Fuel Additive

[gauge]

I was wondering what kind of fuel additive yall were using on yall's 6.4's. I haven't used any yet, as I had a friend who went from the 6.4 to the 6.7 and stated he had never used any in his 2008. Just wondering what the consensis was for the forum.

The only additive I would use is fords cetane booster that is it!! Also make sure you change oil every 5k or 200 engine hours!!! your rockers will love you for it!!!

I use Power Service Diesel Kleen +Cetane Boost in the summer and their Diesel Fuel Supplement +Cetane Boost in the winter.

Opti-lube, before that Diesel Kleen. I would definitely use an additive!

Used Diesel Kleen first and then Opti-Lube and now back to DK because it is just easier to come by.
