Re: Important Information About Mobile 1 Synthetic Motor Oil For Mach 1's

I ran 5w-30 for the summer last year and have since switched back to 5w-20. I feel like I've done the right thing. Really though, I was only worried about the track visits and going up to redline in the heat of the summer. I've always used full synthetic, so I feel okay about switching back.
