Key Features

Factory-Matched Lubrication Formula

Specifically developed for Erayak original gasoline generators, ensuring precise viscosity balance and optimal lubrication performance under factory engine specifications.

Stable Engine Protection

Maintains consistent oil film strength to reduce friction, prevent abnormal wear, and protect internal components from premature damage during continuous operation.

High-Temperature Performance Stability

Formulated to withstand high operating temperatures and heavy-load conditions, maintaining viscosity stability and minimizing oxidation breakdown.

Enhanced Combustion Efficiency

Supports smooth piston movement and valve operation, promoting stable combustion and reliable power output for home backup, construction sites, and commercial applications.

Engine Cleanliness Control

Advanced detergent and dispersant additives help reduce carbon deposits, sludge formation, and internal contamination, maintaining long-term engine reliability.

Direct Replacement for Routine Maintenance

Designed as a factory-recommended engine oil for Erayak generators, simplifying routine servicing for technicians, repair centers, and authorized distributors.

Engine Oil Working Principles

Engine oil circulates throughout the generator engine system and:

Lubricates moving components such as pistons, crankshafts, and camshafts
Reduces metal-to-metal friction and heat buildup
Forms a protective oil film to prevent surface wear
Helps dissipate heat during extended running periods
Suspends contaminants and combustion residues

Maintains stable engine performance during:

Load variations
Cold start and warm-up cycles
Continuous long-hour operation

A properly matched factory-grade engine oil helps extend engine life, reduce maintenance issues, and improve overall generator reliability.
