Type of Oil Viscosity to use for a SAAB 2005?
when i went to pepboys to buy synthetic oil, i was told i had to use 0w-30 oil. however, in my car manual, it states exactly: For best function Saab recommends:
For gasoline engines:
SAE 0W-30, SAE 5W-30 or SAE 0W-40 engine oil.
go with the 5w-30 as thats what almost all new cars use.
