PRODUCT DESCRIPTION
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.
