HDAX 5100 Ashless Gas Engine Oil
Gas Engine Oil

They are the recommended lubricant for two-stroke gas engines with high compression ratios and turbochargers, and two-stroke engines known to be sensitive to combustion chamber and port deposits.
Excellent low temperature performance
HDAX 5100 Ashless Gas Engine Oil SAE 15W-40 is less viscous than SAE 30 and 40 oils at low temperatures, so it provides easy startup and improved cold temperature lubrication as compared to straight grades.
Promotes low maintenance cost and long engine life
Minimizes ash deposits
Protects against spark plug fouling from lubricating oil ash deposits. Minimizes ash deposits on valves, piston heads, combustion chamber surfaces, spark plugs, and port surfaces, minimizing the risk of pre-ignition and detonation.
Low ring and cylinder liner wear
Exceptional engine cleanliness
Minimizes engine deposits at both high and low operating temperatures through the use of an ashless dispersant.
Minimum viscosity increase in severe service
Ashless oxidation inhibitor minimizes viscosity increase allowing for long oil drain intervals.
Proven performance
In older four-stroke naturally aspirated and turbocharged engines.
HDAX 5100 Ashless Gas Engine Oils are recommended for gas fueled engines manufactured by:
- Ajax
- Caterpillar (except 3400, 3500, 3600)
- Clark-Dresser
- Cooper Bessemer (two-stroke)
- Dresser-Rand (Ingersoll-Rand) Categories I and II
- Fairbanks-Morse/MEP
- Waukesha VR and Intermediate/Clinton
- Worthington (two-stroke)
SAE 15W-40 oils may not be appropriate for large medium speed gas engines.
