Viscosity Breakdown: The Silent Engine Killer Revealed!

Just like the old Castrol GTX ads, you want to avoid viscosity breakdown because when your viscosity breakdown, your engine can breakdown.
Viscosity is the most important characteristic of a lubricant, and there is a direct correlation between viscosity and wear - when viscosity breaks down, wear increases. We've demonstrated that in our past two videos:

• 20W-50 vs 5W-20: Which...
What Adding BOOST Did Do To Our Motor Oil (NA vs BOOST Test)
• What Adding BOOST Did ...
We also see that in the thousands of used oil samples we've analyzed. But here's the thing, not all oils shear and breakdown the same. Some oils breakdown quickly and significantly, but other oils barely breakdown. In this video, we will demonstrate viscosity breakdown in the lab, and show you the results.

Good information for the unknowing. Wide range oils with heavy modifiers do shear. But most people don't know what an HT/HS spec is and don't look for it. Some manufacturers are now omitting it (hiding it?) from the PDS and stating "we met the xxx.xx spec", which tells us little of where they were in that spec's range. They cleared a bar - that's all we know. What would be _very_ useful is these same shear tests run on a dozen popular oils in each of the 0W-40, 5W-30, and 5W-40 stated ranges. Perhaps with their HT/HS specs to provide some correlation. That would get us around the information shortcomings from the manufacturers.

Here is the way I look at the entire topic of engine oil and maintenance intervals. Most vehicles these days represent a significant percentage of the average persons annual expense vs income. This would be second only to their home. If my house needs a new roof, I'm not just going to put the cheapest material I can find on it, installed by someone that doesn't have a reputation or body of work that expresses quality. Same thing when we choose an oil for our vehicle, do your research and buy a trusted brand (or just have the dealer do it if you cannot be bothered.) Then do your maintenance often to protect your investment (AKA, don't always just do what the MFG recommends at a minimum.) Your investing in reliability and long term protection at a relatively small expense over time on both fronts. I love content like this that helps me make smart decisions on the maintenance of my vehicle! Thanks for the great video, Lake!

As interesting as this information is, it does not really apply to new modern gas, gas hybrid oils. Most if not all new cars run anything from a 0w8 to a 0w20 very few new cars these days even run a 5w30. So bringing up oils that are 5w40 or 5w50, 10w60 are basically race oils used by what less than 5% of oil users? It would be nice to see a test like this one provided but with the lighter viscosity oils and to see how they are able to withstand extremes of start/stop systems, hybrid start/stop and how these oils are made to keep your engine alive. I do see a shift in what manufactures are using in their base oils, going from a PAO, POE base to a Group 3 or Group 3+ base and relying more heavily on additive packs and polymers to make these newer oils. Would love to see a video on how these light viscosity oils can keep modern turbo charged, high output engines alive for tens of thousands of miles.

Newer gasoline engines (such as Lake's daughter's Corolla) are using lower viscosity oil. A video on 0W-20 or 5W-20 stability or the new 0W-8 would be very helpful.

@chulyn790 2 дня назад

Good stuff Lake. Running high volume oil pumps when the clearances and the pump choice do not dictate an HV pump means that the oil is being by-passed and going to the pump gear set again to chop or shear the polymers.

Interesting to learn about how timing chain can accelerate shearing of the oil. I’m guessing it’s more so a factor in OHC engines with multiple chains and sprockets vs a small chain in a pushrod engine.

@LTVoyager 2 дня назад

Given that most of us likely have no idea how the quantity of wear materials in an oil analysis correlates to engine life, a video on that would be very useful. For example, if iron is 50 ppm at every 5,000 mile oil change vs. 10 ppm, what difference does that really make? Personally, I suspect that even if every oil sample had 50 ppm of iron, the engine would still last 200,000 miles and with 10 ppm it might last a million miles. Given that few cars ever see 200,000 miles, are we talking about differences that don’t make a difference? Inquiring minds want to know.

@ALMX5DP 2 дня назад

Yeah I'm interested as well, though we have to keep in mind that engines can fail in a variety of different ways and some fail over many thousands of miles while others can fail more suddenly. For engines which last on the lower end of the spectrum, irreversible symptoms may develop well before that and influence decision making on keeping the vehicle overall. I'd still like to know what differences in OA values truly mean but will always try to be the most considerate I can be to ensure my engine is at least above average in terms of potential lifespan.

@LTVoyager 2 дня назад

@@ALMX5DP My point is simply that many things we do are in the “lipstick on a pig” category. I live in northern PA where we use copious amounts of road salt in the winter and rarely will a 15 year old car pass inspection due to unibody rust. Even body on frame vehicles like pickups seldom make it to 20 years. Given the 12,000 mile per year driving average, this yields 180,000 miles tops for a car and maybe 240,000 for a pickup. My last pickup was 20 years old when I had to get rid of it and it had only 160,000 miles. If 10,000 mile oil changes will get an engine to 200,000 miles reliably, then if you live in PA or NY or several other states, spending more money to change oil every 3,000 or 5,000 miles is a fools errand. It just means you junk your rusty old car with an engine slightly less worn than otherwise. Economically, it is insanity.

Can shearing be avoided by using a PAO-based "shear free" oil *without* any viscosity index improver? (These will tend to be, for example, 10W-40 and not 5W-40 or 0W-40 as the latter two can't be made without VII.)

You missed the most important test comparison! Test 20w-50 Vs 10w-60 and 5w-50, etc. You should have explained that HTHS depends a lot more on the BASE oil before VI are added. You did hint at it this at the end talking about your Porsche Boxster engine, but the point that needs to be made is oils that try to cover a very broad range (like 5w-50 or 10w-60), do so with large amounts of VI which can shear down and lose viscosity. For enthusiasts who never drive in cold weather and do not need low cold temp cranking at -30C, having a base oil that meets 5w or 10W is simply not needed. It is better to use a motor oil made from a base oil of 15w or 20W and achieve the higher temp viscosities with LESS VI improvers.
