Default Re: Water in Fuel Light WIF warning is on.

Any biocide designed for diesel should work. Most only need 1oz for 20 gallons or so. There is minimal safety concerns with that amount of additive.

You do not need to use a biocide continuously. If you are having no symptoms, and your filler cap has no microbial build up, you do not likely need any. The occasionally dosing with a new tank of fuel cannot hurt though.

Keeping your tank completely full during storage, and filling from well used stations is the best method to prevent microbial growth. The fungi/bacteria actually grow in liquid water that accumulates in the tank. No water, no microbial growth.
