10w-30 Maxlife syn OK for winter?

Yeah I got some at a great price too. 10w-30. I am gonna go back and see if they have anything thinner to mix.

I'm using it straight in a 05 turbo Subie. Coldest start so far in mid-30's F. Turned right over, no clatter. Engine seems to like it; runs smooth, reasonable consumption. About 38k miles on it.


Nice oil AFAICT.

I ran 10W30 ML syn SL in my 2000 Tundra last year. On a hunting trip to South Dakota with early morning starts in the low to mid teens F, it would start fine but with a grinding/dieseling sound for a few seconds. I made the same trip this year with PP 5W30 SM (old formula) with similar morning temps and had no grinding/diesel engine like sounds.
FWIT, I'd recommend finding a jug of 5W30 ML syn for the winter and save your 10W30 for summer.
