30 would this then be the ultimate oil to use ? The engines I have are both Kohler engines. One is a Command 17.5 Hp and the other is a 25Hp Courage (SV-730). My Courage engine recently found with one bent pushrod. Not sure why. Am Still waiting for new parts to arrive and then do a full investigation.

@kd5byb 4 года назад

Absolutely correct and another great explanation! (I'm a mechanical engineer with some background in tribology.) I've subscribed. Some folks say that car oils may have too low of a zinc content for small engines, but one also must consider that small engine valve spring tension isn't all that high, so the force of the tappets on the camshaft is no where near what it is in an flat-tappet automobile engine...so car-levels of zinc should be fine...and my 23 year old Kohler CV12.5 in my Deere lawn mower agrees! :) Can't believe with such high-quality content you're only at 45k subscribers.

@vincentrobinette1507 3 года назад

I've always used 10W-40 in my older engines, and 10W30 in my newer engines. I just look for the "SN" API classification, because air cooled engines tend to get hotter than liquid cooled engines, particularly when ran at or near full load. I don't bother with the expensive synthetic or other premium oil, since it has to be changed too often to take advantage of the better sheer viscosity breakdown or thermal breakdown properties of the better oils. These engines have no oil filter, and will contaminate the oil, no matter how good it is.

@MrSGL21 3 года назад

i would have agreed with you 4 months ago but not now. i bought a used snapper rer with a 12.5 briggs intek. someone had changed the oil before i bought it and i didn't realize it was fresh oil when i drained it. i replaced that oil, which i'm positive was sae 30, with 10w30 amsoil small engine oil. that was back the middle of May. i've been mowing every week since then except for a couple of times i went two weeks, but that just means i had to mow slower and the engine worked harder and longer, and i shit you not, no lie, the oil has not changed color AT ALL. i mean its clear. i just assembled a woodchipper this evening from amazon and when i filled its crank case i used the left over oil and put it in the snapper. i checked the snapper and the oil was still clear. i've got atleast 10 hours on that oil. its clear. its barely amber and looked like it came out of the bottle. usually oil starts browning immediately especially in a small air cooled engine. not this one. i dunno if its this motor or if its the oil. i'll find out eventually but i'll be dammed this oil is not breaking down at all.

@turboslag 3 года назад

I don't think the mutigrade viscosity explanation is quite correct. Taking your example, 5w30, 5w refers to the viscosity at 0 degrees C, as in , freezing point of water. 30 is the viscosity at 100 degrees C. And the oil doesn't become thicker at high temperature, it just reaches a comparitive viscosity to that when it is cold. Actually, the main reason that 30 grade oil is advised for use in small horticultural engines is historic. Typically, many decades ago, the types of engine in question had no or very little in the way of oil filters. So, the oils used had no detergency. This allowed combustion deposits and particulates to settle out and sit at the bottom of the crankcase when the engine was not in use. Then, when operation was resumed the lack of detergency in the oil would leave the deposits undisturbed and not circulate in the oil, thus causing accelerated wear etc. The problem that could then occur is if the oil used changed to a detergent multigrade later in that engines life, this would cause the deposits to be diluted and carried into circulation, which cause wear and sludge formation in the engine. So, now we are in the modern era of high performance lubricants, there is no reason not to use multigrades in small engines, as long as they are run from new on such oils, thus allowing the oil to do its job. In fact, modern multigrades will be much superior to old spec single grade 30 and give the engine much longer working life. I have a Honda HR 194 mower, which is now in it's 4th decade, this has run on 10w40 since I bought it new all those years ago and is still in perfect running order. Starts as soon as the rope is pulled, no smoke, no excessive engine noise, no oil consumption. I just change the oil at the start of the season and it just keeps going. And the owners manual does specify the use of multigrades, with a chart according to prevailing temperature.

My briggs and stratton manual from 2002 (this is a twin opposed motor) says under 40deg F, do not use SAE 30, but 5W30, synthetic preferred. Says engine damage could happen

@davidleatherneck Год назад

Hmmm. Well, now take into consideration the extra cooling/lubricating needed for AIR COOLED Engines like Motorcycles and V Twin mowers. There is a reason Kolar, Kawasaki, Brigs and others have specialty Oils for Air Cooled engines. A car/truck has a water filled radiator to cool the engine. Mowers and Scooters have no water filled radiator, with the exception of a couple. Special formulated Oils are required for air cooled engines. Regular oils get way too hot. If you want the warrantee to be good, use the correct oil. Thanks.

If your lawn mower doesn't have an oil filter you need to put non-detergent oil in it if you don't it's going to clean your mower motor and all that junk that's collected on the side of the walls is going to be run through your bearings?

@armadillotoe Год назад

I have an OLD lawnmower. I used synthetic 10w30 in it for the last few years. I have noticed I have more old seeping through the gaskets than with 30w conventional oil. I believe the synthetic oil cleaned everything better and exposed micro leaks in the old gaskets.

With small engines, there is no oil filter, so Non Detergent oil is used as it allows the soot and particles to fall to the bottom vs automobile engine which has a paper filter so Detergent Multi grade is used to keep the soot and particles in suspension and be trapped in the filter media I have seen equipment still running okay with the wrong lubricant and even chemicals that were not oil. Something slippery.

In my area (suburban USA) a quart of Walmart multi-grade car oil is cheaper than Briggs and Stratton or Kohler mower oil. In fact the mower oils are usually pints not quarts. I have always wondered if the multi grade oil is too viscous and splashes too much to get to the passage ways in the small engines

@M3rVsT4H 2 года назад

Just thought I'd share, Downunder where the price gouging is real. For my whole adult life "Mower" oil has been a specialty product. And so by way of it's lower shelf profile and the economies of scale, it can routinely cost 4x that of any 30 weight multigrade on special at your local discount auto place. So a lot of Aussies use cheap car oil in small engines against the insistent advice of people who sell boutique single grade oil for outrageous prices.

@DJHITMAN29 4 года назад

Hello! First of all I'd like to say that watching this video gave me a much better understanding about how oils work and why there are different numbers on each container. The viscosity change information was invaluable! What I'd like to ask, is if my Amsoil 10W-30 Full Synthetic MOTORCYCLE OIL will work in my push mowers. One is powered by a 223cc Briggs & Stratton and the other is powered by a 160cc Honda. The container states that this is a High performance engine and transmission lubricant. There are of course API and GL numbers on the back. Not sure if you need that information to answer my question. I've wanted to go to a synthetic from the regular SAE30 since I bought the mowers but want to make sure I do not do any damage to my engines. Amsoil does of course make a 10W-30 100% Synthetic oil specifically designated for small engines but will it make a difference? I have 5 or 6 quarts of the motorcycle oil on hand which is another reason I'm asking. Thank you very much for your time and your informative content! Ken aka The Lawn Ninja! ;)

I use a straight SAE 30 wt in my Briggs 6HP Toro walkbehind. It's about 25 years old. Bought it recently and gave it an extensive service. Changed the oil 2X immediately with a few oz of Marvel Mystery Oil. I found that the MMO helped it run smoother and also helped clean the accumulated crud out of the engine. Use 10W30 in my Honda GCV 160 with a splash of MMO. Snagged this Craftsman off a tree lawn last Fall and serviced it. Runs very smooth and always starts on the first pull.

Since synthetic is taking over and costs and arm and a leg, conventional 30 w oil is becoming scarce. I decided to simply use Delo 30 w for diesel engines as it is so much less money! What the difference, well diesel oil has more surfactants and higher quality lube properties, so why not?

@TheRepairSpecialist 4 месяца назад

HI thank you for sharing your thoughts and experience with using Delo 30W diesel engine oil in your vehicle! You've made an interesting choice by opting for Delo 30W diesel oil due to its affordability and purported higher quality lubricating properties. It's true that diesel engine oils often contain robust additives and detergents designed to handle the demands of diesel engines, which can translate well for certain applications in gasoline engines. While using diesel engine oil like Delo 30W may offer adequate lubrication and protection, it's important to consider a few key differences. Diesel engine oils are formulated to handle higher operating temperatures and stress levels typically found in diesel engines. Gasoline engines, on the other hand, may have different requirements in terms of viscosity and additive packages. When selecting engine oil, it's crucial to refer to your vehicle's manufacturer recommendations for the specific viscosity and type of oil suitable for your engine. Using the right oil can help optimize engine performance, protect vital components, and extend the engine's lifespan. That being said, I appreciate you sharing your approach and the reasoning behind your choice. It's always fascinating to explore different options and their potential benefits. Thank you for being part of our community and contributing to the discussion! Best regards, Craig

@solarsynapse 4 года назад

Use the oil that your particular engine requires unless money is of no concern. You left out a critical spec and that is ZDDP content. Newer vehicle engine oils do not have enough for flat tappet engines. Air cooled small engine oil, certain racing oils, most diesel oil and ATV/Motorcycle oil have an API rating of "J" which has the proper content of ZDDP. Look on the back of the containers. Briggs, Walmart small engine oil, Rotella T4, Honda GN4, Yamalube, Elf for certain VW diesels, etc. If you use an oil that has an API rating higher than "J" in the older designs, you will shorten the engine life. Some of the expensive Honda type engines have roller cams and oil pumps that use the newer oils. There is ZDDP additive, but too much is also bad due to corrosion.
