My 2008 Wrangler 3.8 has always had a drinking problem, at least since 40k miles.
Sometimes it uses 3/4 quart per 1k miles, sometimes none. Mostly, about 1/2 qt per 1k miles. I had 1 cat replaced at about 100k miles, under warranty. Now both need replaced at 155k. The engine otherwise runs like new.
I've mostly run Mobil 1 oils, 5w20 or 5w30. Occasionally She'll Rotella Gas Truck 5w20, which is in it now. Always 6k OCIs to comply with lifetime power train warranty requirements.
I'm now looking to protect the cats. I'm looking at Mobil 1 ESP oils, particularly 0w/20, 0w/30, or 5w/30.
It is a daily driver (35 min commute) and occasional technical off roader with some lightweight fishing boat towing in the warmer months. (1500-1750lb boat/trailer/gear.)
I'm keeping this Jeep for many many years to come.
I'd be interested in thoughts and opinions on this move and the different weights.
