| Dealerships, many independent service shops, tech advisors and many owners, including this one, use the dipstick removal system. It is very thorough for getting all the oil. The MityVac system is a common one used.
I was a sceptic and a "pull the plug" advocate until after I had enough experience using the vacuum removal system. I am now almost exclusively a fan of this method. I have only used the drain plug method on equipment that I cannot use the vacuum.
