I was driving from work when a message came up to check oil pressure. I did and found about a quart of gasoline mixed with the oil. I have not flooded the engine at anytime and the truck starts very good.
Ichanged oil and filter and the same result (gas in the base).I changed plugs and wires last summer.While the engine seems to be running fine, on occassion she will miss for a few seconds when it is cold.Iam concerned and am 45 miles from the nearest garage and i do not want to ruin my engine trying to get there. Any help would be greatly appreciated.
