B3C Ethanol Shield Fuel Additive/Stabiliser for petrol 2-stroke & 4 stroke engines- Suitable for use in cars, motorcycles, lawnmowers, garden machinery and marine engines (118ml)

Dies what is says. I use in my xjr1300 during winter when bike can stand for a couple of weeks in-between use and it has made a huge difference to start up being instant on all 4 cylinders

Apparently my car is listed safe for using E10 petrol, even so, I still gave it a try, especially considering it's 14 years old, and I was concious of the valve seats etc.It's hard to tell if it helps protect valve seats etc, without stripping down engine and looking, but I have noticed tne engin has been running quieter (not that it was noisy to begin with), and I got the full 400 miles from the tank. They say you loose a bit of mpg with E10 petrol, which I had noticed, and this stuff had improved it.It is currently out of stock, but I will get more again, when back in.

USED IN MOWER WITH FRESH GAS AND FIRED UP SECOND PULL AND RUNS BETTER

Very good.

I bought this for emergencies were I could not get access to ethanol free petrol when filling up, it’s added to the petrol when pumping and nullifies the harmful ethanol in it that damages older classic fuel systems, the bottle has ml marks on the side in order to measure the quantity needed but has no handy measuring cup built in, though I carry a small medicine measuring cup to do the job. Other than that it does what it says.

Land rover used to make mayonnaise with water and oil mixing. We think it may have caused the last head gasket blow that cost £600 to fix. Eventually it would ruin engineAll runs fine now, no more moisture, even the mower runs better with it!

I use this for the petrol in my lawn mower. I can leave this over the winter and it is still good for the new season. It also stops the petrol corrodeing the carburetor up and protects any rubber o rings and diaphragms.

To be honest I have not noticed any difference in starting and performance
