ok, my 1994 SL1 seems to want to lose close to a quart of oil every thousand miles with a 5w30 oil. I've tried 5w40 Rotella Synthetic and the oil consumption seemed to go down quite a bit(2 quart in 1000 miles) but that oil didn't last very long, after 2500 miles it was already showing noticible wear. I was considering going to some good mobil1 0w40 but I'm betting that'll leak out of my front main seal. Auto-RX didn't seem to do much forthat leak, but I'm only 345miles into the new dino oil and aparently it is still working on that for 500. I'm really not in the mood to spend big bux for synthetic oil I'm just gonna have to dump more of into my engine.
so I figure I'm just gonna give up and add oil every 500 miles like most other saturn owners. There's so many treatments that seem to work for some people and not others. The car is going on 9 years old and has 161k miles on it. A quart per 1000 miles is acceptable by the manufacturers anyways. Oil consumption does seem to be slightly less with a 10w30 as opposed to the 5w30 but the manual says no 10w30 under 20f which I've been starting at around 5:00 every morning here lately so I'll use it in the summer.
What is a good oil on the heavier end of the 30wt scale that I can use. The engine makes a strange whining noise with dino 10w40's for some reason. I'm prety much set on schaefers #701 for the winter, does that sound like a winner?
