Gear Oil FAQs

Can you mix synthetic gear oil with regular gear oil?

Yes, you can mix full synthetic gear oil (like AMSOIL SEVERE GEAR and Long Life Gear Oil) with conventional and they are generally compatible with each other. However, mixing synthetic and regular gear lubes can shorten the oil's life expectancy and reduce performance, which is why AMSOIL does not recommend it nor support extended drain intervals where oils have been mixed.

Do you need to add friction modifiers to AMSOIL Severe Gear?

AMSOIL synthetic gear lubes and SEVERE GEAR Oils are limited-slip capable and do not typically require an additional friction-modifier additive. However, for applications that require additional limited-slip friction modifiers, we recommend adding AMSOIL Slip Lock. Slip Lock will help eliminate chatter in mechanically sound differentials.

What is hypoid gear oil?

Hypoid gear oil is specially formulated with extreme pressure additives to be able to work ideally with and protect hypoid gears. AMSOIL SEVERE GEAR Synthetic Gear Lube provides exceptional hypoid gear protection.

A hypoid gear is a type of spiral bevel gear found in many axle differentials and used to transfer power to the axle shafts from the driveline. Hypoid gears engage the pinion under the centerline of the ring gear, which drops the driveshaft away from the vehicle’s underside.
