Hi All,
From the day we accepted delivery of our 90 ZR1 the engine always started with the 2 second rattle from the chains, guides, case or whatever. I have tried numerous recommended brands of filters with no improvement until I purchased the NAPA Gold 1324 and did an oil change just the other day. The rattle at start up and even starting when warm is gone. Just thought I would share that info.
The oil, as always, is Mobile 1 10/30.
Best regards.
Don in VT.
