Hi Scotty, is it okay to drain and change 5W-30 full synthetic oil/filter every 5000 miles for a oil burning 98 Corolla 171,000 miles? I top it off with oil as needed every two weeks as it burns oil. Love this quote from your video “engine is very expensive but oil is cheap”.
Id just top it off
Adding Marvel Mystery Oil to my crankcase has seemed to help a little oil burning in my 1998 Toyota RAV4. In the gas tank is helping >> my mpg, too.
