Is Costco's Kirkland Motor Oil Safe for Your Car? Let's find out! SuperTech Synthetic vs Kirkland 

Thanks to everyone who recommended comparing these 2 brands. Products Tested In This Video (in no particular order): Kirkland Signature 5W-30 Motor Oil: amzn.to/2E5Tzd1 Super Tech 5W-30: www.walmart.com/ip/Super-Tech-Full-Synthetic-SAE-5W-30-Motor-Oil-5-Quarts/17133942

The hardest working man on youtube

Since most major sports events postponed or cancelled, this has been the most exciting thing in sports term that I have watched

The most unquestionable and consistent youtube channel of all time.

Gosh the amount of time project farm puts into his meticulous testing is undeniably amazing and thorough, won't be shocked to see his channel be up to 6 million subscribers the next couple years how can you not wach this valuable content and have such an awesome education by doing so.

He replies to practically everyone and is so thorough in his testing. This man deserves much more subscribers and views

Don't forget the $1.50 Hot Dog & Soda.

Kirkland heavy-duty motor oil is made and blended by Warren distribution, the same company that manufactures Walmart's Super Tech brand. Warren distribution also has its brand of motor oil known as Mag 1 oil. In addition, Warren distribution blends motor oils for Meijer and AmazonBasic oils.

What a thorough and excellent comparison for two brands that many of us use often! Incredibly relevant information and much appreciated!

"we're gonna test that" must send a shiver down the spines of some companies lol. Great work.

*"We're gonna test that."* That could be the official Project Farm slogan.

Your attention to detail and effort planning these reviews is amazing

An excellent set of tests if I may say so. Great video. I commented before, on a previous engine oil related video, that there are standard tests which provide insight to the characteristics of oil performance. This suite of cold temperature flow, heat resistance, lubricity, and wear resistance are part of the industry test regime, and the lab tests you asked for are best-in-class when it comes to assessing the performance of lubricants. Dexos 2 approvals should provide consistency of formulation if both products claim they are compliant, and your tests certainly confirmed that both of these products were comparable. One issue of concern when buying engine oil is whether you can truly rely on the label; has the vendor really achieved the claimed approvals? If you buy from a reputable supplier this will not be in doubt but some disreputable businesses will use the Dexos 2 logo despite not having it i.e. not using the correct formulation, and sometimes make outrageous claims such as an engine oil being suitable for gasoline and diesel engines, motorcycles, and heavy machinery. Such products do not exist. Best to buy from a well-known or trusted supplier. Your tests conclusively proved that the Kirkland 5w-30 product is within specification and therefore represents great value for money. Thanks for doing such a great job.

This man pulls out all the stops for his videos and I appreciate the hell out of them

"we're gonna test that" Project Farm putting the fear of God into marketing teams across the world!

He sure puts these products through the mill in his testing, much appreciated and very cool channel, helping out consumers

I use many Project Farm videos in my auto shop class . The students really respond well to them. Thank You very much Sir!

Mrs. Farm must fear for her life every morning when she makes a cup of coffee. "Will this be the day he forgot to change the pot?"

Literally Anything: Project Farm: We're going to test that

Simply the best non-sponsor independent test ever done! Thank you!

One of the best resources here on youtube. Bravo Project Farm 👏 have made several well informed purchases after watching this channel. Thank you. AND ad free 🤯

I'm an avid motorcycle rider, and in our community synthetic oil can be $20 per quart. So many riders use Shell Rotella T6 from Walmart for $22 per 4 quarts because it's JASO MA rated (safe for motorcycle clutches). For the past several years, there have been so many forum wars about why you should or shouldn't use this oil vs the designer oils that cost 4x as much. There are now NO serious reviews that put this argument to bed once and for all. Would be awesome to see it. I'm sure all the motorcycle forums across the country would refer to the review.

I've never been so hyped watching cold oil slide down ramps.

Love the comparisons, please keep them coming. I recommend your channel to everyone

Your testing methodology and execution is so incredibly impressive!! Thanks so much for this fantastic comparison. Def earned my sub

Even though I don't have access to a Costco and suspected it was the same as Supertech and Amazon Basics, I still couldn't wait to watch the video. Simply because it's Project Farm and it's a new video.

Everyone is freaking out about the Coronavirus and we are just watching another one of Project Farms Great Video.

Wow! Fantastic video with more info than I've seen in purebred. I just paid $43.99 for a gallon of Mobil one at Costco. Their Kirkland beans is $30. After seeing all the testing done on this video, I'm returning the Mobil one tomorrow and grabbing the Kirkland. Thank you for the thorough study!

2 years ago based on your testing I went to Kirkland 0-20 and 5-20 oils in my high mileage 2010 Sequoia and not so high miles 2013 Tundra. I am totally sold on the Kirkland oils. I have switched to Kirkland for all of my vehicles. Your testing was the tipping point for me and I want to thank you for such a good process.

“We’re gonna test that” *Companies sweating nervously*

Something tells me you’re a “ get up at 4 am kinda guy”. High energy.

It’s great seeing you get even better with your videos over the last few years. I can’t wait to see how you’ll get even better

Regardless of what you're testing or if I watch it all, I always give a thumbs up to help your channel. I hope you'll keep doing what you're doing and always stay true.

Good to know, thank you! Confirms what my dad told me: "As long as it's SAE/dexos approved, most companies rely on marketing to fool you into thinking their oil is "better". THE biggest way to make your engine last is to change your oil at its scheduled mileage/time interval."

Todd....I have to admit to this fact.. You truly are my hero! I have NEVER seen such an unbiased and honest man!

Thanks for the hard work comparing and analyzing the oils. Gives me peace of mind knowing the Kirkland oil is as good as any of the other expensive brands.

Like many other comments beforehand, this is the type of information that is actually useful. Great video.

Click, like, watch, repeat. Best, most unbiased channel on RU-vid! Stay safe during all this madness, Todd.

I have a video idea. I'm always getting grease, gas, oil on my clothes. How about testing different brands of detergent. Help find the best value for removing the stains.

Your videos are usually the right length and pack in relevant info without the babbling that other people insert. Sub very well deserved.

It's amazing how you have so much time to do this. Amazing!

At that price, this must be a “loss leader” for Costco. Get you in for the oil and hope you buy groceries and a few mega roll packs of TP

And this ladies and gentlemen is how RU-vid should be used - thank you for posting a constructive and educational video - I am officially subscribed - keep up the good work

As always your research, data and results are very interesting and definitely helps to decide on products to purchase! Thank you for what you do!

Thank you for performing and publishing this test. I had seen analysis suggesting these are as good as any brand name oils, but yours is more rea-world combined with the lab tests.

As a new homeowner, I've based SO MANY purchases on your results, and not one of them has steered me wrong.

I was at Costco’s. Saw this oil. I said maybe this is too low of a price. I looked in the box, I lifted it up, checked the certificates, checked the prices again. I said I better do some research first. Thank you for the video.

The best YT comparison video of anything at all ever!!! Hands down! You are doing a great job thank you very much.

I am in awe of you! Followed you for years. Amazed at the thoroughness of your reviews. (I' m a retired scientist.) I wonder your background. Very scientific approach yet very practical and technical ('engineer like') process. EXTREMELY GOOD JOB!!! Keep up the good work!

As my dad used to say, "If it wasn't good Kirkland wouldn't put his signature on it."

Woo! Nothing better than Project Farm for those under quarantine. Keep up the good work man!

better than consumer reports...serious analysis and time to make that video! well done.

I'm glad to see this, as I just bought Kirkland synthetic oil for three of our vehicles in 0W-20 and 5W-20 viscosity. It does take a couple years to get anywhere close to 4000 miles on each vehicle but feel confident that waiting that long will not be detrimental to the engines. Side note: I've used Mobil one for many years.

Oil? *Were gonna test that.* Would love to see a “we’re gonna test that” tshirt... I would buy one!

Lol, i remember when it first came out, was like, I'll wait for project farm and then decide, thank you for all your hard work!

I enjoy your thoughtful and very well done analysis. This should be required watching for students to learn logic and test methods. When learning is fun, this is the end result.

I think it’s great that you tested and expensive oils. I really need to know if the expensive oils are worth the extra money compared to the discount synthetic oils like Kirkland. It would be great if you added mobile one or whoever you consider to be the top oil tested to see the comparison between those. Keep up the great work. I anticipate your next video

I may not be wiping my ass for the next two weeks, but now I can rest assured that my engine is protected, and my trip to Costco was not in vain, even though they ran out of toilet paper.

Here’s a video idea! “Which wall stud finder is the best?”

Thanks for the video! I have been using SuperTech full synthetic in all 5 of my Toyotas for about 4 years now. Thanks to your expert research, I continue to trust it.

My favorite channel! I lived inCali for almost 20yrs but I left the country for fam reason. Now I'm living in Manila and I still watch all PF videos. I wish we have kriks oil here. Shell and CalTax "which is Chevron" cost about $8 a liter. Love the channel all the way!

As someone who has watched since the first episodes, I love seeing how you've updated your equipment and processes to get more scientific and accurate results. Great job man.

Kirkland signature never ceases to amaze me with the quality of their brands products.

I enjoy your channel immensely... you are fair and being independent is definitely a plus....I am sure it can be costly to do some of these tests but the more the videos are seen and shared the more you get from you tube and I am part of a large community of car/truck guys and I am also a performance truck builder/custom/engine swap so I send and share all your videos 👍👌 keep up the great videos and comparison shopping

This is an excellent video! I have never seen oil filter openning check for metal bits before, thanks for showing it.

Just dropping a line to let you know what an absolutely fantastic channel this is. Since discovering the FARM I have not only enjoyed the content, saved money, bought the best bang for buck products, been educated AND provided with tips that saved me hassle and stress. Just flipping awesome. And I've made my working from home colleagues aware of you. Please keep yourself precautioned re this virus scourge. And everyone else.

The cooked oil in the coffee pots Look like the cooked coffee at Speedway gas stations.

Use the Kirkland 5W30 SYN in my Acadia, Canyon, and 200k mile Suburban for years. Never had any issues at all and much cheaper than big brands. Changed every 3k miles religiously regardless of what manual says and motors are spotless inside. 5.3 in Suburban looks brand new inside when you pull valve covers off.

I can't thank you enough for all your hard work Wtg with out help from companies

If I remember correctly Warren also makes the Supertech oil, so they're likely the same oil. Warren makes oil for a LOT of different brands, though that doesn't mean all the brands are made to the same specifications.

Actually had their names print labeled on cups, all in the details. Great Job!!!

Excellent video and presentation. The quality of the tests and information given has become my standard for these kinds of videos.

I liked the Kirkland oil video. I am a bearing Lubrication engineer at GM and help design the crankshafts and bearings for several of our engines including the smallblock engine over the last 20 years. I am not really surprised by your results. Probably the most important part of the label on the oil container is the Dexos certification. That is a GM proprietary certification and oil manufacturers have to submit their samples directly to GM for their approval. If an oil has the Dexos certification I would have no problem putting the oil in my GM car.

One of the best and most helpful channels on all of RU-vid. Thank you for all the effort, we love The Farm!

Thanks for all the testing you do!

I love your channel, subscribed.

“We’re gonna test that”.... T-shirt... just saying.

One of these days, companies are going to have "Project Farm Certified" on their products.

What a great test🎉 long video to make! Thank you w

I am impressed at your quality of tests!!! Unlike the others, yours is quality tests!!!

Costco: "Project Farm is on to us."

I love the all the research you're doing that allows us middle income working class folks to save money and protect our stuff!

Damn, this guy is thorough. What an informative video. Proud to be a new subscriber.✌️

Thank you for your hard work and for taking the guess out of choosing a motor oil.

A video idea is to test what is the best “Windshield Water Repellent” treatment. Here are some brands that are on the market. Rain-X, Aquapel, TriNova, Nano Safeguard, Invisible Glass.

Not surprised with these results. I've been a member of Costco since way back in the early Price Club days and cannot think of one Kirkland brand product I've bought that I was not satisfied with. There one of the very few companies that seem to care about there customers and really try hard to take care of them. As always another great video.

I've been using it on my jeep and the Kirkland diesel oil in my excursion. Can't beat the price and seems to perform well. Nothing has blown up yet!

Your reviews are the greatest

Make a shirt that says “were gonna test that”.

Warren makes excellent lubricants and have done so for many decades. Super Tech and Mag 1 are two of the most reliable and highest performing oil brands of Warren oils and you can't beat the prices. Warren probably puts the exact same oil in both ST and Kirkland bottles, the only difference being the labels. This is common practice in the lubricant industry and helps to keep cost (price) low due to economies of scale. Fantastic review -- keep up the great work!!

This is wonderful to have seen. Thanks so much for making this video, I've been telling people for years that SuperTech motor oil is absolutely fine to put in their cars, (especially older cars) and it's SUCH a savings and now with Kirkland using the SAME oil as WalMart, why not!!??!!

Love your content, thanks for the videos and your scientific approach to your experiments!

Test if the fire rating on a safe will actually save documents and or guns on the inside of the safe!

I just bought some Supertech High Mileage Full Synthetic for only $15 but felt a bit guilty. After watching this, I am excited for my next oil change and feel I got a great deal. As always, appreciate your diligence with the comprehensive testing and tireless efforts making these videos!

I watched this video again !!! Love it

Thank you for taking the time to do this fair oil test comparison. While using good synthetic oil does help, it also helps to change the oil more frequently. Going 4,5, 6,7 thousand miles between oil changes Vs only 3 to 4 thousand miles results in far cleaner internal engine components and less overall engine wear. Those little post office cube trucks we see on our nation's roads each day were all built during 1986 & 1988 and their 4 cylinder Chevy engines are still running reliably today almost 40 years after they were put into service and their oil is changed every 3,000 miles or less. Those Grumman built aluminum bodies and Grumman aircraft quality paint jobs on them while over 35 years old look almost as good as new.

Being a Costco employee for 30 years, I was very excited to see that we have our own line of full synthetic motor oil. Thank you for posting this awesome, informative video! Another excellent job by Project farm!

A Suburban with a quarter million miles on the clock. You're my kind of guy. Bless you, sir. Bless you.

New Subscriber. I have watched many of your videos. Great work and great channel. Thank you!. Greetings from LA California

Great info! Very thorough as usual!
