AR6500 Diesel Treatment

Best Additive Ever

I've been using AR6500 for over 15 years. In my old 7.3 and now in my current 6.0. No stiction problems, faster starts and a bit better fuel economy. One of the best things you can do for your diesel, period.

Lubricates well

I don't know if it's worth it or not all I know is I put it in my tank every time I fuel and my Bosch cp4 has not exploded yet. I'm not a scientist or an engineer so I have no idea what it actually does.

Quality product at a value price.

Probably a little hard to quantify increased fuel economy claims, as my truck use is very varied. We know from research that lubricity is a critical component for engine durability. AR6500 is providing the lubricity at what is a value price when bought in the 40oz size.. The bottle design makes routine usage at every fuel purchase very convenient.
