Is there a specific oil you have used that you noticed worked better our saturns mostly the 1.9l. Any oil that actually did slow oil burning. And I've tried piston soaks with mmo seafoam, berrymans, and ac delco top engine cleaner. I use a quart every 1400-1500 miles with 10w40. Right now I'm using Valvoline conventional but Its expensive for a conventional and hasn't made any difference over Mobil . Just seeing if anyone has personally used some kind of oil that made a marked difference. Thanks guys
