Thank you for sharing this informative video on base oil! I had no idea about the various types of base oils and their applications. The explanation of the refining process and the different viscosity grades was particularly helpful. This video has given me a better understanding of the importance of base oil in lubrication and its impact on engine performance. Keep sharing such valuable content!
Can you make a video about off the shelves race engine oils, which one you will considere the best or what to look for regarding, shear stability, temp resistance and wear properties.
What if any are the drawbacks of going for an oil that has the winter vs hot viscosity / flow further apart? Is the only difference VI and the increased modifiers needed to make the oil fit both flow ratings, are there no drawbacks from that or? My personal logic would have it that an oil closer in winter and hot ratings would perform better in the sense of longevity and robustness since there doesn't need to be as much of a compromise being made or not as many additives for viscosity and other reasons needed for the oil to perform well at both ratings which are further apart so you could dial the oil in better or make less compromises for hot vs winter conditions, is there any merit in this or are modern oils able to handle far apart ratings without any problems? The extra viscosity modifiers and additives needed don't bring anything negative in-terms of oil performance, longevity at high temp, aging, TBN, protection, oxidation etc? How come we don't see any further apart ratings such as 0W50 or 0W60 or 5W60 for example? Purely because of lack of a market? Would for example a 0w30 vs 5w30 vs 10w30 be any different keeping everything else the same in any way as far as protection and longevity go or is it only winter performance differing with no drawbacks in any way is what I'm trying to get at. If so, why would you ever run anything else then the thinnest possible winter rating that still meets the hot flow rating, there'd never be a reason to run 5w30 over 0w30?
In another video he mentioned that as the oil is used the viscosity agents break down, so your 0w50 might turn into a 0w25 or something that's less suitable for your engine over the oil change interval. Only true base stocks with less viscosity change will remain consistent over time.
Group 4 pao's is entirerly man made oil and is synhetic oil, group 3 cracked or any other process it is still group 3,not truly snthetic. 1990'S court Rulling allows company to call highly refined group 3 oil To be called 100 percent synthetic. Is thic correct? Pleasae reply
Great video, awesome to see this sort of info appearing on RUclips with a high presentation quality. I appreciate the time taken to produce it

Thanks for this video. I really liked the example of manufacturing a 5w30 oil with the different compounds and additives
Superbly produced video embedded with excellent educational material, Rafe!
At 3:00 the chart shows Group 3 oil at a Viscosity Index of 80-120, when they can acctualy go much higher!
Would you like to consider making a video about used oil recycling
Thanks Rafe, good content.

Well presented facts. Appreciate the speaker.
For the same 5W30 I can have a mediocre base oil with a lot of additives or a solid base with fewer additives. I think the second is the best!
Great content!
I found that aero 120 works well in my two stroke motorcycle.
Well done.

Where are the synthetic base stocks sourced from?
Mobil 1 motor oils are mostly Group III; does ExxonMobil buy Group III from other suppliers?
Okay to ask you a question, Please.
Group 4 pao's is entirerly man made oil and is synhetic oil, group 3 cracked or
any other process it is still group 3,not truly snthetic. 1990'S court Rulling allows
company to call highly refined group 3 oil To be called 100 percent synthetic.
