Skeptical when I ordered this additive, however, after a month of use I AM NO LONGER IN DOUBT! A very noticeable difference in engine sound, acceleration and a reduction in black smoke. This stuff is INCREDIBLE!! Product arrived in specified time, with the bottle contained inside a plastic bag cushioned in brown paper inside of a taped box. No damage and I anticipate future orders of the same for 2010 F350 6.4 diesel dually! RECOMMENDED!

Cured MBZ240D

Reviewed in the United States on November 12, 2023

Size: 16 Fl. Oz.Verified Purchase

The Hot Shot Diesel Extreme Clean and Boost restored a smooth idle on my Mercedes Benz 240D. The product cleaned the diesel injectors and the missing disappeared. Other popular diesel injector cleaners had not worked.

I tested the car on a long, steady climb. Before treating the car with the Hot Shot product, top speed was 47 miles per hour. The car has only 65 horsepower. After treatment, I got up to 60 mph. I am sensitive to the feel and sounds of the old Mercedes and I could tell the clogged injectors had been unclogged. The idle is smooth regardless of the ambient temperature.

Reviewed in Canada on October 7, 2023

Size: 64 Fl. Oz.Verified Purchase

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$.

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
