hello
i have a 92 lt1 w 90,000 miles i am going to be storing away for the winter in my garage soon this will be the first time i have put it away for a winter sinced i have owned it since i bought it back in the summer of this year and wondered whether or not i should put fuel stabil in the fuel tank (the same stuff i use in my lawnmower) for fear of it ruining oxygen sensors when i do drive it again in 7 months or so. i am going to fill the fuel tank, change the eng oil and filter and disconnect the battery is their anything else i should do?
I have an 89 L98 and live in a Detroit suburb and do the same things you talk about, including adding the Sta-Bil, and have never had a problem. Don't worry about the tires flat-spotting (but make sure they are inflated properly), that will take longer than the 7 months it will be stored. If you can, drive it in the Winter, DO NOT just start it and let it run without taking it for a drive. The oil must get over 212 degrees to boil off the water and get rid if the condensation, otherwise you are just making the situation worse. I was told nothing can replace actually driving the car for 20 miles, I just wait for dry, sunny days to do it.
I'll chime in with the michigan boys! I don't do any of that - I leave the battery hooked to the charger, no fuel additive. I do start it and let it idle until the therm. opens every 2 weeks or so. Going on 4 years now with no problems. I even take her for a spin prior to the most major salt deluge! I do put a board down under the tires so the pressure loss is minimal. :seeya :cheers:
Don't bother changing oil and filter, it's just money sitting around in the oil pan. Save that for when you take her out of retirement.
Fuel stabilizer is a good idea and a trickle charger on your battery in the car or out of the car. Batteries hate cold so if it's nasty cold where you live bring it into the garage and put it on a piece of wood with a trickle charger.
