Fuel Additives
Gasoline and diesel injector cleaners, cetane boost, stabiliser and anti-gel.
What this is for
Two honest jobs here. One is cleaning: direct-injection engines build deposits on intake valves that fuel never touches, and injector tips foul. The other is winter and storage: anti-gel keeps diesel flowing in the cold, and stabiliser keeps ethanol gasoline from separating in equipment that sits.
Check this before you order
Match the additive to the fuel and the problem you actually have. Dose rates are on the label and more is not better.

No prices on this page — here is why
AMSOIL sets pricing and takes the order. As an Independent AMSOIL Dealer I do not publish their prices, so the number you see on the AMSOIL page is always the current one. If you buy more than once a year, look at Preferred Customer first — it changes what you pay on every order.
