2011 Duramax and Fuel Additives

Hey everyone,

I see alot of people running fuel additives etc for their older duramax's but have not seen any postings on if anyone with a 2011 is running any. I asked the dealer and he said its designed to not need it but never said don't.

Anyone with the new Duramax got any thoughts?

New to diesel world so looking for advice.

our company uses BG 244 at every oil change...a bit pricey, but the stuff cleaned up my 07 pretty good after a couple of bottles....

You dont need to use an additive, but IMO its needed.
If you do use an additive read the product label & make sure it doesnt contain alcohol & wont harm the DPF.

I notice a big difference in the trucks performance when using an additive vs not using an additive.

For my own reassurance, I use an additive on every fill up. Im not relying on the fuel stations additives.
Specially in the winter time.

First off living in cold country you are going to want to run something if nothing else in the winter to keep the fuel from gelling up. Many folks run additves all year round to keep their fuel system clean and lubricated. Remember, ULSD doesn't have the lubrication properties it once did. Further more, it contains the bare minimum cetane required by the govt. Our trucks run better with a higher than 45 ppm cetane, most fuel has around 40 ppm. When you increase the cetane level you are improving combustion. Improve combustion and you have faster starts, smoother idling and less exhaust because the fuel is burning more completely.

Based on that, I run AMSOIL Fuel Concentrate and their Cetane Booster in every tank. They also make a cold weather formula called Fuel Concentrate with Cold Flow. I have tried many of the popular ones that are available today (Stanadyne, FPPF, Racor, Diesel Kleen, Power Service) and I have had the best results from the AMSOIL products. The combination of these two product have improved my starts, responsiveness, idling and fuel economy. Plus I have a little peace of mind that I am doing what I can to help keep the fuel system and more importantly the injectors clean and lubricated.

If I can answer any questions about the products I mentioned above or something else from AMSOIL, please don't hesitate to ask.

Take care,

Yes AMSOIL products are safe for all diesel applications. If I can get you some information or pricing, please let me know.

Looks like it is just short of one bottle per tank of fuel (one bottle treats 40 gallons). Do you use it on every tank of diesel?
