This is the first time I have ever owned a truck with dual tanks. Since it will not be driven a great deal I am worried about the gas going bad on me. What do you guys do to keep it from turning bad?
I had a coworker that bought a used two tank F150. The old owner always ran off the front tank and never switched tanks. The first time my coworker switched tanks he created a huge dirty fuel line problem due to very old gas. I prefer to burn one tank dry then run the next one dry and alternate back and forth. Sta-bil is supposed to keep gas fresh for two years. I will find out. I have it in five different vehicles and several small engines. As I am serving my 19th year for good ol USA in Korea. Walmart has Sta-bil in a fair size bottle. Treats at least 80 gallons for about $10.
I have some antique cars that had gas in them that was over a year old and they ran ok. I would try to use the gas within a year & put new in. Also fuel gauage floats in the gas tanks that sit for long times tend to stick in position causing gas gauges to stay in one place. Good luck to the guy in Korea as I was over there years ago during the Pubelo crisis.
Thanks to everyone who responed. I plan on driving the truck maybe every other week for a day to keep seals fresh and juices flowing. I will probably do as Shotgun suggested and not fill up the tanks but put maybe $10 worth in each tank and then alternate.
Aslo, while I was at the pump getting ready to fuel up I had a friend pull up in his 97 and told me I shold only burn premium. I followed his advice, but is it really necessary? I don't see any warnings like I do on my SHO.
Shotgun, good luck in Korea. Can you guys sneak some special forces up north to reprogram their missile guidence systems so they act like a boomerang when launched? Be careful. My prayers are with you.
The rule of thumb for which octane to use is buy the lowest octane that does not ping a lot in your car. Several car magazines recommend this. Some even say some very light gentle ping under load is a good sign that you are at optimum octane and are obtaining the best mileage.
My 94 F250 460 runs dandy on 87 unless I am towing in hot weather or in hills.
Unless your truck is modified with extensive engine mods, you probably don't need 92 or even 89.
