Something I forgot to mention earlier regarding Mobil products.
Aside from Mobil 1 providing quality oil and filters, I also support them because they supported the ZR-1 during the early years of its development. They also helped Tommy Morrison break the world record by donating money and product in his effort. They were also instrumental in figuring out how to keep the wheel bearings cool enough to sustain the 24 hours of 180 mph that was needed to break the record.
