For the first 5-6 years I had my last pickup I treated it like I had others for years, when low on gas, fill it up. Then one trip I hooked to the camper with 3/4 tank of gas that had been in the tank for about 3 months. Truck ran, but spent a lot of time in lower gears. Stopped when 1/2, filled, ran better. Filled again at half, more improvement. Now, unless I'm going out of town, when it gets to 1/4, I put in 5 gallons. If we don't go camping that will last a month. That way, when ready to hook up I can take on at least 15 gallons of fresh gas, and she does better.
True story ^. Although I'd liken it to old gas not bad gas. Although it does happen, the only bad gas I've gotten in many years is from gettin real durnk the night before or sometimes Mexican food! lol
Quality of fuel, age of fuel and ethanol content for stored fuel is real.
One of the old wives tales about filling the fuel tank on stuff before storage to prevent condensation build up is , well a wives tale unless we're talking an old John Deere parked in the snow all winter with a crappy metal tank and a crappy metal gas cap.
I'll take an empty or mostly empty tank during storage in everything I own with an engine along with the condensation "risk" over a full tank of 6-12 month old gas. Period unless gas is non ethanol stabilized, race fuel or avgas.
And if one is worried about condensation, fill with a tank of 10% ethanol and let er rip. It's like adding 3 cans of HEET to the tank.
