Power Service 3025-12 Diesel Kleen+Cetane Boost, 32 Fluid Ounces, 12 Pack

Used since new in my 6.6l Duramax and runs great

'Endorsed by Cummins' is why we tried this fuel supplement in our L9 powered RV. According to our fuel computer, our fuel average MPGs increased from 11.2 to 11.8! We add it at every fill. Our tank is 150 gallons so we usually fill and take on approximately 100 gallons so this is the perfect size to dump in without measuring. We buy a case at a time. Also benefits our diesel generator and diesel hydronic furnace (Aqua-hot). Noticed a huge difference in the annual Aqua-hot fuel nozzle change. After 1 year the nozzle still looked new & clean.

I use in every tank of diesel in my bus/rv. Raises cutaneous levels and keeps your system clean. Would never fill my tanks without it.

This is a nice box of Diesel Kleen. But it’s not the 32 ounces. These are 26 ounce. Still a good deal, as you’ll pay $10-12 per for the 26 ouncers. But the listing is wrong. It’s the same as kissing spmeone when the bar is about to close. But when the lights on, that person didn’t look quite as good as when the lights were off.

A must if you want the top economy and performance from your diesel, especially if you own a European built diesel. Pays for itself with better fuel economy. I use it in my 2009 Mercedes E320 Bluetec and my 2009 GMC Sierra Duramax. First rule of Diesel fuel..stay away from Bio-diesel. I know it is a little cheaper, but your MPG is 1 to 1.5 less. Use full dino diesel like Shell, Exxon, BP etc. Next, US diesel mostly contains a minimum of 40 cetane. My 2009 Mercedes is a European built diesel. In Europe, the minimum Cetane is 50. So, to get my Mercedes to run correctly and stop the engine light from coming on, I use a double dose to get the Cetane rating from 40 (US) up to 52. My GMC does not require the extra Cetane, but it does increase the MPG when used. The price on this 32 ounce, 12 pack is the best I have found!

Really, the product itself is 5 stars and I have been using it since my Duramax was new, almost 19 years ago now. I usually was buying at Walmart but saw they went to 26oz. bottles for the same price as the old 32oz. bottles. Sigh. So I tried this 12 pack because the ad still says 32oz. Got a 12 pack of 26oz. and hopefully they update the ad and bottle pictures soon. But the price was a little better than Walmart and I will use them. Interesting that the label still says "treats up to 100 gallons" but I really don't think they changed the concentration. But I will continue to use it!! It is much cheaper to buy the larger containers but either you have a way to carry them (I don't), or you transfer to smaller bottles. I did that for awhile but it's messy, very smelly, and somehow always spills and gets on you. So I buy the smaller bottles.

Great

Best price anywhere. Less than half the price of the exact same bottle at my local auto parts store. This 12 pack will last me for well over a year. Don't fool yourself by thinking you'll find a better deal anywhere else. Save your time, fuel and frustration and get it here. The product itself works as advertised. For me, not a noticeable mileage increase, but the truck definitely runs smoother and I've noticed the starts are not as rough when I run this. Very pleased overall.
