I have a saab 9-3 with the GM 2.0T Ecotec. Book calls for 0w-30 Mobil 1. I always like change so Ive used the 0w-30 M1, ive used 0w-40 M1, GC 0w-30, 5w-30 M1 and now have in there 5w-30 M1 HM. car has 130k on it now and burns prob 1/2 quart every 5K miles. Going on a 3k mile trip next week and I was thinking of trying out the Maxlife Full syn 5w-30. I have their Maxlife in the trans and its literally been a night and day differance in there since I got the car at 90k. I'm in love with the Maxlife ATF. Any thoughts? i'm usually an M1 guy but willing to try something new out.
