As title says, my truck has sat for about a year. Before I parked it in May 2012, I changed the oil with the normal Mopar filter and synthetic oil. I jumped it off in September 2012 and let it run for about 20 minutes. I've got a guy interested in buying it, and I'd like to make sure it's running before I show it to him obviously. Do you guys think the gas will still be good? I'm thinking the oil will be good enough to run it, but I'll change it before he comes to look at it. Anything else I need to do? Thanks guys.

 

Parked indoors or out? I would try to start it, see what happens. May need to drain the old gas out. Change oil and filter.

 

How much gas is in the tank? Check the battery for good charge, check all the fluids, check hoses for dry rot/cracks, check you tires, maybe grease the ball joints. If it starts up and idles fine then I wouldn't worrie about the gas to much but it would be good to get some fresh gas in there before the guy checks it out.

For future reference if you know a vehical is going to be sitting, it's good to throw some stabil in the tank to preven the gas from breaking down over time.

 

It's been parked outdoors. I didn't think it would sit this long. I believe there's about half a tank of gas in it now. Thanks for the tips.

 

Might throw a bottle (yes a bottle) of Startron in it for good measure.

 

Use Stabil Marine Formula, it's much better than regular Stabil.

 

charge battery.
smell the gas. if soured and stinky, drain it. otherwise add a bottle of any treatment that will absorb water.
check the oil, radiator, brake pedal pressure.
bump the starter gently a couple of times to make sure its not froze up.
cross your fingers and fire it up.
