Synthetic oil for a Duramax???? - 1/27/2007 12:00:45 AM

I have a Duramax with the Allison and the book says to use 15-40 oil rated for a diesel. I noticed Rotella has a 5-40 synthetic oil rated for diesels and was wondering if this would be OK for my Duramax? The label on the oil bottle said it's good for Duramax, Powerstroke, Cummins and others. Does anybody know how using this oil might affect the warranty? Is this a good oil to use in the Duramax? What's the best oil filter to use?
Thanks in advance for your help........

Using the brand that you want to wont't affect the warranty unless it didn't have the correct rating code which basically all modern oils do. besides what are they going to do, send it out for analysis?

If somebody had a better answer than the one above I would appreciate it. What I'm wanting to know, will the the 5-40 Synthetic oil damage the Duramax and if not, is it worth the extra money?

Art,

If your looking for a good quality synthetic oil. Why not check out amsoil.com. You can use their 15w40 Heavy Duty Diesel oil which will allow you to drive 25,000 miles without changing the oil and the filter will last the same duration.

Their have been customers who have driven up to 80,000 miles before changing the oil using oil analysis. If you would like more information regarding this fine product, you can email me at osh599@yahoo.com.

I have several satisfied customers including a fire department that has been using Amsoil for over a year with outstanding results. This fire department also put Amsoil's synthetic transmission fluid in their Impala's to which is good for 60,000 miles under severe conditions.

This oil will increase your gas mileage and also save you time by not having to change it every 3000 miles. Did you know that most other synthetic oils still recommend the 3000 mile interval? Sad but true.

We're all hungry here and good for the self promotion, but sometimes it's still cheaper to get it from the source. NO OFFENSE!

By the way, we stopped carrying Amsoil at our shop because their "extended" drain intervals don't match up with the factory recomendations. If your vehicle is under warrenty and you go over the recomended drain interval and you have issues, the dealer won't honor the warrenty. We haven't had a problem, so we don't know if Amsoil will cover the repairs either. They DO have good products and I strongly recomend using it in your desiel.
