Oh yeah I’m changing the W Value in my beetle I run 20W-50 in the summer and spring and in the fall and winter it runs either straight 30 or 10W-30/40 and in my truck it runs 10W-40 and 20W-50 then in the winter it runs 10W-30. The only thing I run a 0W-20 in is my moms car because that’s what it calls for I wouldn’t put a 0W anything in my cars that are 30+ years old.Thanks for the input!! Yeah I think I’m going to switch to 5w20 in the summer cuz we do get plenty hot and then back to 0w when we get super cold in the winter.
For your older cars are you changing the second value as in the one after the w? Or the first?
cuz the first makes sense to me cuz that depends more on the temperature we live around as in super super cold then 0w is a good bet. Super hot then 5w and 10w is good. However I don’t understand the movement of bumping up from a w20 to a w30
