Should I change my oil? #4719296

Last weekend I went to a buddy's house to put long tube headers and motor mounts in my Camaro. On the way home the car was running kinda rough, so I looked under the hood, and I discovered a coilpack was unplugged during the entire 30 mile drive home.

Should I be concerned about fuel dilution from fuel sneaking past the piston rings on that cylinder?

I used Redline 5w30 before I put it in storage, and have only put about 75 miles on the oil. I'd rather not dump it if I don't have to!

No because the fuel just was blown out when the exhaust valve opened. Ed

Nope. That short a drive won't have made a dime's worth of difference.

With 30 miles of fuel wash, I would at least do a compression test on the effected cylinders.

I'd be more worried if I had killed a catalytic converter or not.

Thanks guys, I guess I won't worry about it then.

No need to worry. I'm 100% certain that no catalytic converters were harmed by this.
