Id like to know what additive(s) yall are using and why?
Iv been using PS in white bottle and Marvel Mystery since Iv had the truck and it works great for me.
Im just curious if another type would work better.
Thanks.

 

Stanadyne all the way.

 

Stanadyne is definately the best IMO but it aint cheap either

 

i use a product called gen49. It is a cetane booster, it works awesome, especially where you get winter fuel. My engine dosent clatter when using it like it does if I run fuel alone. I also noticed a mileage increase after the second tank.
I believe that name of the company that makes it is called powerup,

Power Service white or grey bottle. quiets down rattling....actually totally eliminated it.

 

Power Service white, switching to gray because I am not worried about cold weather gelling. (I just noticed there was a 'gray' bottle the last time I went to buy it. )
