I have been developing a mild hearing loss and find the wind buffeting my ears has become a big nuisance. I just started wearing a Bell Pit Boss half helmet with cushioned ear pads, and this has eliminated the wind buffeting of my ears. I can hear my exhaust note much better and my driving experience has significantly improved. I’ve also read that eliminating wind buffeting allows you to hear horns and sirens better as well. That makes sense to me.
I’ve been reading through the Mazda Miata forums to see what kind of transmission oil they have been using. Many of them have highly recommended Motorcraft XT-M5-QS transmission oil. This is a fully synthetic SAE 75W90 GL4 transmission oil which my manual recommends. They have raved about how silky smooth shifting is with this oil even in lower temperatures. My transmission oil was due for service, so I put this in today and I notice a difference. Agree. Silky smooth shifting. Shifting before was not a problem, but I agree there is a difference in how smooth shifting is with this oil.
My bevel box has been howling at certain speeds. I called Morgan Motors of New England and they recommended Redline 80W250 GL-5 gear oil. Wow! I can still hear a soft whine of my drivetrain, but no bevel box howling. Thank you, thank you, thank you!
