The 0W-30 will be fine. Have you had synthetics before? The high detergents in the 0W-30 will do some serious cleaning inside your motor, therefore I recommend a WIX, K&N, or Amsoil oil filter and change it every 3,000 miles for the first 10,000 miles. If you want extended intervals, then I would take an oil sample at the first 6,000 mile interval if you wheel a lot. If you do mainly highway driving, then i would take a sample at the first 8,000 mile interval. I run the Amsoil 0W30 and change mine every year, which is only about 6,000 miles a year.

I've been Mobil1 5w-30 for the past 2 changes so this is the 3rd. Alway used the Mobil1 filter and changed at 5k intervals. Just can't pull the trigger on the AMSoil yet with the price difference, but maybe someday.

I use 10w30 mobil 1 when it's hot, and 5w30 when it's cold.

Amsoil is a good company and they have other facets that make them unique beside just selling lubricants and filters. They also sell nutritional supplements, water filters, organic fertilizers, and other random household products. Everything they sell is top notch However, in response to your post, it is difficult to justify the cost of AMSOIL unless you are taking advantage of Amsoil’s extended drain intervals. If you are doing 25,000-30,000 mile drain intervals, then yeah, you are saving money while prolonging the life of your engine. It’s truly a win/win situation. There is a small fuel savings just by running the 0W-30, especially at the current cost of fuel. In my Dodge Cummins, I run the Amsoil HDD 5W-30. As a dealer, the 5W-30 is costing me $7.65 a quart. Although, the minimum suggested retail price is $9.95. It takes nearly 14 quarts to fill my truck. Rotella is somewhere around 3.95 a quart.

Let’s do a cost comparison:
Amsoil 5W-30 (change oil once a year) = $107.10
Rotella 15W40 (change oil 5 times a year) = $276.50

Savings: $169.40 per year and resulting with a cleaner engine, longer lasting engine, and additional fuel savings by the using the 5W-30 weight vs. the 15W-40 weight.
