I'm a new member here and would like to know what is the best oil to run in my Jeep Wrangler. It's a 2001 4.0 L has 119,000 miles and I use it for my daily driver. I live in Florida and don't drive the car real hard. I've never used a synthetic oil in it and don't off road. I been using 10w-30 with a Mopar factory oil filter, I believe that's what the owners manual recommends.

Also just curious, who makes the Mopar oil now (2013) ?

Thanks.

Rotella T6 5w-40 is an EXCELLENT oil for the 4.0. Has higher zinc, very good add pack and UOAs return good results; the 4.0 tends to like the 40 grade oils.

It's synthetic, but I switched my 2000 4.0 to synthetic in 2010 and it didn't fall apart like everyone says.

I think the filter mounts different on a Wrangler, but if you have the filter mounting parallel to the block, go with a Ford FL-1A filter.

That engine will be happy with anything from a 5w30 to a 10w40. Many on here recommend the Rotella 5w40 synthetic or Rotella 10w30 semi-synthetic for the 4.0L. The 4.0L is a somewhat noisy engine that is more closely related to a tractor engine than the modern gasoline engines in cars of today. Both me and another member on this site have found that Pennzoil Yellow Bottle conventional has made a significant difference in quieting down our engines. I would use the Pennzoil Yellow Bottle 10w30 or 10w40 considering your climate.

The Mopar filters are a good filter made by Purolator to Chrysler specs.

You can do what you're doing and be fine. The Rotella, as mentioned, would be a fine choice.

I second the T6. It's $21/gal at Wal-Mart and there's a $5 rebate for two gallons from Shell right now.

On the Rotella shouldn't I use a 10W-30 like the manual says and especially in Florida?

You'll be fine with T6. Those engines love the stuff. 5w-40 is fine. If you search around, you'll find a bunch of guys using it in their 4.0 Jeeps with great success.

The 4.0 engine takes 6 QTs. At least my 2001 does. But more oil is better.

AAP has Rotella T6 for $13.49/gallon (less than Walmart), its a sale but not sure for how long. I bought the last 5 gallons at my local store.

I use PP or PU 10W30 in mine.

The engine is bullet proof except for the casting #331 heads that crack, and the piston skirts that crack.

I didn't think they made T6 in a 10W-30. PU or PP ?

The oil and filter you are using a good combination for your engine and the type of driving you mentioned. I see no reason to change. My 95 GGC was sold running 10w30 std Pennzoil and sold at ~ 180,000 miles running well without any major issues. The only major service, if you call, changing a rear oil seal major was the only thing done to the engine other that normal maintenance. Ed
