In the two years I've owned my Saturn ('95 SL1) I've notice that the oil has a tendency to darken rather fast.. faster than any other cars that have been in the family garage. When I speak of fast, I mean in about 500 miles of driving, it looks like its halfway between the new golden color and used blackened oil.
The car has 68k, I used dino 5w-30 when I bought it at 45k, then switched to Mobil1 5w-30 and 10w-30 around 57k. I had a piston ring service done at 53k by Saturn, and have been thinking of going about 6.5k on the latest fill of M1 10w-30, but I'm a little leery. I'm sure a UOA would be good, but I haven't yet justified spending $20 to find out, you know, college student budget. (BTW, I'm running M1 to avoid any more piston ring sticking, common on Saturns)
So, without doing a UOA, i was wondering what the oil experts here thought about this.
