Yikes, the oil on the dipstick seemed a bit high when I went to recover the truck. I thought it was maybe a gallon over the 5 gallon capacity. Boy was I ever wrong. I decided I would drain off a little of the crankcase oil because the color indicated it was just changed not so long ago. I decided to drain the rearmost compartment of the oil pain. Thinking only a gallon would come out...it kept coming....5 gallons to be exact. In disbelief I decided to just drain the entire crankcase. Well, 10 gallons later she was drained. Not sure who did the previous oil change but someone was asleep at their post. Oil pressure read a steady 40 all the way home and at idle. Hmmmm, anything else I need to look at? Do you guys think any damage could have occurred? I only drove it 60 miles but who knows how many miles were driven with too much oil. Please advise
