dont know what kind of saturn you have, but i am driving my wifes 97 sl1 and it burns about 1 quart every 2-4 weeks. does not seem that bad, car has 122k+ on it, so i am expecting some.
I bought some stuff at Autozone for four cylinder engines, something high RPM and it said it would help with oil burning, I put that in my last oil change and havent burned a drop, I think STP made it
