Hi folks-
	Just before my trip to Indy, LA and elsewhere, I changed all my Miata
fluids to Red Line stuffs. In the motor I had used dino oils for 53K and used
the Amsoil flush to clean the engine before installing Red LIne 10W40. During
the trip I noticed that my lifter clatter had increased seemingly exponentially
since changing to Redline. My question for other synthetic users is: Did you
install 10W40 or 5W30. If 5W30 and you had previous lifter chatter, did the
noise go away. I've gone 10K miles on the trip so it's time for the oil change
and 60K service so should I switch to 5W30? Any thoughts are appreciated.
