Drive a 2010 ZDX: when running King Soops premium, the car pings. Put this stuff in, and no pings. Gotta dig that.

I've been using in my new 3.0 eco diesel from the beginning bc the present leaders are trying to kill the diesel engine with their regulations on lubricity in diesel fuel. Use it regularly to keep your high pressure fuel pump lubricated.

I always use diesel all in one every time I full up my RAM 3500 because you never know how dirty the fuel is coming from the pump and knowing Amsoil test all there products to exceed all standards and keep my engine running for years to come.

Did not really notice any difference, was hoping to at least see a1 to 2 mile per gallon increase in fuel mileage.

More power, response and money saved on fuel economy!

Simply put - the best diesel additive available.

Simply put - this is the best all-weather product available for all your diesel powered machines.

Big Bird, the ford tractor, loves this stuff. It's really running great w/o any black smoke. Lots of power and only gray smoke.

Great product. As usual, AMSOIL has produced an amazing product. I have seen improved mpg. It’s a slight improvement, but none the less. I went from 11.5 to 13 mpg. My engine sounds solid. It runs great. Seems to be a happy truck. I do like the long skinny necks on the bottles. This makes for an easy pour into the fuel tank. The size is perfect for storing a couple bottles behind the rear seats.

Noticed a significant change in engine idle, was much steadier after just one dose.

I’m impressed with the boost in MPG and performance as it’s a difference that is apparent.

I always thought these additives are most likely beneficial, what I didn't think is it would make a noticable change. Ran one bottle and noticed smother idle and snappier acceleration from a stop. 05 dodge ram Cummins, 170,000 miles

It has help my fuel economy and I don’t worry about my fuel gelling up or clouding over

I have use this product in my F250 and diesel tractor and am more than satisfied.

This diesel additive is awesome I definitely notice when I put it in

I use this with Mobil Diesel efficient diesel fuel at every fill up. With newer diesels you cant be too clean when it comes to fuel. Never had a problem with gelling in the winter. Ive seen -30 here and north of here with no issues. Car runs like it has new intake and turbo. Very happy

I have used Amsoil additive for my diesel truck for years, but normally am not in a 0-20F weather for very long so I never really used it before. I order some for a recent trip and it got down to 8F and I had no issues. I also bought the diesel All In One to add after each fill up, after giving my tank a shot of the "Cold Flow". Truck ran great as always and I recommend using it, if cold weather is in your future. I also was at a gas station and their pumps could not pump the diesel from their tanks, I had to go to their other station normally for semi's as their pumps were working for diesel, the attendant told me it always happens when it get real cold. Should have suggested "Cold Flow" :).

I've gelled up multiple times while using the white bottle (starts with P) and clear bottle (starts with H). Since switching to cold flow over a year ago I have not had a problem. Just another rock solid product from Amsoil.

Im sure the product is above the average as all Amsoil products, but the bottle is an odd size and only treats 20Gal at this mixture so for us 30 gal tank owners, a clear bottle or one with a see through strip to see the 1/2 way point would be great. Or get the measureable bottle like others have

Use this in my 21 silverado 3.0L diesel, very good product.
