H20 issues in fuel.
I seem to be having issues with H2O in tank excessively in my 1996 svx. Causes ruff running, intermittent ruff idling and esp. in 4th gear under low rpms. going up a hill. Using additives helps, but doesn't last long, only a tank or two. Tank seems to seal properly as there is vacuum upon removing gas cap. Any advice would be helpful.
Gas in Connecticut has 10% ethanol and anti-pollution additives. I am running 93 octane. Doc 1996 SVX Brilliant Red #765 "Gold Digger" |

Re: H20 issues in fuel.
Couple of things:
1. Are you sure it's H2O in the gas? 2. Have you tried changing gas stations? 3. When is the last time you changed your fuel filter? (miles covered since last change) 4. When is the last time you changed your spark plugs? (ditto) -- 4th gear/low rpms/up a hill is putting a lot of load on the engine, which will cause a old/fouled plug(s) to miss... -Bill

Re: H20 issues in fuel.
Water in fuel is extremely unlikely. Ethanol shouldn't affect drivability unless something else is amiss. I think the cause of your problem lies elsewhere.

Re: H20 issues in fuel.
Be careful using additives with ethanol, they could make matters worse. Attached is a link with some compatible additives.
