I bought this product on the recommendation of a neighbor. I have been having issues with my diesel tractor just stalling for no apparent reason when snow blowing (winter months). I already use a number of fuel supplements whenever I have my outside tank filled, so I was not sure what was going on. I changed the tractor fuel filter and that seemed to help at the time, but then the problem came back. I tried adding a Diesel 911 type product directly to the tractor tank when filling to see if that would help and it stopped the problem cold. That is what I did throughout last winter and never had a problem. So I figured adding this product to my outdoor storage tank would likely solve my problems. So far this winter I have not experienced a singe stall, so it is working great for me. I think I will likely stop buying and adding the other products to my fuel, as this one seems to do all I need. I would definitely recommend it, as the price is very reasonable.

I paid less for 5 gals of this stuff than most places charge for 1 gal. Keeps heating oil from getting to thick to travel through extremely cold oil lines. Keeps sludge from developing in tank. Keeps things running warm and smoothly. Can't go wrong with this stuff. I have 275 gal tank and put in 8 ounces right before each and every delivery, winter and summer.

This additive will not gel when packed in snow. I don't know how cold it takes to make any changes in the fluid. A different product("4 in 1") I tried would get opaque and thick when cold ( well above 32F!!).

My heating man recommended this product to keep my above ground heating oil from gelling.I just turned my furnace on in November. We have had several 15 degree days with no problem.

The product arrived intact, and early. Home owners may want to transfer some contents to a smaller container which may be a little difficult as 5 gallon drum is fairly large. All and all, very pleased

Arrived on time but in BEAT UP METAL CAN NOT PLASTIC BUCKET. BEWARE NOT AS PICTURED ALTHOUGH CORRECT PRODUCT. May need to transfer to protect from leakage. Correction, it does have handle for easy pouring.

So happy I found this online. I have been using a product from home depot but it was always hard to find. Usually it was already into winter before it was available. Now not only do I have have a great product at a good price it's also 8 in 1.

Better then smaller bottlesNo problem so far
