Fuel Right is the one you want. I think it's available in UK. You will think the motor has just been serviced.

Hello

To your question yes,it would be fine I have used it.Read the instructions though.Also Sea Foam is pretty good stuff and can be obtain from eBay.

If your engine is oil injected even better.

Is there a chance of stripping the oil from the inside of the cylinders or does this stuff burn fully?

Must admit I've always been sceptical & there's a lot on the net about adding it to the petrol. We used to use it in the 70's by tipping an eggcupfull into each cylinder, spin over/kick over a couple of times (plugs out), leave overnight then spin engine on starter (or kickstart) before refitting the plugs & starting.
Fifth Gear had a play with it & this is what they got. So I'd suggest the jury is out (unless the 'Italian tune-up' cleared a lot out!)

Could be true.
I've always used Evinrude 2+4 fuel conditioner. No idea if it works, it claims to disperse water in ethanol

Without getting bombarded by legalities I was told by someone (expert in the oil industry) that many of these products are a rip off. He did however recommend Fuel Doctor Partners which Ive now been using for the last 4 years.

Ive also used saltaway (not a fuel additive) for around the same time to flush my outboards Salt-Away UK &EU - Home which helps look after the whole outfit.

Stupid question, can these also be used in 4 strokes. I am after an injector/ fuel cleaner having just had it all professionally cleaned, I want to keep it that way.

I use an additive all the time in my outboard fuel..... Pour gallons of the stuff into the tank in a year....... It's got a funny formula sounding name......

TCW3!


Joking aside my personal experience is that a lot of these things seem to be a bit of a placebo. Only one I ever used which actually did something was a diesel cleaner you sprayed in with the engine running. Worked by making it backfire and the resulting pressure pulses shook the soot out the EGR valve.

It did appear to work. (and apologies if you were the car behind me that got covered in 200,000 miles of accumulated EGR soot as I drove off after the application....
