Power Service Diesel Fuel Supplement + Cetane Boost

works very well thank you

I have 2 VW Jetta diesel cars. I have been using this product for over 10 years. Have always had good results with it. I also use the summer formula and 911. All good products.

Happy quick delivery and price One negative, I thought I ordered Summer and received winter. Switched while I reviewing different quantities. So I had to make another order. Sent extra money on something I did not need. I did not want to return it and go thought the hazel . Used produce for years. Truck runs great.

using 7500 gallons of diesel a week, never disappointed.

Good product. The service and promptness from this company really impressed me . Great company to deal with !!!!

2 jugs for 7500 gallons of on road is a deal

excelent

Just what our fleet needs during the cold winter months. Bulk buying reduces costs, and great shipping lead times.

I was pleased with the quick delivery.

Been using power service for years, it is the best one out there. Also the lowest prices I was able to find even with the shipping. Will order again!

Since just instruments can show exact picture I can just "tell" my impressions. Smoother engine, less noise, better MPG and being safe from cold plugging would be what I have as result of using either winter or summer Power Service diesel fuel additives.

Works perfectly in my 275 gallon outdoor home fuel tank. No need to order expensive kerosene as additive to regular fuel oil.

Been using this product for years and it has never let me down.

Excellent winter additive at a reasonable price. My truck struggles with smooth idle during cold weather and this product sure helps with it. It also helps with better MPG, prevents fuel from gelling and keeps injectors clean.

This product work great in the cold northern winners to keep fuel filter and fuel lines clear and promote easy start. Use on every diesel vehicle we have.

Very good product for summer and winter. Never go without it. PSC has the best prices and also fast shipping. Get a good product with a great price. Cannot go wrong.

I use power Service Diesel + cetane boost in -18 degrees f with no need to idle my truck at night always starts great would recommend this to anyone running in cold weather P.s I always get my product quick when I order from petroleum service company

I use this product with every fill up works great 2008 f250 6.4 powerstroke will buy from them again

Ive never seen such fast turn around time.....Ive never owned a diesel ...But I know what I need to do every winter Buy this stuff

Great product for diesel engine and fast delivery

We use it in our rental fleet of equipment. A few ounces every time they come back. It helps with who knows what our customers put in the fuel tank. PSC is great to deal with and have the best price on the internet I could find.

I have been using power service n my Kioti compact in winter for several years. In 2016 I started driving a Ram eco dieel but was not using ny additive. Since watching your video about Cummins endorsement of PS products I've been using in both of my diesels year round. The extra lubrication can't hurt and likely elps

Power service is the only fuel treatment we use it's thed best! Petroleum service company is awesome as well fast service and super pricing I'll order from them again!

Excellent additive at a reasonable price. My truck struggles with smooth idle during cold weather and this product sure helps with it. It also helps with better MPG, prevents fuel from gelling and keeps injectors clean.

It is the only additive I use in all my diesel engines. Power service is the best!!!!!!!!

Cetane boost is needed to condition diesel fuel to increase the quality of fuel in the tank. We never have lubrication or firing issues on the Genset engines we service using diesel power service cetane boost.

Use this additive with every fueling.

Will be a regular customer SERVICE is excellent

I own my own tractor trailers we use large quantities of products you offer. Prices were very reasonable and I received my order earlier than expected. I would recommend to others and have already told some of my other transportation contacts.

My wife found you wonderful to deal with and she has already recommended you to some of our friends we will be buying from you again . Thank you

Excellent product fast shipping thank you

I have been using Power Service diesel additive for the past 7 years in my 2004 Dodge Ram 2500. It is a great product, have never had any gelling issues or injector issues. Thank you PSC for having this product at such a reasonable cost and for providing fast shipment.

Starting using this product a couple of weeks ago on my 2013 Dodge Ram 2500 cummins diesel and I notice right away a difference in performance and MPG.
