Value for Money

Best stuff on the market. Good stuff, but don't give it the sniff test. You'll regret it.🤪

Wow! Actually works van does not rough idle and flew through mot with no mention of emissions like was the problem last year…buy it! But DO NOT spill it…it STINKS, wear gloves when using and don’t inhale fumes!

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.

UK van driver here I 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 smoke Love 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.

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

Super fast postage, used it only once so far but seems to do as it describes

Muito bom para carros antigos movidos a Diesel S-500. Limpa bem a linha do combustível e o recipiente já vem com as medidas a serem colocadas. Vale a pena investir.

We have found our RAM ecoDiesel to be a little particular about the diesel we put through it. We had no trouble at all with the two diesel stations we usually use, but after a tank from a supplier we don't usually use but had to in a pinch, we noticed changes in the horsepower and the particulates in our exhaust. It took a few tanks from our regular diesel provider, and the use of this clean and boost, to get our engine back to normal. It's running normally again, and we are not having issues with heavier than normal particulates in the exhaust. We are much more particulat about the quality of diesel we put in it now, but still use the clean and boost every so often just to be "clean" things up a bit. If you have issues with the quality of your diesel, this product from Hot Shots' really helped us out a lot.

I usually don't believe in this stuff much, find it's mostly a waste of money. Had an old diesel sit for 9 years, ran rough as heck obviously on its old stale diesel fuel. Tossed half a bottle of this in, and filled the last half of the tank with fresh diesel and it runs better than when I parked it. Definitely buying a few more of this stuff.

Just purchased a diesel and wanted to keep it running well. This stuff works amazing, and can feel the difference. I would store it in the bed. Bottle leaks some and smells strong. Would not recommended storing in cab. Size of bottle is good for 1-2 fuel ups.
