Fuel Stabiliser

[Gimme5]

Do you use fuel stabilisers? Does it make any difference? I mean if you've got 460L and fish around the bay and you keep topping it up every 2-3 trips, there's bound to be a lot of stale fuel accumulating in the tank. I've been using Stabil Marine every time I fill up but it gets pretty X if you've got a large tank. Any contacts for economy sized quantities as opposed to the tiny little 236ml or 32oz bottles? Thanks.

Never use anything, never had problems.

Ask your local parts outlet for a carton buy on the small bottles. Hit them up for the usual less 25% or thereabouts. Probably about the same as they would offer to a trade account and even better your paying cash as opposed to a trade account running them out to 30+ days. Win win.

I swear by STA-BIL

Never used it and never had any fuel related problems. I keep my tank full to try and avoid condensation and always have from standard 2 strokes, four strokes and Opti's. Sometimes the boat has gone up to 3 months without use.

I use fuel doctor. Supercheap has the big bottles on special
every now and then and works out a lot cheaper than stabil.

More economical - 1 bottle treats 485 litres or about a tank in your case.

They had a stand at the boat show a couple of years ago and I remembered they said they will sell direct to the public if they gave their office a call. Not sure whether they still do. I think FD is more a cleaner than a stabiliser but I stand corrected.
