Came super fast. Great customer service

Great to buy bulk

I've been using this product for a few years in my Heavy Haul truck but I bought it by the (somewhat expensive...) of 8 oz bottles.

It was great to finally find a bulk size(5 Gal) option that brings the cost down some. I never fuel up without adding some to the tank, you feel the difference and on the plus side I've NEVER had a re-gen on my new (2018) truck now 1.5 years old and over 160,000 k/m I believe this product helped a lot for that...

It's good to hear that the product is working so well for you Reg! It's always nice to hear a real life account from customers.

Product seems to be working
