*Clarification!* There still seems to be confusion about the viscosity decreasing with heat, yet the number is higher, for example 5W-30. 1. This is explained from about 1:05 to 3:05. 2. All motor oils (basically) will decrease in viscosity as they heat up (become thinner). 3. Motor oils will increase (become thicker) in viscosity as they cool (as demonstrated in the video with graduated cylinders). 4. A 0W oil has a lower viscosity than a 10W oil when it is cold (the number is lower). 5. A 40 grade oil is thicker than a 30 grade oil when it is hot. 6. A 10W-30 (as shown at 2:28) will be thicker at cold temperatures, but thinner at high temperatures, versus a 0W-40. 7. The rating is temperature dependent! There is a cold rating, and a hot rating, which comes from tests (shown at 3:17). 8. Even though the number increases as it gets hot (like 5W-30), the viscosity decreases. It means the oil behaves like a 5 grade oil when cold, but a 30 grade oil when hot. How? 9. Viscosity modifiers are molecules that expand as they heat up, which decreases how much thinner the oil gets as it heats up. It still gets thinner, but not as thin as it could get if the viscosity modifiers were not in there. This is what makes it a multi-grade oil. Because it behaves like different oil grades depending on temperature. 10. In summary, a 5W-30 will decrease in viscosity as it is heated, however its hot rating is a thicker grade oil than its cold rating. See plots in video (2:28) to see what this looks like.

Thank you for the clarification! What has gotten me all these years (and perhaps some other viewers) was thinking the number was an absolute measurement of viscosity, hence thinking 30 would be thicker than 10 in a 10w-30 oil. Similarly, thinking that just a base oil would change it's grade number as temp and viscosity changed. It seems your "behaves like" statement is what I should have keyed in on. If I'm understanding now, a 30 grade oil will always be a 30 grade oil, regardless of what temp and viscosity it is at any given time, and the two numbers in a rating just signify different characteristics, and not straight up measurements of viscosity itself. Pardon my long comment, but basically THANK YOU. These videos are so informative.

As with any car manufacturer there is always one exception to the owner's manual. The current Subaru engines all use the 0w20 oils. The same engine built in Japan all use the 5w30 oils. There are a great many cases of oil consumption in these engines in the US using the 0w20 oils. Most when moving to the 5w30 oils can eliminate the oil consumption issues. Since I live in an area that can have colder winters I elected to run 0w30 oils in my Subarus.

I had my subaru tuned by the leading engineer of mitsubishi's efi setup, when mitsubishi closed down here in adelaide/south australia, he started his own tuning business - steve knight racetech. He told me to go higher on the second number to 50 or even 60 (so 10w50) when I do track days or go drag racing, as the oil takes longer to be displaced in the bearings and will prevent spun bearings, and never go to a smaller number unless I wanted to spin a bearing. He built and rebuilt many race engines in his life. I follow that rule, and have never damaged an engine.

That's changing as manufacturers are building their engines to be tailored to lower viscosity oils. They now have tighter bearing clearances, are engineered for high *flow* instead of high oil pressure, and use vane-style oil pumps that are optimized for the viscosity the engineers designed the engine to use. Contact the manufacturer if tracking a vehicle and are concerned about oil viscosity. Most will probably tell you to use a heavy weight oil on race day and immediately drain it out and replace it with the correct oil after racing.

I'm an aircraft mechanic and I used to work in gas turbine engines.(jet engines) The synthetic oil used in those engines that reach 60 000 rpm was so thin you couldn't tell the difference between the oil and the jet fuel.

@Tah BOO in a jet engine, the bearings are hydrodynamic. The rotation of the shaft creates a boundary layer and the shape of the bearing has shallow semi-circular pockets machined into the bearing on either side of the loaded area (the oil inlet is typically in these pockets as well.) that acts like a wedge to force the oil to compress in the areas that have higher load to maintain the oil film. Whereas hydrostatic bearings simply use the pressure generated by a pump to force oil into the annular area between the bearing and the shaft.

I dont give a rip about milage. Thin oils are there to increase CAFE mileage numbers, NOT reliability over time. When I was younger I knew professional race engine builders. When they built a drag engine that only needed to last a few seconds, they used exceptionally thin oils for max power. When the built an endurance racer, they built for 40 or 50 wt oils, and beat it into my head for longer life I should be using 20-50. I have seen hundreds of common street engines shredded to crap at 90,000 miles on that thin crap oil used for high MPG... and many running fine at 300,000 when they live with higher viscosity and 'stickier' surface adhesion oils.

You can usually drop the cold number with no issues. Cars from 20-30+ years ago may call for 5-30 or 10-30 because there was no 0-30 available at that time and the dealers dealers would have to stock a new oil. I run 0-30 in older cars and trucks at our landscaping company and in my personal cars we had no oil related failures. A 0 weight oil may even provide better protection since it can quickly get into all areas of a cold motor.

When the automotive industry talks about 'adequate protection' for the 'life' of the engine what they really mean is that it won't fall apart or start smoking during a cars typical life span. That does not automatically mean a different oil won't offer more protection or extend the life of the engine. I'm skeptical of claims the automotive industry make. Automatic transmissions that are 'superior' to manuals for example where they are horribly programmed and refuse to dowshift yet upshift at every opportunity because drivability was tossed out the window in favor of fuel economy.

They’re meant for the dead of a Canadian winter or August in Texas so you CAN fudge those numbers depending on the climate where you live, just don’t go down (ie 5w30 to 5w20). Up though, especially for the year-round “hot” climates like Texas there is absolutely no problem raising those numbers. In fact it’s probably recommended. You’ll never have the low flow cold start problems to worry about but rush hour traffic on the freeway when it’s 105*F ambient and 130*F+ on the road with your AC cranking and no airflow through the cooling system your engine will appreciate the extra viscosity.

Thank so much for making such clear sense of oil viscosity! It’s crazy to think I’ve been wrenching on cars for almost 30 years and I’m just now understanding what the numbers actually mean. The main reason I wanted to know is because I just had my first complimentary oil change done on my 2022 Hyundai Elantra N. The dealership put in 0W-20 when the manual calls for 0W-30. After calling a different Hyundai dealership and Hyundai Customer Care, they all confirmed despite what my owners manual says, they can put in either 0W-20, 0W-30 or 5W-40. Needless to say I was both confused and concerned. I had a Hyundai tech on one of my FB groups insisting that’s not true and I should only be using 0W-30 like the manual says. Long story short I now understand the difference between the oils and will be draining the 0W-20 and filling it back up with 0W-30 ASAP.

I recently purchased a used 2017 Honda Fit automobile and was surprised that the engine oil spec'd in the owner's manual for my area (northeast USA) is 0W-20. That thin of an oil runs against my thinking..but I have to trust that the engine was designed for that weight oil. My 1992 Corvette with LT-1 engine is spec'd to use 5W-30 synthetic only..and I was surprised at that weight (but not surprised spec'd for synthetic only). It's amazing to me that modern automobile engines are spec'd for lower weight/viscosity oils..used to be I routinely added a pint of STP oil additive when I did oil changes myself but that was years ago for small block V-8 engines. Now I get oil/filter changes done at a local garage they always put in the oil spec'd by the manufacturer I have to trust that is best for the engines.

The best aspect of this presentation is clarifying that the two parts of the multigrade designation are not about WInter vs. Summer (although I think that was the origin of the 'W'), but Cold Startup vs. Hot Operating. HOWEVER, there's a catch with manufacturer's recommended viscosity. When running the EPA fuel economy test they look for every possible legal edge to improve the results (because marketing). One of those tricks is to test drive with thinner than optimum oil viscosity. BUT, they are then legally obliged to make that grade their official published recommendation (i.e. your owners manual). That is why I don't worry about running slightly thicker in summer. My OM recommends 0W-20 and I have no concerns running 0W-30 in summer.

I use a 0w instead of the recommended 5w on my car, but I live in Canada 🇨🇦. So the 0w is definitely better in -30 celsius.

The real question is: can a high mileage car run on the same oil grade than the one when it was new? Do climate play a role in oil viscosity?

@coryholbrook4643

3 жыл бұрын

Yes, climate plays a huge role in oil viscosity. Hot climates like in the southernmost states of the United States don’t often or continuously stay at or below freezing so thin oils are not needed for cold start flow. The thin oils are for the subzero winter dwellers anyways. But summertime temperatures are much higher thereby increasing engine operating temperatures and oil temperatures, especially if one commutes in high population density metropolitan areas where traffic is a common hinderance. With old engines, if it’s a properly maintained system bearing wear should still be minimal even after 100,000 miles. Bearing clearances are what affect oil pressure the most so as long as those remain good thicker oils will do nothing to extend engine life. Cylinder wear isn’t really an issue on modern fuel injected engines unless, again, the vehicle’s maintenance history is just abysmal. But cylinder/ring wear is what usually causes oil consumption but with worn bearings or worn cylinders thick oils are just a bandaid over an amputation, they won’t save your engine, they may not even buy you time. They just make you feel better until the inevitable happens. Should’ve changed the oil on time and used a quality filter.

Climate plays a major role in oil selection. If you live in Chicago, extremely cold starts are normal in winter. A lower "W" number can save your engine, and allow for faster warm up. But, if you live in Los Angeles, winter freezing are not an issue. During sustained driving on long freeways, and highways, and especially long trips through desert conditions, means your high end viscosity can become critical. It is always smart to allow warm ups before driving after long cold nights. Change your oil before it begins to break down. This keeps internal dirt, tar, and debris to a minimum. Always use better brand filters!

On my current car Audi recommend 5W30, but on a couple of occasions i found it too thin for the summer in the traffic jams to the point where the "low oil pressure" lamp came up so i drove it to the garage and after they disassembled the entire engine found out there was actually nothing wrong with it, it was just the oil wasn't viscous enough at these high temperatures (usually anything above 40°C). And because there wasn't 5W40, went for the 0W40, the problem went away immediately and later in the year i found it helps for much smoother starts in the cold winter mornings and nights. It's strange however that manufacturers don't include table with different climates and recommendation of oil grade. I remember in my 1990 VW Corrado manual the 15W40 was recommended but in temperatures lower than -15°C or altitudes above 1500m the 5W40 was noted as well as when there's a lot of short city driving.

Always well explained, thank you!

thanks this really improves my oil knowledge

11:40 The owner's manual for my vehicle calls for 5W-30, but says that 10W-30 is acceptable for temperatures above 0°F if 5W-30 isn't available. It goes on to state that 0W-30 is acceptable for temperatures below -20°F. In general, the cold viscosity grade is less critical than the hot viscosity grade since it only affects engines at cold start-up.

I've found that using thinner oils results in moderate oil consumption. When I use 5W30 my 4 cyl car uses no oil between 5000 miles OCI. Using 5W20 the same engine is about 1/2 qt low by 5000 miles. The engine has 45,000 miles.

It could be because the mechanics have to fix the engineers mistakes.

Sometimes the owners manual or service manual is wrong (no longer the best) and third parties have verified an alternative works better, especially if dealing with cars that are 20-30 years old and technology has improved

Engineers are human also and far from perfect. Also new models are always coming so not enough time to "perfect" the engineering time to move onto the next model

Very informative and well done, thanks!

Great video and that engine is a work of art.

I liked the ball bearing test, I really would have liked to see the 0w version of the drop test though.

There's very little difference between 10W and 0W at 0C. 0W is able to get much colder though before thickening up too much.

@@leoyru.3361 Not much difference to the eye, which would be true for two oils very close to each other on the SAE scale. The 0W will be little less dense and flow faster but not a huge difference. As temperatures rise it will be more dependent on the non-W number. It would have been interesting to see it compared to an SAE 60 oil.

So, it's recommended that I use a Chevy C8 with my oil, well that computes quite nicely.

Exactly depending of climate conditions, how you use the vehicle and miles you got on the clock.

Thank you Very knowledgeable person you are Great job You really really are awesome And we do learn from you I do appreciate you

Love this channel. I hardly ever have further questions after watching any of his vids. He seems to answer what you may be thinking.

"how cool is that engine" man, that finish they put on the steel is so enticing. I wish i could touch it.

Nice lecture, question though, what if im modifying engine like lets say increasing the compression ratio by replacing pistons, does the lowering the lower value and increasing the higher value become a must or should i still stick to the manufacturer's recommendation?

Thank you for adding Vietnamese subtitles to this video ♥️
