A tale of two Brians

Words of wisdom from Dad: In cold weather you should keep your gas tank as full as possible (for example fill up when it's half empty instead of waiting until it's near empty). The reason is that in cold weather, water vapor condenses on the inside of the gas tank not covered with gas, especially if the temperature varies from warm to cold, etc. Water is heavier than gas so once it condenses it goes to the bottom of the tank and is sucked into the engine. You may not even notice, but you may notice sputtering or even stalling and hard starting. The more full you keep your tank, the less surface area the vapor has to condense on. There ya go......isn't your life enriched now?
