Oil Smells Of Fuel

bigdinz · #1 05-29-2005, 01:36 PM

I changed my oil today and did a flush as well. When I drained the oil the first time I swore it smelled like it had gas in it. What would be the cause of this? All "tune-up" parts have been changed.

Any ideas?

The oil without the flush smelled like gas?

What are all the tuneup parts your replaced.

Yes the first(bad) oil smelled of gas.

I replaced plugs,wires,cap&rotor,pcv & fuel filter.

did this gas smell come from the oil with the flush in it?

Please relax on the defensive replies, it was only a question.

If your oil has a strong gas smell, this in part is normal, it a certain extent.

I would replce the PCV valve seeing it is there to remove those post combustion gases for reburning instead of them being impregnated into the oil.

It was a joke. Did you notice the (Laugh Out Loud)lol at the end? It WAS a silly question to ask in the first place. Just letting you know that I know more than you thought I knew.

Thanks again for all your help!!!!

Does your truck run rough? When you drained your oil, was the oil that first came out thinner than the last of the oil that came out. My jeep had the same problem, a bad fuel injector. The fuel injector was dumping so much fuel that that the fuel was going through the rings of the piston into the oil pan. But that was on my jeep, I don't know if it can happen on an s10. My jeep had rough idle though.

ok ok most used oil smells like gas because of blow by from the use of the engine

PCV valve should fix this up.
