Hello:
I'm looking for some reasonably priced oils to run in the flat-tappet, relatively high-revving motorcycle engines we have to care for at our dealership.
Will the new CJ-4 synths and 15-40 dyno oils do the job that the old SG-rated oils do (did)?
What's the consensus.
One caveat: FOr one series of these engines the manufacturer INSISTS most definitely in all capital letters) that the oil be SG rated.
