We get alot of questions from customers wanting to know what kind of engine oil to use in their Chinese GY6 150cc engine.  Read On....

Engine Oil  (SAE 10W-40)  and summertime temps (SAE 20w-50) and if this engine is ATV or Go Kart driven in winter temps (SAE 10w-30)

Maintenance and Tune-Up Procedure

Our shop uses Valvoline SAE 10W-40 SYNTHETIC oil or another name brand oil. 

SYNTHETIC OILS ARE GREAT FOR THIS ENGINE BECAUSE OF NO INTERNAL WET CLUTCH

Checking the Oil

• Place Unit on a Flat Surface
• Remove the dipstick and wipe off with a clean cloth
• Put dipstick in hole WITHOUT screwing it in
• Check oil level to see if its between min and max indicators
• Add oil as necessary to reach required level

Changing the Oil

• Run the Unit for at least 5 minutes or until warm then shut off
• Place suitable container for draining oil beneath engine
• Container should be capable of holding at least 1 gallon
• Remove the engine drain plug, oil filter cap, spring, and oil filter screen.
• Drain oil completely
• Check condition of O-ring and filter screen for foreign material before installing
• Install drain plug and torque to 12 ft. / lbs
• Fill with 25 to 31 oz. of API Classification SF-SG (SAE 10W-40) oil
• Doublecheck by adding little over 1/2 quart oil first.
