During the '60s both Oilzum and Valvoline racing oils were detergent.  I expect 
that Valvoline racing oil still is.  My experience is that changing oil every 
3000 mi. or after each race, whichever comes first, will keep the engine (in 
this case a turbo corvair) free of crud, with negligible varnish.
