Want to start using a fule addidive in my 07 GMC Duramax diesel. Heard Amsoil Diesel Fuel Additive Concentrate was good. They recommend 4 Oz. per every 5 gallons of fuel and to use each time you gas up. Any advise on this product or others you would reccomend. First time diesel truck owner. Thanks!
There are a lot of good fuel additives out there. Bottom line up front is stay away from any of them with alcohol, as this will dry things out. I have been using AMSOIL
Fuel Concentrate and
Cetane Booster since I bought the truck last spring.
With clean injectors your fuel Economy will improve and your horsepower restored. The fuel concentrate will help add lubrication to ULSD fuel. It also acts as a fuel stabilizer by improving oxidation and thermal stability of fuel.
Minimum standards for cetane in diesel fuel is around 40, depending on the company you get your fuel from. Cetane Booster is an ashless, alcohol free product which can increase your cetane levels by up to 7 points. With this and the fuel concentrate, I have noticed a quicker starting, smoother running truck. You can treat about 80 gals of fuel with each bottle based on the recommended levels of use you described above.
If I can get you some more information or a quote to try some of these products, just let me know.
Take care,
