Phillips 66® El Mar GEO Oil is a high-quality, non-detergent, ashless gas engine oil designed primarily for use in Ajax 2-stroke cycle natural gas engines. The SAE 15W-40 viscosity grade meets the low-temperature viscosity requirements of Ajax engines where cold starts and frequent start/stop cycles may be encountered.

Features & Benefits
- Ashless formulation helps minimize port deposits
- Protects against sludge and varnish formation
- Excellent resistance to oxidation and nitration
- Protects against scuffing and wear
- Protects against rust and corrosion
- Excellent water-separating properties
- Low carbon-forming tendency
- Compatible with emissions system catalysts
- Does not contain any bright stock, which can cause harmful carbon deposits
Applications
- Ajax 2-stroke cycle natural gas engines (SAE 15W-40)
- Older, horizontal-type 2-stroke cycle natural gas engines, such as those manufactured by Cooper-Bessemer and Worthington (SAE 30/40)
