AMSOIL SAE (20W)-40 Synthetic Natural Gas Engine Oil (ANG)

SAE (20W)-40 Synthetic Natural Gas Engine Oil (ANG)

Formulated to Provide Top Efficiency in Engines Fueled by Natural Gas

Low Ash, API CC

AMSOIL Synthetic Natural Gas Engine Oil (ANG) was developed to deliver unsurpassed performance in natural gas engines calling for an SAE 40, low-ash (<.50%) lubricant.

Performance Without Compromise

AMSOIL Synthetic Natural Gas Engine Oil's low-ash formulation minimizes combustion chamber deposit formation, critical in continuous operation applications. AMSOIL ANG also significantly reduces valve recession, a common problem with other low-ash oils. AMSOIL Synthetic Natural Gas Engine Oil is thermally stable, allowing it to combat oxidation, oil degradation and internal deposit formation.

Maintains Viscosity

AMSOIL Natural Gas Engine Oil is a true straight-grade SAE 40 oil, offering maximum protection against viscosity loss while minimizing internal oil consumption. Field studies have reported up to a 50 percent reduction in internal oil consumption when compared to competitive oils. Due to its synthetic formulation, AMSOIL Natural Gas Engine Oil does not thicken as readily and qualifies as a multi-grade SAE 20W-40 oil without the disadvantages that come with the use of viscosity improvers. This allows the oil to be used over a broader ambient temperature range and in many cases eliminates the need for a conventional multi-grade product.

Extended Drain Intervals

AMSOIL Natural Gas Engine Oil may be used for 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.
