Was thinking of trying it. I just don’t understand how the oil can be a zero weight cold then a 40 weight hot?? Or am I not getting it
Thats what my RAM 2500HD with 6.4 calls for. Not the easiest to find. Not sure if there would be any noticeable gain. Just remember that oil is made for engines very different than our dinosaur engines. Not sure what tires have to do with this????
I was theorizing the zero weight would be easier to start flowing cold and not have 90 lbs cold pressure when trying to accelerate SLOWLY until the oil warms, and the weight of 40 oil after it’s warm. Might just be my thinking is off LOL, I’ll just stay with 10/40 synthetic
Lots of additives when the oil is being manufactured. Viscosity index improvers or modifiers. The drawback is VI modifers are more susceptible to shear
Still only a ZERO weight oil. If you have super tight clearances maybe OK. But I'm more concerned with hot oil pressure. If you can still pull 80lb at 6000 rpm with it fine but I doubt it. Most of these thin oils are for fuel economy...not much protection hot...IMO
I run the same in my 2018 6.4 Power Wagon. I've been getting my oil on amazon. https://www.amazon.com/Pennzoil-550040856-6PK-Ultra-Platinum-Synthetic/dp/B00JMCCE6U
0 weight oil does not exist until it is warmed up. I think it is made of Schrodinger's cat and Mermaid scales.
I see that all the time on the oil fill caps of late model turbo 4 cyl, 0w-20 That oil has gotta be like mineral spirits hot
My 14 GMC pickup with a 5.3 L calls for 0w20. When I change it I'm always thinking wow is that thin!! Comes out like water.
Years ago Volvo was going to get a hefty fine for not meeting CAFE standards....so quick fix was specify 5W-30 oil vs 10W-30 on all models. Know someone with a Dodge that had 175K and used oil. I said switch from the 0W-20 to 10W-30 and I bet it would be barely burning any. They wouldn't do it and traded it in for next to nothing.....
I have always run 5-30 in my 350 Buick race motor but keep in mind that I run it real cold. I try to stage it at 110 where it runs the fastest. Most wear is caused from startup do to oil flow time though the oil passages restricting oil . Thinner oil gets to bearing faster and lubes better at cold temps. When qualify I use 0-20 race oil . Im also running this in My 370 and 426 2009 Dodge Challenger. 5-30 in daily drivers My 2018 Chevy truck 6.2 takes 0-20 .
