Power Service Diesel Kleen+Cetane Boost 64 oz, Pack of 1 3064-06 Grey

Excellent product for my diesel engines. I've been using this for quite awhile. Primarily for my Ram 3500 with Cummins engine. The truck sometimes is not driven for days. But with this product it starts right up and runs smooth with plenty of power year round. I also use this to treat the fuel for my JD 3320 tractor and Kubota KX033-4 excavator. Both of these sit sometimes for days just like my truck. But they both fire right up and run smooth with all the power I need. I buy both the 64 oz and the 12 oz. It makes refilling the 12 oz bottles easy and you save a few bucks. Cool. Highly recommend Power Service Diesel Kleen. Make your life easier with one less worry. Treat your fuel!

Arrived quickly. Use this stuff a lot in my truck.

Power Service Kleen Diesel 64-ounces Jug, makes refilling 12-ounces long neck bottle, easy. Cost less in 64oz, wish 128oz were available. P-S-K-D boosts National Cetane 44 to Cetane 50, smoother torque, softer engine noise, no dark exhaust from twin pipes. Use 12oz bottle before filling Ultra-Low-Sulfur-Diesel in 2022 GMC Sierra 1500 3.0-L i-6 Duramax engine pickup truck 24 gallons tank.

Good stuff.

I have never had a fuel issue with my Sprinter adding four ounces of this with every tank. Also helps to stabilize the fuel if the van isn't used much in the winter.

Great product great price

been using in my tractor and zero turn diesel. seems to keep running smooth and more power

After research, lubricity is critical for diesel fuel systems and engine components. I use every fill up of diesel. Price is ok

This stuff is great. It cleared up my boat's smoking problem very quickly. There is no more sheen on the water after idlying into the slip.

recommended for my diesel by my brother in law who is a gmc mechanic for years

Use this for my 2015 Passat TDI. Definitely notice improvement in fuel economy. I wish the bottle was easier to pour / dose. If you spill, the smell is very strong and lingers for a while. But that’s probably a user skill issue.

Good product

Buyer beware!!! Do not buy from this supplier. They shipped this product to me by Purolator. Purolator does not advise when shipment will arrive. They came to my home when I was out and left a sticker on my door. Apparently, the shipper required a signature so, Purolator could not leave the package at the door. Instead, they returned it to the nearest Purolator depot, 104 km away and I had five days to pick it up. It cost me more to retrieve the package than it was worth. As well, Purolator could not tell me what was in the package or who shipped it. Never again. Apparently, I'm not the first Purolator victim.
