Mountfield MS1211 Universal Fuel Stabiliser 100ml is rated 4.3 out of 5 by 10.
Rated 5 out of 5 by from Stale fuel no more Every spring i find it difficult to start my mower and for the last couple of seasons I have used this product to mix with the fuel and it makes such a difference keeping the fuel fresh and making starting easier at the beginning of the season. I usually fill up a petrol can with 5 litres at the beginning of the mowing season and add a bottle of this to it and it lasts me throughout the summer and autumn. Great product

Rated 4 out of 5 by from Not the cheapest but .... Having just put a special offer Mountfield HP185 petrol lawn mower from Screwfix into the online 'basket' it made sense to 'prevent rather than cure' by buying this Mountfield fuel stabilizer at the same time. Others are available as they say and cheaper but it would be reasonable to believe that this is specifically blended for the Mountfield mower.

Rated 5 out of 5 by from Fuel stabiliser Just bought portable generator, using unleaded petrol,didn't know that fuel can go stale and cause problems with engine,found out that you need to add this fuel stabiliser to 5ltres ,this prevents fuel breaking down and gelling in tank,also lubricates engine when in use.
