Absolutely.

Accept that it doesn't.

Interestingly enough, I dyno'd my 07' Duramax recently with a good dose of the Amsoil cetane boost in the tank. The truck made approximately 20+ more rear wheel horsepower than a couple other guys running similar setups. The truck dyno'd @ 451RWHP with a PPE stage 4 tune, full exhaust and a modded stock airbox. Several of the other trucks delivered between 380-430 RWHP with similar tuning.
Was it the cetane boost difference>?
The vehicles I've put it in have all run noticeably smoother and have better responsiveness. I have also seen a bump up in MPG running higher cetane fuel too...whether it's Biodiesel or just cetene treated #2.
One thing is for sure, we need better quality, higher cetane fuel here in the US !! We are always several years behind European automotive technology though !!

Who sells a bigger engine to fit my car?
Or who sells a car with a bigger diesel engine for the cost of a cetane booster..

i know Ford makes a cetane booster but i am not sure if it would work good in a tdi? Dose cetane booster go bad if it sits for a long time?

You could buy a older VW suv when they put the V10 tdi.

Thumbs up

Found a new made in Usa diesel additive called "Boost Plus Diesel" that has a low price of $16 for a gallon that treats up to 1000 gallons.
That amounts to 24 cents per 15 gallon tank! We can get 66 fillups out of one $16 gallon jug. That is amazing. With the increase in fuel economy, and the amount it displaces, it will more than pays for itself per fill up!
Specs seem terrific, so I had to give them a try. Just ordered some and will give a review once I hit around 500 miles of testing.

Not to be discouraging but realistic...

Unless my math is off, 128,000 fluid ounces (1,000 gallons) to 128 ounces (1 gallon) is a 1:.001 ratio. I find it difficult to imagine anything added to diesel fuel at that small of a ratio could be of any benefit to MPGs.

Back in the day, I kept meticulous records (Excel Spreadsheet) of fill-ups (topped off) tank after tank for about 300k miles (when I retired). I was driving slightly over 36k miles per year. The MPGs varied tank after tank which was mostly due to driving circumstances. I had graphs reflecting ounces per mile of consumption, MPGs, Liters per hundred miles, etc. So, even with those detailed records, I seriously doubt that I would have noticed the effects of an additive of 1:.001 ratio.

I believe your PD engine will not notice 1.9 ounces per 15 gallons.

At $2.75 per gallon, the $16.00 could buy you an extra 5.8 gallons of fuel. At 45 MPG, you could travel another 261 miles.

Results will be interesting, but do you have base data to provide a comparison?

This subject just came up in another thread and there's some actual data, not comprehensive, but something that one can work with. It's caught my interest (need to keep reading in to the thread to get at the meat that matches this subject).

Has there ever been any discussion in the past around here as to WHY the U.S. only requires a minimum of 40 cetane in diesel fuel?

40 Cetane requirement got done by the oil lobby, our tdi's need 45 or higher to have a better burn and correct combustion, driveability, etc.
Thus, the need for a cetane booster. It makes each fillup cost more, but we can at least get the vw designed 500,000 miles before piston overhaul. Just be sure to shop how much each additive will cost per fillup when comparing pricing.

Kind of a solution looking for a problem if you ask me. If you look at the Infineum winter fuel report the numbers are encouraging. It isn't the end all test but at least has some factual data about random testing. East and West coasts show extremely well. Midwest had some low numbers but still had a mean in the 47 to 48 range.

The fuel quality is improving and I really don't see a need for cetane additives unless you are consistently getting some fuel that runs badly in your car and you can't change sources.
