I searched but cannot find any posts that say what the oil capacity of the 22RE is. I ask because AutoZone
says it's 4 4/5 quarts, but after dumping in 4 quarts, my dipstick says it's full. Now I realize that not all of the old oil is going to run out, but I've never experienced almost a whole quart staying in the pan, and I've changed oil on quite a few different cars.
What complicates the situation is that I know that this truck had an engine swap before I bought it, and it could
have the wrong dipstick installed.
