104 fuel and a 1/4 mi. stretch of road?

Martin '01 Formula - MTI Air Box Lid, K&N Filter, Hurst-6, SLP Cold Air Induction & Smooth Intake Bellow Corsa Catback w/Premium Tips '83 V45 Magna

On a serious note: I have a 1999 SS Camaro 6 speed (soon to be a 7 speed) I have many Hi-perf upgrades including a supercharger and true dual exhaust with corvette tips .I drive around 500 miles a year with it. she has only

19,249 miles on it I drove it allot the first year I got it to break it in and test it out.I only take it out to race the local import street racers so they know that American muscle is still the best. I researched this question for months and this is what I have found from many experts of the F-body. they recommended to me to only keep 1-2 gallons of fuel in it, until I was ready to drive then to add only what I plan to burn. they also told me to drop the tank and make sure it was very clean so I would not throw dirt up when I did fuel up. I change the oil every 2 months with a blend I change the fuel filter every 6 months to keep it clean. I start the car for 10 minutes every day and turn the ac on for 10 minutes every week. I will also drive the car around the block to keep the tranny and diff lubed.

I was told that I could add Marvels Mystery Oil to the fuel and oil. I was told that this is a very safe additive and would also help with cold starts.
