im doing the swap to single this month, i will post if i notice any change in gas consistency in my oil... if both me and wonder experience the same thing i will conclude that it was somthing in the stock twin system

Not sure how you could blame the stock twins on the gas in the oil. Did you get the injectors cleaned or replaced to larger size when you went single? I'm pretty sure the gas in the oil is from leaking injectors.

The smell of gas in the oil is NORMAL, period. All rotary engines have blow by no matter how tight the tolerances are. It is the inherint design of the rotary engine. I have build hundreds of engines from turbocharged, N0s, supercharged, bridgeported you name it they all do it.
Change your oil often! In forced inducted engines change the oil every 1500 miles maximum, period no exceptions. On normally aspirated motors 2500. If you race the car change the oil before and after the event.

Mr_rx7_tt,

Right on! I was just going through the posts, hoping to see the right one...and there it was.

Guys listen up...it's normal. The rotary engine is going to get gas in the oil, and it's going to burn oil too. Everyone should know that by now.

I have also experienced the gas smell in my oil and I've noticed that it appears runny after the car has sat overnight after running it hard. I have a street port and was told by a reputable rotary shop that this is normal. I change my oil every 1000 miles with red line because if gas is present it will break down the oil quicker.
