Hi,
I just bought a new '13 Jeep Wrangler Unlimited, w/the new Pentastar 3.6L V6 engine. I noticed that it requires 5W-20 oil. I could of sworn that I saw a '12 model Jeep Wrangler, w/the same engine, saying 5W-30 on it's oil cap. Why the oil weight change, and is it safe?
I've so far got 500 miles on the engine, w/o any loss of oil, but I'm not very comfortable w/the 5W-20 in it.
With that said, what would be the best API (American Petroleum Institute) Group IV base oil, or better, synthetic engine oil to run in it once the engine is broken in? I'd like to use a REAL synthetic oil.
Is there a heavy 5W-20 oil available. When I say heavy, I mean like how GC 0W-30 is considered a heavy weight, while a 0W-30 Mobile 1 is considered a light weight oil.
I would imagine, that it has to be a Type SM or newer in that engine?
Thx
