Hey guys, I wanted to ask about oil viscosity for my wife's 2011 Jeep Liberty 3.7 V6. I changed the oil tonight using Mobil 1 Synthetic 10w30 in the 5 qt. jug. I know it said to use the 5w20, but I like using the 10w30, and I've had great success with it. That should be fine to use, ya think?
2011 Jeep Liberty 3.7L V6, ok to use 10w30?

It will be fine but not ideal. I would have stayed with 5W20.

They aren't going to be happy with it if you have a warranty claim.

The likelihood of an oil related problem are slim and none, but I'd not recommend using 10w30 in it till you're out of warranty. Not going to hurt anything but I wouldn't make a habit out of it.

Statements like this one make absolutely no sense.

Plain and simple, the 10-30 will work fine!

It was spec'd for 5W30 until 2006, 2007 they made the change to 5W20. 10W30 would be fine, 5W30 would be a better choice if the OP feels the need for a 30 grade oil. Keep in mind a 20 grade for the warranty though.

Probably wouldn't hurt a thing. At the very least, follow the OCI.
Thanks for the replies guys. I've used 10w30 in everything I've driven, including my current vehicle, a 2000 GMC Sierra 2500 with a 6.0L and 193,000 miles with absolutely no drips or leaks. That's why I said I've had great success with it. I truly didn't think it would hurt anything either, but if it seriously comes to warranty issues I'll just switch it back to the 5w20 on the next change.

Sounds right; I owned an '04.
