I saw a thread that pointed out that the Moroso pan holds more oil than the stock pan. This morning I poured all the factory motor oil back into the motor (I had saved it all in a brand new homer bucket). A few minutes later I pulled the dipstick and it shows a level that is at the top hole. Should I add more oil? What reference on the dipstick do most people use to know the level is correct or do they just eyeball that it should be a certain amount above the top hole?
