Best online purchase I have made

Questions were quickly answered before purchase. Price was great. Received items quickly and packaged well. They threw in a t-shirt, kit kat and a nice hand written thank you with the order. Parts were perfect and I'm on the road again. Great job. I would order from them again in a second if I needed anything. Thank you DPC!

Thanks for the awesome review David!

Fuel additive results

Actually to be perfectly honest I haven't tried the Lubriguard yet, I have used the Ultraguard and the warm weather blend and I can't really notice much of a difference between the 2, BUT, having said that I do like using the product, I just came back from a BC road trip, did a fair bit of driving around on the Island, I drive a 2008 Silverado 2500HD Duramax and from what some other people are claiming for fuel mileage my truck just never seems to do as well, it is still good though, I have a 98 gal aux. fuel tank and with that full, 4 people and luggage I am easily over 9000 lbs, ( I weighed it with the aux. tank and box empty it was 8000 lbs), 2 years ago we took the truck to Vancouver Island and my fuel mileage (hand calculated) was 21 to 23 mpg imperial gallons with one tank in the mountains reaching almost 27, this year with the Stanadyne my worst tank was 23.25 mpg and my best was coming back from Golden BC to Medicine Hat AB I hit 29 mpg on that one tank only, I haven't done any close calculating yet but my guess is 25 average. Can't complain with that. Thanks for a good WORKING product.

Hi Abe, Thanks for taking the time to share your experience. That information will be invaluable to other people looking for a quality additive. Thanks for all your support.

Just what I wanted

Product worked just as I'd hoped! Truck is running smoother and fuel economy is back up to what it was before. Great service and delivery was super fast (next day).

I'm glad the additive is helping you out Reg!

Great to buy bulk

I've been using this product for a few years in my Heavy Haul truck but I bought it by the (somewhat expensive...) of 8 oz bottles.

It was great to finally find a bulk size(5 Gal) option that brings the cost down some. I never fuel up without adding some to the tank, you feel the difference and on the plus side I've NEVER had a re-gen on my new (2018) truck now 1.5 years old and over 160,000 k/m I believe this product helped a lot for that...

It's good to hear that the product is working so well for you Reg! It's always nice to hear a real life account from customers.

We are very happy with service
Thank you

Thanks for your business Anthea!
