Somehow researching different oil types in refrigeration compressors brought me here. Thanks for providing so much good information though - I had a mechanic say that my 81 Volvo 240 doesn't care or need synthetic but now I know that there are differences it will make whether it "needs" it or not. Also for refrigeration we have a few different oils we use: Mineral, alkyl benzene, Polyolester, Polyvinyl Either, and Polyalkylene glycol. The type depends on what mixes with the refridgerant, but POE likes to turn back to acid in the sealed systems which isn't great..
@@LubricationExplained If it's within your scope of expertise, I want you to discuss the different types of thickeners (mineral soaps, calcium sulfonates, polyurea, etc) used in industrial greases and their corresponding applications.

We can assume that group 1-2 is naturally aspirated lubricant that does the job with classic minimum additive package. Have to admit that I experienced SAE 20 monograde pure mineral oil with liquid MoS2 additive in my car. It runs freaking good compared to so called Fully Mega Synthetic oils. The engine runs much smoother and sounds so refine. Will report later after 100 engine hours. Thanks for video.
The should print this stuff right on the container. I found a relatively cheap manufacturer with fully synthetics in 0w40 and 5w40 that are basically pure Group 4 PAO with tiny amounts of Group 3 and Esters, most likely from the additive package. Such an oil is almost unheard of in my country. You only really find out about this stuff when digging up lab reports.
@@LubricationExplained videos regarding transmission fluid (auto, manual, CVT, and DCT fluids and their differences) and videos about heavy weight gear oils, might also be good to point out the differences between straight weight and multi-weight oils

When the label says "conventional oil", should i assume immediately it's a "group i" base oil? If not, is it possible to shop specifically for "group i" lubricant?
There's not many Group I engine oils left to be honest. "conventional" will usually mean either Group I or II, so that's definitely a clue, but full Group I's are hard to come by because of the low viscosity index.
Looking at Nulon and Penrite, Nulon use group 3 oils for their top of the line gear oil while Penrite state a PAO Ester blend, yet the Nulon state a higher viscosity index. Comparing 10W-40 engine oil to 75W-90 gear oil being similar (almost identical) at 40-100, I wonder if Nulons PAO/AN race oil cold be used as a gear oil also if the anti wear properties are similar. There does not seem to be a defining difference between gear and engine oil. As a mechanic, some of the vehicles (BMW) used engine oils for the transmission. If the transmission never reached temperatures above 100c, would a pao/an oil be of any benefit? What do you think about this.
@@LubricationExplained I have two cars 1 is a 2007 Chevy equinox that recommends a 5w-30 synthetic but I’ve been using a store brand made by shell 5w-40 because the engine burns a bit of oil and the thicker oil helps burn off less. Is it bad to use euro spec oil in a American car I’m scared might ruin the catalytic converter. And the second car is a Mercedes b250 2018 and its specked for a 5w-40 with the mb229.5 approval for warranty. I’ve been using Mercedes oil which is sold by the litre and its very expensive and I’m sure it’s a group 3 synthetic. Any input would be appreciated thanks again and you have great videos keep up the great work.
