I could use a little advice as to this situation=I have some mostly GM 60's to 80's vintage cars that generally each get driven around 1000 miles/year. I usually tend to run them towards the low end on fuel and park them inside/unheated for the winter-sometimes a bit longer-then a full load of fresh gas when out of storage. (If a car has been parked with a bit 'too much' fuel in the tank during storage, I've often siphoned all I could get out and then just added that to daily drivers. I used to fill them, add stabil, ect, but haven't done that a long time ago.) Anyway, I've done this 'minimal' proceedure for 15-20 years (10% ethanol for much of it)and haven't had any problems as to 'stale' fuel issues. Lately, 'stuff' got in the way of my normal and I think I need to approach this differently. Some of the cars haven't been started/driven for a year and a half and it will be longer as they will sit for at least another 4 months. As said, I haven't experienced any of the 'carb varnished/gunked' problems, but now may be different. I'm thinking of siphoning out all I can get and adding some fresh along with Stabil-maybe some Techron,ect before cranking them up? Any thoughts?thanks
