Wear…
And the ones that understand Tribology and the correlation between viscosity/MOFT and wear don't.
I would say that would be the car manufacturer engineers who wrote the specs. You are just a BITOG oil “expert”.And the ones that understand Tribology and the correlation between viscosity/MOFT and wear don't.
Yeah, the car manufacturer engineers that were basically forced to by CAFE to save the company millions of dollars in possible CAFE fines. Take CAFE away and you'd see much different oil viscosity recommendations, like seen for the same engines in different countries without CAFE.
Good choice. I got 5/5L jugs of VST still left. I don't think I'll be buying it again after the latest steep price hike.
There is NO logic in your comment. Yes, 1.5% is 1.5% and in other news, water is wet. SO WHAT?! We are talking about whether or not 1.5% of 25mpg is significant and IT IS NOT!
Sure there is logic, because I've never addressed what my option was with respect to the gain in fuel mileage based on a percentage like you have. I'm talking purely mathematical logic, and you're off on some "real world opinion" campaign.
1.5% is 1.5% regardless of anything else or someone's feelings about it.For the love of thinking humans and logic...THE GD X DETERMINES THE GD FINAL NUMBER AND THAT IS JUST A FACT!!!!!!!!!! IF THE X IS ORDERS OF MAGNITUDE LARGER OR SMALLER THEN MULTIPLYING BY 1.5% GIVES AN NUMBER ORDERS OF MAGNITUDE LARGER OR SMALLER. THE 1.5% IS A CONSTANT HERE AND IT DOES NOT CONTRIBUTE TO ANY DIFFERENCE IN ANY CALCULATED NUMBER. THE X DETERMINES IF THE 1.5 IS SIGNIFICANT OR NOT.
... melt down. You're infuriating yourself because you just can't get what I'm saying and it so simple. Sure, the X times the percentage determines the final number. So what? 1.5% of X will always be 1.5% of X regardless of how big or small the number is. In the end, it doesn't matter what size the resulting number is, because it's still 1.5% of X. What can't you understand in that, which is what I've said all along. Sure. 1.5% of a small number is a small number ... so what, it's still a 1.5% change. Wound it mean more to you if it was 2%, 5%, 10%, 25% ... ?? When does it become "important" to you, and when does it become important to anyone else.Your comment is stupid and immaterial to the discussion. Kinda like saying blue things are blue...no poop, Sherlock...BUT WHAT DOES IT MEAN?! The 25mpg MAKES THE 1.5% NOT MEANINGFUL.LoL ... I never said there was "no difference" between 1.5% of $1 and 1.5% of $1M" ... that's something you're fabricating in your head on off in the weeds with some tangent argument which I didn't even address. You're missing the whole point here. It's amazing how some people just cant' grasp simple concepts. My comment is simple and will always be true. 1.5% of X will always be 1.5% of X and be an exact number, regardless of what someone thinks it means in the "real world". That's all just someone's "feelings". Math doesn't care about "feelings".
You mean the number 5 is the number 5...his "argument" is some weird strawman arguing the obvious when the discussion is whether or not moving to 0W-8 oil has any real-world significance? It does not because it represents 0.375mpg.
In your opinion.
Not to you ... but it certainly could to a lot of people, especially big car manufactures who could literally save millions of dollars on CAFE fines. Is 1.15% of $5M make it any different in your eyes?
YES!!!!!!!!!!!!Because 25% of 25mpg is a 6.25mpg improvement!!!!!!!!
Read this post until you get the simple logic - Post
What if you were a car company that made 3 million cars a year that would be fined quite a bit of money each if the feet of cars didn't meet the CAFE target? See post #115. Would saving 1.5% of millions of dollars make it more important to you? The guys specifying thin oils like this have one main goal, to save CAFE fine money ... not really to save one individual guy some fuel money.
The industry-wide fleet average for 2024-2026 needs to be 49mpg....0.375mpg represents 1.56% of the difference between 49mpg and 25mpg. It gets you virtually nowhere. It is a complete waste of effort.
Get ready for other engineering attempts to make engines more fuel efficient. But thinner and thinner oils is still one of the main tools the CAFE whipped engineers use. Nothing will change that.
Except perhaps a clue...hard to defend any vehicle engineers these days with the junk they produce.
