It can make reading the oil level a real pain.

 Dipper your oil and found this? Your not alone. 
But fear not this is another “quirk” of the rotary engine, most common in the RX-8 however it Han often happen with earlier RX models too. 

In 99% of cases this is simply caused by a build up of moisture in the oil found in the engine. Usually common in the colder winter months it’s nothing to worry about. 

The Solution?

While we recommend regular oil changes for maintenance purposes, in the case of “Mayo on the dipstick” it can certainly help. However on a regular basis look to take your car out for a good drive, once the engine is warm give it a good blast to get the engine and its oil nice and hot (not dangerously hot mind) this should help evaporate some of this moisture out of the oil and make checking your oil level a lot easier.

Remember always check your oil with a hot engine.
