I have a V6 Double Cab 4x Offroad 05 Taco with about 70,000 miles.
The check engine light came on last week. At thet time it started to knock. I took it immedietely to my mechanic. They checked the oil pressure among other things. It was down to 7lbs. The oil light light had not gone on. They drained the oil and their was gas in the oil. They changed the oil and it runs fine now. They cannot explain what happened. Anybody heard of this?
