mixing oil

dsocold · 03-23-2017, 01:16 AM

i ended up with 2 diff oil brands both being castrol euro formula but one is 0w30 the other is. 0w40 would it be a big deal if i mixed them for one oil change ?

No big deal at all.

Even if you mixed different brands it wont hurt a thing, definitely wont hurt to mix 2 different weights.
