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.
