My wife has a Jeep Cherokee with 2.4L engine and not quite 20,000 miles on the clock. Since new, the engine has burned oil at an alarming rate. At 3,000 miles or so, I checked the oil and it was a few quarts low. I had to add 2 quarts just to get it to show up on the stick, and another quart I believe to get the level into the hatched zone on the stick.
Since then, I've monitored her oil level more religiously and I have to add quart(s) of oil on a regular basis.
In reading the Jeep forums, it seems that this is very common on this 2.4L engine.
The dealership has offered to do an "oil consumption test" for us. But, I don't know how that works and I assume they'd have to keep the vehicle for a long while. My wife wouldn't like that. Also, there is a high liklihood that we'll go through that whole process and then they'll just declare it "within spec" and nothing would be done.
So my question is this: Factory fill is 0W20. Could I possibly slow down the oil consumption with a 5W30 synthetic instead?
