non detergent oil was oil made up to the mid to late 50s... all modern oils will have additives that make them "detergent" oil by default. Oil additives to fight acids end up having a by product of cleaning. So you end up with the cleaning effect by the addition of the base additives. The only engines that NEED non detergent oil are engines that have the old "poured babbit" bearings as the newer oils will actually clean the babbit off the bearings. So... if you have a poured babbit bearing engine, you MUST run non detergent oil. In this case you will have to go find a true non detergent oil.
Additves are added to..
fight piston scuffing keep rings free stop cam wear stop cam follower wear dry starting wear after sitting a long time reduce deposits on piston crowns reduce oil vaporized out the breather reduce thickening cold starting and cranking high temp reduced waxing and sludge extreme pressure additives that activate only when an part start to overheat. fiction reducers fight acids due moisture and sulpher creating suphuric acids
and many more..
These were all items identified and fixed by adding additives. So why would you ever run a non detergent raw oil out of the ground?
