RBP RBP-80001HP 16 oz. High Performance Fuel Additive with Cetane for All Diesel Engines

This product has worked really well in my 97 Dodge 2500 5.9L diesel engine. It get about 6 fill ups to a bottle. I have a 32 gallon tank. My diesel mechanic always tells me how clean my injectors and ports are for a diesel engine with 300,000+ miles and Calif. grade fuel. Cheaper than the rest of the products out there

Eliminates smoke from tailpipe on a 2006 duramax with 185,000 miles. Power increase and economy were slightly better.

overall the product seems great, it was delivered fast and its a additive so it is what it is.however with that being said ive heard (no hard facts) that some motors do well with additives and some with out.i feel that running this product in your diesel shouldnt hurt anything and all you can do is try. the ultra low sulfer diesel that we are now using has alot of downside so it may not be a bad idea to try this, and see if you notice any difference. most likely you wont physicaly notice but some extra lube never hurt anyone :)

I purchased this product to help my truck run smoother and start easier. It did just that on after the first tank. Quick delivery and easy to measure spout. Well worth the money.

All of these additives are tough to evaluate. Claims for higher mileage and improved everything are tough to quantify in everyday driving. That said, I like the mix ratio as this bottle will mix with a lot of fuel, meaning its not overly expensive. Also, the pre-measure chamber on the bottle makes adding what you want/need an easier exercise.

The additive totally quieted my Cummins down and after an expensive injector change, I've been trying all the big name additives. It was after the 2nd tank that I started noticing smoother running and the Cummins shake when you turn it off actually calmed a little as well. Mileage hasn't changed but the piece of mind I get from running it seems priceless.

Been trying several cetane additives for my Ford 6.4L diesel. Difficult to find any improvements or better mileage. Will not purchase again.

I would like a replacement of the bottle. I received it and I have picture of the bottle showing only 13oz in the main part of the bottle and 1oz in the measured nozzle with the seals still in tact. This stuff is too expensive to not get the full 16oz. I would like to hear from the company in this matter.
