Posted: Wed Oct 15, 2008 3:52 am Post subject: Fuel in the Oil

I just got my oil analysis back and I was told that I have 2.3 % fuel in the 

oil and the value should be less than 1%.



I have an IO 360 A1A, and I mostly use unleaded auto fuel.  Blackstone labs 

thinks I should check the injectors on the engine and any other source of 

fuel.



Any ideas on what to check for, and what might be causing the problem?



Thanks

If you are running a mechanical fuel pump there might be a slight leak internally past the diaphram. I have seen that happen before several times, if not it has to be in the injector area somewhere. To have that much fuel get past the rings and into the oil would be a long shot for sure. Keep us posted and how this turns out.

I'm having to look harder and harder to find un-ethanol-ed unleaded auto gas around here, Bob.  Just dumped 15 gallons out of the plane that the wife bought for me at the deep discount Kroger station, because I saw signs on the pump later that week that said may contain 10% ethanol.  Did the water test, and sure enough- positive for corn squeezin's.  Not until after I dumped the first jerry can from the wing tanks into my pickup truck tank did I think about the residual 100 LL that was mixed in there from a September cross-country.  I hope I have not ruined my cat converter; I have another dozen gallons of premium gasohol / 100 LL mix that I can only burn in the motorcycles and lawnmowers ;-(

 

Be careful about the ethanol - it's making inroads in our region, and it's time for the high vapor pressure winter mix to hit the market, too.

Bill,

 While the lead will coat the catalytic converter and the oxygen sensors, it's affect will be only temporary. Once you put pure unleaded back into the car, the lead will burn off of the cat and the oxygen sensor.

 around here, Bob.  Just dumped 15 gallons out of the plane

 that the wife

 bought for me at the deep discount Kroger station, because

 I saw signs on

  Did the water

 test, and sure enough- positive for corn squeezin's. 

 Not until after I

 dumped the first jerry can from the wing tanks into my

 pickup truck tank did

 I think about the residual 100 LL that was mixed in there

 from a September

 cross-country.  I hope I have not ruined my cat converter;

 I have another

 only burn in the

 motorcycles and lawnmowers ;-(

 

 Be careful about the ethanol - it's making inroads in

 our region, and it's

 time for the high vapor pressure winter mix to hit the

 market, too.
