I have a 2006 Jeep Wrangler X 6 cyl 4.0L, and Mobil 1 10W-30 was recommended by JF, the manual and...http://jeep.us41.org/.
Quote:
5W-30 oil can be used. 5W-30 is more fluid at cooler temperatures, but in the heat it breaks down faster. So, 5W-30 might be useful for someone in Montana during the Winter to prevent extra engine wear and assist with cold weather starts, but for the most part, 10W-30 is the oil for your engine.
May be different depending on the average temperature where you live or driving conditions/habits (towing etc.)

0W-30 is for Hybrid engines.

What? It is for any engine. More so for colder climates.

I ran it this past winter, no difference in fuel economy, lifter noise, or performance what so ever!
switched back to 10w-30 last oil change, intend to stay there.

I would doubt that the M-1 0w30 has the higher levels of Zinc required by the 4.0, the M-1 High Mileage 10W30 does.

The only thing 0w-30 will do is allow your motor to move more easily when cold in the winter, which if you warm up you vehicle sitting a lot may make the MPG difference, other wise at operation temp is it at 30 so it makes no difference. I run 5w30 in the winter, and 10w30 in the summer. If you live in a warm climate I would run 10w30 year round

WRONG ANSWER HANS!!! It can be used in any engine. Like previously stated more so for colder climates.

On that note i have been using Amsoil 0w30 in my heap since i bought it from my dad with 60000 miles on it.

Theoretically, the thinner the oil, the better in winter, better MPG due to less viscosity BUT less protection in normal climates. If the protection was exactly the same, they would only sell and recommend the thinnest stuff available.

I require things to do.

Less protection is not correct. It is still a 30 weight oil at operating temperature. The 1st # is how the oil act when it is cold, or in the WINTER, which is what the "W" represents, ie 10W-30 or 0W-30. Both meet the requirement set forth within the SAE guidelines. Google now!

A 0W-30 has met the requirements of a 5W & a 10w-30. The better flowing 0W can reduce wear at startup, which is wear the majority of engine wear comes from.

The reason that not all companies sell a 0W oil is that it is more expensive to create a product with the broader operating range. OEMs are going lighter on required viscosities as they have discovered it is an easy way to squeek out a MPG improvement. This means that the oil is having to work harder.

If this is true, than why don't the automobile manufacturers (GM) specify 0W?

Many oems are calling for lighter weight oils, GM suggesting 5W-30 for a while now, Chrysler and Ford have moved to a 5W-20 in most of their new cars and Toyota has a spec out for a 0W-20 in most of their new cars. This includes the 2009 Tundra with the 5.7 V-8. I know this because I just switched my neighbor's new truck over to Amsoil for him. He was having trouble finding a true PAO synthetic 0W-20 and Amsoil was one of the few he could find.

It's coming. The new ILSAC spec is going to specify some fuel mileage requirements and lighter oils are helping meet that.
