FPPF 90188 8+ CETANE IMPROVER 32 OZ. BOTTLE, TREATS 250 GALLONS OF DIESEL FUEL PER BOTTLE

I put 2 ounces in the tank of my 2014 BMW 328d and went to the nearest "Wawa" to fill up diesel. It is about 2 mi. away. After filling up I made another mile and had to stop on a traffic light in order to make a left turn. When I stepped on the gas pedal to depart the car picked up unusually fast. It felt a lot more powerful, just as at least 20 more horsepower and abundance of torque....The engine felt like it awakened from a long sleep and it has been like that ever since as long as I put the 2-3 ounces of the additive. I have tried multiple diesel additives but this one is the " cat's meow". Nothing else has given me that noticeable and energetic boost of performance. My guess is that the car needs high cetane diesel - something available in Europe but not present in US. I would 100% recommend it to anyone who drives a high performance German diesel car.

I have been using the 8+acetate Improver along with the Total Power in my rebuilt 7.3 diesel for about 5 years now and my F-350 runs great. My truck does not smoke and pulls my 17,000 pound Fifth-wheel with ease. I received my order in three days and I’m pleased with the product and the seller.

My wife has a Volkswagen Jetta TDI Cup Edition. We both like driving fast so I ordered this for her. This stuff blows any cetane booster you can buy at the auto parts store out of the water. An extremely noticeable improvement. Our TDI Cup is no slouch, but this makes it a lot faster and run way smoother.

This is the best additive for the diesel owner. Cetane at the pump is not sufficient for a complete burn and will also result in difficult cold weather starts. My diesel mileage has increased from 18 to 23-25 with this product. Yes, I do use the on-board computer for this stat since I have checked it and found it to be as accurate as I can get. I have used it for 2 years and in all conditions. I have a 2000, 2500, 4x4. I have +70 HP injectors, 4" pipes from turbo to tail (not the stock crimped down after-turbo adapter). Injector pump is the Blue Chip stock injector pump (with upgraded guts and Fed-Ex timing upgrade). No chip. Stock air filter is the best per independent tests. I also run the 3Pc Pulse Flow Manifold and the Aurora 3000 Turbo. All this stuff is really just upgraded stock parts which restrict the Cummings. I ran all the upgrades with no additive to get the 18. I don't hot rod it. I baby the throttle. This is all in town driving. On a rare occasion I will travel to the next town 15 miles away but will not bother to tell you how high that mileage is because you won't believe it! The lubrication additive I use is Diesel Kleen. I will never run my rig without these products!

This product is ok, but not great. I wouldn't buy it again. It is also cost prohibitive because of how much you have to use to achieve an increase in cetane. There are better boosters out there where you can actually notice the improvement in power and economy, this product did not deliver either one for me.

Excellent product. Use this if you have a boat with a Diesel engine.

I swapped to this after using a less experience brand for 6 months and my mileage decreased. Does not perform as stated.

I have an 04 Duramax with known injector failures, I run this stuff at a 1:1 ratio with FPPF Total Power and mix it at their medium mix level. Completely stops all injector clicking. Roughly 1 MPG increase. Will never run a tank without it.
