Use evey fillup. A little goes a long way. This company is legit. They do the science work to bring out the most of every product they produce. I've done the research and take it from me you can safely settle with HOTSHOTS products. Science proven! I use in my Ford 6.7 Powerstroke. It's important to add lubricity to preserve your high pressure fuel pump. American diesel lacks the lubricity now due to low sulfer requirements. BOSCH makes the CP4 fuel pump. In Europe their fuel is better. Here in the US we need to add lubricity. 2% biodiesel is actually the BEST lubricity you can attain! Many fuel stations use 5% bio-diesel. You'll have catastrophic fuel system failure if you don't use lubricated fuel in your 6.7 Powerstroke. That's a 7-10k bill! No joke.EDT gives at least 5 benefits. Next best reason to use this every fill up is the added cetane boost. They figured out how to get the most performance boost per dose. It makes a noticeable difference in my VW Jetta TDI. YOU CAN FEEL IT by the seat of your pants.Highly recommended. It's my go to.

Ran this in my 2014 3.0 TDI, on just the first tank I noticed immediate improvements to my idle quality, cold starts, and fuel mileage. I loved this so much that I bought two more and even run it in the diesel heater for my garage now.Weird downside though is that the cap is really bad at sealing after opened. Ended up dumping 2oz into my door pocket trying to store it there..

Phenomenal product. Keeps my 7.3 starting first crank on even the coldest days. Easy to measure and a great price.

This is my new go to fuel additive. I reviewed several products and this product won out because of its ability to help with rust development over time.

I've been using this product for a few years now, and it has significantly improved my BMW 335d M Sport. The engine runs smoother, the mileage has increased, and it's much quieter overall. After using it, I was able to eliminate the smoothness error on cylinders 3 and 6. Since then, I follow the instructions and use it with every fill-up. My diesel now has 147k miles on it and still runs like new with 44 MPG highway and 32 MPG combined.

I use this on every fill. I feel like I get about 1 mag better with it. So really cost me nothing to use
