I drive a 94 Miata and they have a propensity for valvetrain noise upon start-up and really valvetrain noise in general. I was running Rotella T6 5W-40 and a Fram ultra and there was a rattle almost every start-up.
I have switched to a cheap (red can) Purolator and Mobil 1 high mileage 10W-30 full synthetic. Since the change there has been no rattle and there is actually greater oil pressure.
Any thoughts?
