ValvTect Marine Gasoline Additives

The Best Solution for Performance Ethanol Related Problems

X-Tended Protection+ Gasoline Treatment


Due to potential engine problems caused by ethanol gasoline, boaters are using fuel additives at a record level. Unfortunately, many of these additives are ineffective and their claims unsupported by engine manufacturer and petroleum industry tests.

Verified by engine manufacturer and ASTM tests, the new XP+ Gasoline Treatment is proven to stabilize gasoline, prevent corrosion, control moisture to help prevent phase separation, reduce octane loss and clean-up carbon deposits.

Ethanol gasoline destabilizes quickly and can prevent starting, cause stalling and plug fuel filters. ValvTect XP+ Gasoline Treatment is test proven to stabilize fuel for up to one year. As established under ASTM test procedures, it improved fuel stability 130% better than enzyme fuel treatments. In the ASTM Water Interface test, ValvTect's additive was 50% more effective than enzyme-based additives, thereby better reducing the chance of phase separation. Additionally, ValvTect was substantially more effective at preventing rust and corrosion.

Documented in Chrysler and BMW engine tests, ValvTect XP+ Gasoline Treatment helps prevent and clean-up power-robbing carbon deposits from fuel injectors and intake valves. This results in improved fuel economy, better performance, reduced exhaust emissions and longer engine life.

Specially-formulated for marine engines, ValvTect XP+ Gasoline Treatment is available at most leading marine supply dealers.

4 oz. bottle treats 40 gallons of gasoline.
16 oz. bottle treats 160 gallons of gasoline.
32 oz. bottle treats 320 gallons of gasoline.

ValvTect Marine Motor De-Carb

Today's gasoline is very different than it was a few years ago. The burning quality and the addition of various chemicals have made it prone to leaving significant amounts of carbon deposits in hotter burning marine engines. If these deposits are not removed, they cause reduced engine performance and even powerhead failure, especially in large 2 cycle engines.

Marine Motor De-Carb provides quick, complete clean-up of carbon deposits, gum, and varnish that reduce engine power, performance, fuel economy, and cause powerhead failure.

Just one treatment removes carbon deposits to drastically improve engine power and performance. Spray directly into carburetor or air intake. For all 2 and 4 cycle engines. Use at the beginning of each season or every 50 hours of operation.

ValvTect Marine Motor De-Carb is designed to:

  • Remove carbon, gum and varnish.
  • Prevent powerhead failure.
  • Free sticky rings.
  • Restore power and performance.
  • Reduce fuel consumption.
  • For 2 & 4 cycle engines.

Available in 13 oz. spray can.
