Milky Oil Air Cooled Engine – FAQ

When gasoline is consumed or ignited, water vapor is one of the combustion components.  

Inside a cold engine, this water vapor can condense and collect in the engine oil. You can see the separate components since oil and water don’t mix. Forming a milky appearance in the oil.

FYI, Engine oil can have an anti-emotive oil additive, preventing the water droplets from becoming too big and replacing the engine oil as it flows. This allows oil to keep doing its job without losing viscosity.  

How Do I Fix Milky Oil Air Cooled Engine?

As the motorcycle engine warms up, the trapped water in the engine oil will heat up and convert to vapor.

Hi I’m Tom, A New Motorcycle Rider and Blog Author.

I am a new rider(Pa Learners Permit at the end of 2020, and I received a Pa Motorcycle License in 2021 after passing a Motorcycle Safety Course).

I bought my first motorcycle, a TaoTao TBR7, at the beginning of 2021 and have been doing upgrades on that motorcycle since.

I added to my motorcycle collection by buying a Boom Vader Gen 2 in 2022, and that Grom-Clone motorcycle has been upgraded by me as well.

I continue to ride my Boom Vader Gen 2 motorcycle as well as my TaoTao TBR7 dual-sport bike.

Fun Fact: I’ve only been on one group ride.
