I have a friend who drives a Civic and someone poured 2 gallons of motor oil in his car while he was in the store. I told him to get on my account on 7thgencivic.com and see if someone can help and one guy suggested that we add some gas to thin out the motor oil and run. We did that and at first it ran fine and we decided to leave it running. Well now the check engine light comes on and it idles "REALLY REALLY" rough, it shakes pretty bad. Any of you have suggestion what to do? We tried to siphon the motor oil out but no luck.

 

They put oil where in the gas tank?

 

Moving to Car Talk, not a S2k question. You need to know where they put the oil.

 

They poured the oil in his gas tank.

 

whoever suggested running the car with oil in the tank is a flat-out idiot and should not have given advice. The tank should have been drained. I hate to generalize, but your average civic "enthusiast" knows next to nothing about any mechanical or performance issues and this only proves it. If siphoning was the next course of advice (which can really f*ck up your health), these idiots should be put in their place.

2 gallons is a lot to thin out, especially with a 13 gallon tank. I would imagine the fuel filter is clogged at the very least, and the injectors are likely heavily damaged, too. I would imagine that is (hopefully) the extent of the damage.

also, how did you find out someone poured oil into the gas tank? did your friend see it happen? was it rednecks bashing your honda or something.

 

How did he know it was 2 gallons too?

Also, I'm pretty sure they sell dedicated siphoning tools that don't require you to suck gas fumes into your lungs .

 

do you HONESTLY think that he used those tools or his lungs?

 

No my friend did not see it happen, but when he came out of the store he saw his gas cap open, an empty 2 gallon motor oil jug, and oil on the side of the car. What do you suggest doing in a situation like this?

 

Somebody really hates your friend. Doesn't sound like a quick fix. Looks like you have to bring it to a shop.

 

I would go back to that civic site and chastise them for giving you that advice.
