Engine oil

So back to non detergent oil. I’ve been running Harley detergent oil for lack of a lot of availability of anything else but was under the impression that without a filter using non detergent oil the sludge accumulates in the oil tank and flushing the oil tank (and sump if equipped with a drain) with every oil change keeps things in check and the sludge doesn’t recirculate as much.

Regardless of the theory; why would you want to do a bunch of extra maintenance in order to run an oil which has been obsolete for 70 years and isn't what the manufacturer itself sold for your vehicle when new?

You're literally asking about going backwards a decade in lubrication technology for your bike from what it enjoyed when new . . .73 years ago!

You got it backwards, Chuck,..

The non-detergent is used in a veteran to avoid extra maintenance.

Why risk a detergent and break sludge loose?

DEEBS arbitrarily wants to dissect everything, even if its a barn-find that deserves a good last hurrah.
