Has anyone used "Diesel Kleen" in your PSD to increase the cetane level in your fuel and clean the fuel injection system?

It claims it cleans and lubricates the injectors, etc.
Is this product safe?

Any potential problems using it?

Thanks!

 

I use it all the time and never had a problem

 

I have used it (diesel Kleen grey bottle) many times. I put it in everytime I fill up. I only have the 29 gallon tank so I only use half the bottle each time. I began using it several months ago and immediately noticed a 1-2 mpg increase and better response. I don't think anything was used prior to me purchasing the vehicle (got with 51,000 miles on it). So I think it has helped. The grey bottle doesn't help with fuel gelling, but in W. Texas...that's not much of a problem. many on this site use it or Stanadyne. I tried both and didn't notice any difference in the two...except that Stanadyne was harder to get ahold of in my area and about twice as much. I like that I can get Diesel Kleen at Wal-mart for $3/bottle (32oz). I couldn't see any potential problems other than when I changed my fuel filter and didn't use the tubing to keep it from spilling everywhere --- it made the driveway pretty slick...almost busted my rear several times!!

 

No chance of injector oil ring deterioration or other rubber fuel system components?

 

I wouldn't think so .... at least not any more than just letting them go.

 

I will try some of that, I am pretty sure my injectors need a clean..

I'm using Diesel Kleen and I have noticed an increase in performace, excelleration, better mileage and a quieter ride. I've also tried the Diesel supplement, manufactured by the same company and a little cheaper, and I didn't get the same results. Stay with Diesel Kleen! I've had problems locating it in the local auto parts stores and found it in Walmart, of all places.

 

Diesel Supplement has less cetane improver and contains an anti-gel.

That's why you saw a difference between it and Diesel Kleen.

 

I purchased my 2001 Excursion PSD used with 34K miles on it. I just started using Diesel Kleen (White bottle) about a month ago and notice a 1-2 miles per gallon increase in mileage and alot better throttle response.

Walmart carries both kinds of Diesel Kleen, a grey and a white bottle. The grey bottle has a higher Cetane boost, up to 6 numbers. The white bottle only boost Cetane by 4 numbers but has a anti-gelling agent for cold weather use.

I've had good results so far so I'll keep using it.

 

For the two years I've owned my X, I've never run any type of additive through the tank. My mileage started to drop so I decided to try a fuel additive. I ran some Diesel Kleen through my tank and it made all the difference. The mileage and throttle response have greatly improved. I haven't tried it on a full tank, but I bet I'll be amazed. If you live down south, stick with Diesel Kleen, if you live up north try some Stanadyne if you can find it. Either way, it will save you alot money on Diesel in the long run.

 

I try to remember to put Diesel Kleen in every tank. I notice a difference when I don't use it for a tank or two. I buy it at w-mart in the big bottle so I always have it at the house. Don't carry it your cab, just a few drips will stink your interior up for awhile.

 

I run Diesel Kleen (gray bottle) every 3-4 tanks in the summer, and every tank in the winter.

 

It will stink up the interior if even the smallest drop spills, I know first hand.

 

I just tried it for the first time last week, and have noticed a quieter ride, and better cold start. With weather startin to get down close to freezing, I figured it couldn't hurt to try it.

 

The Wal-Mart in my area stocks only the Shell Rotella DFA All Season Formula. Would this be similiar to the Diesel Keen (white bottle)? Can anybody give me some more ideas who might be selling the Diesel Kleen product in Arizona? At what outside temperature should I start to be concerned about fuel gelling? We have very mild winters in Southern AZ, but I do plan on traveling to colder climates this winter.
