The AMSOIL marine product line is growing again. AMSOIL Marine Engine Oil is now available in one-gallon (3.78-liter) containers for boat engines with larger sumps, covering a wide range of the most popular marine brands and models.
Why it Matters
Engine performance and reliability are keys to spending more time on the water. However, marine engines operate under high loads for extended periods and face constant exposure to wet environments.
The extreme combination of high-rpm engine operation and water invites premature engine wear and corrosion that can reduce engine performance, damage engine components and eventually cause catastrophic engine failure.
On average, a gas-powered marine engine runs at about 5,000 rpm to power a boat at 26 knots (30 mph). In contrast, an automotive engine powering a car 60 mph runs at about 2,000 rpm. The higher temperatures and mechanical stress in marine engines cause inferior oils to break down and lose viscosity faster.
Moisture also causes rust, which acts like sandpaper on engine parts, scouring bearings, the cylinder wall, piston rings and other components, while corrosion eats away at aluminum pistons and other parts.
Protection and Performance
Rust and corrosion protection are not natural features of motor oil. AMSOIL Marine Engine Oil is engineered with potent inhibitors that guard against the damaging effects of rust and corrosion in harsh marine environments to deliver superior protection that maximizes performance and extends your engine life.
- Go Faster Captain – Do you place a premium on performance? AMSOIL Marine Engine Oil keeps your engine internals clean under the stress of continuous high-rpm and high-temperature operation, so you can run wide-open all day long.
- Boat More Mate – Nobody enjoys breakdowns or getting stranded offshore. AMSOIL Marine Engine Oil helps keep your engine running, no matter what mother nature throws at you, so you can travel longer and farther, worry free.
- Stay Salty Sailor – You might enjoy living on the water, but your boat does not. AMSOIL Marine Engine Oil guards against damaging rust and corrosion where the sun doesn’t shine, inside your marine engine.
