peter78 said:I know some oil companies think their oil can last forever; i.e. 25,000 miles. They recommend you change your oil filter half way through the cycle. From what I have read you lose very little oil. Also, the filter on the V8 is upside down, so when you open it I would imagine you would lose just what is in the filter and I would guess most of it is drained when the engine is off. See third picture in this thread.
oops, the picture made it look upside down. If it isn't then I think a little more will leak out, so you work fast or drain it first. I would put a dirty oil catch drain pan under the filter.Toyota4Me said:And the V8 filter is NOT upside down.
