patricia panno: I put it in my GMC Duramax, Ford 6.7 liter, and my Kubota tractor. I was truly impressed by the difference in all three.

Suneesh: I have a 2017 Chevy Cruze diesel thats done about 134k kms. Of late I got couple of error codes - P200ee nox sensor and P2457 egr sensor twice. I cleared them but they came back and then the engine check light turned on. I went to the dealer and he quoted me close to 1000$ to diagnose and rectify the problem. Before I spent that kind of money I decided to try this and boy does this thing work.

I had noticed that the exhaust was smelling different probably due to clogged dpf before and after I used this the smell was gone. I noticed a great difference in acceleration and low end throttle response specially after a cold start. Engine is running a lot smoother and revs cleaner, idle is quieter too. I have driven close to 2000 kms after using this and those dreaded error codes havent come back soo far. So glad I decided to use this before spending 1000$.

Keith: I used this on my 01 F350 and it improved my 70mph fuel from 13.1mpg to 14.7mpg. Now with that said I did also use the HotShots Stiction Treatment at the same time. Then drove it 1,600 miles across country at 80-95mph and it worked great! Highly recommend it. Best Wishes & Blessings. Keith Noneya on U tube.

Shingo Ishihara: I had have issues for my Duramax lly for white smoke quite long time. Especially, one cylinder which showed +15 in the balance rate at the start, and then +6-+8 hovering around. I replaced new cylinder head and head gasket because of leaking coolant. Then, replaced injectors and sent FICM for repair. At this point, I still had white smoke and one bad balance rate (cylinder 1). I checked the wire and replaced it. I had still the issue. I just gave this a shot since many people recommended. What a surprise!!! It was just gone within 50 miles. Balance rate is 0.0 +/- 1.0 now. No smoke anymore. I should know this before. I used diesel kleen before, but I had white smoke. So if you have similar issues like mine, try this before you go to see mechanic. It might fix!!! I will start to use edt version this product after this treatment.

Joseph Brown: Honestly I'm completely over the moon with how well the diesel extreme worked in my 2012 bmw 320d F31. Has high mileage and I want too look after it the best I can. Honestly noticed a huge power increase straight away. I've tried stp, wymns, redex, miller's products but none have come close to how this makes my car feel. Definitely a fan and I'll continue to use this product for as long as I can get it. Have stiction to try next. I think anyone with a diesel needs this addictive you won't be disappointed

ShotgunRed: Hotshots has the best product line for your diesel , when I can I order right from then . It's a lot cheaper but in a pinch I'll order off Amazon but be careful and price check.

Braveheart Randy: Seemed to work well reducing smoke and increased performance but took some time until results were obvious
