SYNTHETIC NATURAL GAS ENGINE OIL 
SAE (20W) 40

Product Code: ANG

AMSOIL Synthetic Natural Gas Engine Oil is recommended for use in natural gas fueled engines requiring low ash engine oils including:

PRODUCT DESCRIPTION
AMSOIL Synthetic Natural Gas Engine Oil is chemically formulated to deliver unsurpassed protection for natural gas engines. AMSOIL Natural Gas Engine Oil has a low-ash formula with highly effective rust and corrosion inhibitors. It circulates quickly to critical engine components for fast, easy cold-weather engine start-ups and has a very low volatility to remain stable in hot engine conditions. AMSOIL Natural Gas Engine Oil will not break down like petroleum oils because it resists the effects of high temperature oxidation much longer than petroleum oils do.

Inhibits Rust and Corrosion
Natural gas engines are unique in that they must often operate in locations where service is infrequent. Many natural gas engines undergo long periods of inactivity. The rust and corrosion inhibitors in AMSOIL Natural Gas Engine Oil provide protection during periods when the engine is not running or running intermittently.

Improves Spark Plug Reliability
AMSOIL Natural Gas Engine Oil is an extremely low-ash oil, which greatly reduces spark plug fouling and post plugging in two-cycle natural gas engines and virtually eliminates ring belt deposits in four-cycle natural gas engines. In some four-cycle applications, port cleanings have been reduced four-fold.

Maintains Viscosity
Due to its synthetic formulation, AMSOIL Natural Gas Engine Oil is a true SAE 40 oil, yet it passes SAE 20W viscosity specifications for low temperature performance without the use of special additives.

Resists Oxidation and Thermal Breakdown
AMSOIL Natural Gas Engine Oil resists the damaging effects of heat, blowby chemicals and oxidation up to ten times longer than do petroleum oils. AMSOIL Natural Gas Engine Oil neutralizes sludge and acid formation to provide engines with long-lasting performance and reliability.

Performs in Cold Weather
AMSOIL Natural Gas Engine Oil remains fluid in extremely cold temperatures. It resists the low temperature congealing that often occurs in petroleum oils. AMSOIL Natural Gas Engine Oil ensures instant start-ups, fast oil circulation and ideal protection under frigid conditions.

Extended Drain Intervals
AMSOIL Natural Gas Engine Oil affords exceptional extended drain intervals when monitored by an oil analysis program. Periodic oil analysis should be conducted at the engine manufacturer’s recommended drain intervals. Change the oil filter at the recommended engine manufacturer’s drain intervals.

MIXING AMSOIL
AMSOIL Synthetic Natural Gas Engine Oil is compatible with conventional petroleum oils and other synthetic lubricants; however, mixing AMSOIL Natural Gas Engine Oil with a petroleum oil will reduce the drain interval of the AMSOIL Natural Gas Engine Oil. Engine oil additives or after-market products are not recommended for use with AMSOIL Natural Gas Engine Oil.

Note: AMSOIL Synthetic Natural Gas Engine Oil should not be used in automotive engines that have been modified to use propane or natural gas.
