oil change
Have been running Royal Purple 20/50 XPR since engines rebuilt. Have changed it once not long after breakin. Now was wondering how many hours should I run before changing.
Also I'm hearing that "racing" oil has LESS additives because it is intended to change after each run. Is this true? So what is the advantage of running these? Just paid 300.00 for 2 cases of RP. Ouch.
