Hot Shot's Secret P040432Z Diesel Extreme Clean and Boost - 32 fl. oz. by Hot Shot's Secret

Very good value for money as bottle got enough for 15 to 20 tanks of fuel

UK van driver hereI have a little Fiat Doblo with 1.3 Multijet engine. Used to smoke alot on cold startups and idled rough for a few minutes. Poured the recommended dose of hotshots and viola.. Instant improvement mate.. smoke gone. No rough idling.. engine happily fires up in cold January mornings with 0 smokeLove u hotshots ❤

Bought a new high mileage suv.Wanted to ensure the system was clean.I also repaired the swirl flap but can't say I'm having any issues.In fact, the engine's pretty damn smooth.

Helps save fuel does the job very well

I had some issues i think now were caused by using supermarket diesel. I tried a few other cleaners but this one seemed to actually make a difference. Now I recognize the smell when i fill up at Esso I think the difference is they add cleaner while supermarkets skimp on that so are cheaper. I'll just use Esso in future. I've added what was left to some diesel i've got in reserve for storage as its supposed to extend the life significantly.

Golf GTD runs smoother, quieter, and more responsive adding about 10% onto miles per gallon. Super stuff.

Used on my ducato van gave me more mpg would recommend

Good product
