Mixing 0w40 and 0w30
I had to do my own oil change, my FSS counter reached 0 yesterday and my dealer can't take me untill Aug. 20th. Nuf said. The local Advan. Auto only had 4 quarts of 0w40 and a bunch of 0w20, so i grabed the 4 quarts and head over to another place, no luck with 0w40 BUT they did have 0w30 (closer to 0w40 then 0w20). So I ended up having to mix 3.75 quarts or 0w40 with 2 quarts of 0w30 in my 1999 SLK230. Will I be ok for the next 20 days?
PS All oil used is Mobil 1.
