Fuel Stabilisiers

[tezzer]

Having acquired a rather nice GT550A Suzuki, I have been reading up on the horror stories of Ethanol diluted petrols dissolving carb and engine parts, anything rubber / brass / alloy etc. SO invested in a bottle of fuel stabiliser, to see if it offsets the damage potentially caused by using modern fuel in a 1970's engine.

Anyone else bothered to try it f so, did you notice a difference after a lay off ?

Never bothered personally & have had 1970s British cars start on the same fuel after nearly 5 years.

Ive read plenty about this but not experienced it myself, it does take some while for it to go off in such a near ideal container as a petrol tank, my Hayabusa has been in storage since April 2013 and still fires up on the button with the same fuel!

I drained the fuel from my LC and will be draining the fuel from the KR/TZR next week but thats because im more worried about the tanks rotting out rather than the fuel hose etc perishing.

This is far better than a fuel stabilser IMHO...great article on this stuff a few months in CMM mag.

I've never had an issue with either the NS or the MTX for the past 15 years. I do drain the carbs and tank each winter and spray inside the tank with WD40. No rust in the tanks, no issues in the carbs. Both look new internally.

If you use some premium fuels, they don't - or didn't contain Ethanol. Esso was one that didn't but that might have changed.

Edited to add, both bikes are Honda. Suzuki might be different but I doubt it.

Because it attracts moisture ,especially ethanol fuels, this then condenses and turns to water, sinks to the bottom of the tank and rots it, particularly when the bike is left on the side stand long term,you'll notice the rust appearing just below the fuel tap...just like my old LC tank, my mates LC tank and my others friends LC & several KR1 tanks..!

Decent, solid or NOS fuel tanks for 70's/80s stuff can cost serious money as they are scarce for just that reason.
