Due solely to the API license change? Amazing.
Correct. 2% is probably a bit high for one grade.No oil will change fuel economy in any noteable way, you might see something like a 2% difference averaged across a large fleet switching from 5w-30 to 0w-20, When individually fuel economy changes it has more to do with the difference between winter and summer gas and whether you're running the AC less, changes in driving habits, etc, changing between different oils will have virtually no distinguishable difference in fuel economy at the individual tank level assuming all other variables are the same.
A little dab will do ya!I dunno. Last tank run same thing. Got to around 330 miles and needle had good amount to go (about 1/6th) E-1/4, light not on yet. I'm gonna run this tank down and do the math. I'm also starting to notice other things happening too. My eyesight seems to be getting better. And I noticed I have more vitality and areas of my head which have long been devoid of hair are starting to regrow. Possibly all thanks to Chevron.I was thinking about dipping a lottery ticket in some to see if it might better my odds.
