Comma DTOX400M 400ml Petrol D-Tox

Good item it helped me

Used this a number of times and it does make a perceived difference in how your car behaves i.e. sharper and more responsive

Easy to use and gives an instant increase in power. Car idles much more smoothly and revs beautifully.This was after a full service and a change of spark plugs.Even once the product is long gone from petrol tank, I can feel better acceleration and quieter idling.Tried other fuel system cleaners in my other cars, but this is the best so far. And cheaperBought another bottle to use in 6000 miles time !

Following recommendation, tried this on my Skoda Fabia 1.4 16V, which was starting to use oil. Also switched to Comma 5W30 fully synthetic oil and cleaned the breather pipe to the air-filter housing. Car now running as well as ever at 116,000 miles and regularly returning 55mpg on a run.

It's the best stuff for yr petrol engine . It brilliant I use in on all my family car six of them it the best stuff

Excelllent product and good price.Thanks.

E ok

I wanted a fuel-system cleaner containing polyetheramine, so bought this. I hope they haven't changed the formula since I last read the MSDS. Historically I've always had extremely good results with this, and have saved ultrasonic cleaning of injectors and new EGR valves/lambda sensors etc. in the past. This time I've put it into a Ford Capri to make sure the fuel tank and lines are clean, and also to get rid of varnish in the carburettor float bowl and anything clogging the jets and accelerator pump. The car was running quite well anyway, but so far it seems to be working, as there's definitely a slight improvement in cold running and warm idling.
