The holidays put me in a reckless mood, so I switched from the spec 5w-30 to 5w-20 in my 2000 Saturn SL1 SOHC for winter. Here is my logic, such as it is:
1. Luckily my car burns much less oil than most S-series do----but it still burns some. If the 20-weight makes it burn a few drops more than before, so be it.
2. Engine noise? Hehe. This is a Saturn.
3. Might not even be enough to notice but I will happily take a tiny bump upward in mpg.
4. Want to test the theory that with an S-series it's most important to get oil to the chain ASAP; the chain runs the show, pretty much. Figure a 20-weight will get there the quickest. I've read a post or two at Saturn Fans that suggests that, anyway.
5. I am running PP with an M-1 filter; consumption is less with PP or M1 than other oils. (M1-HM the best with PP a close second. Since PP had a rebate deal that's what I got.)
6. Winter in northern PA is about to hit full stride.
7. Feeling reckless.
Any minute now the engine is gonna blow....
