My wife’s 2004 Trailblazer is starting to use around a quart of oil between changes. It’s got 200,000 miles on its 4.2 liter I-6, so I guess it’s been a good one.
What I’m considering is using heavier weight oil than the 5w 30 it’s always used, and would like some advice on what to use. I’ve thought about 10w 30 or 10w 40 to slow down the oil use. What do y’all think?
