Dad's 2005 Silverado has not been run since last summer-- any recomended precautions?
 

Everything should be fine with the fuel,if the truck sets in the really cold climate in the winter yearly i would recommend fuel stabilizer.you can top off the tank and ad injecter cleaner to the tank just incase the gas broke down a little.that will keep the injectors from biulding up any gum.you also may need a jump box for the battery.and lastly i dont drive my truck to much in the winter unless the roads are nice so during the winter months i can go 1000miles in 8 to 9 months without oil change,but i do one anyway when it warms up.you might think of an oil change to,inside the moter can condense like a soda can does in the summer where you can get water mixed with your oil.

Thanks 20"strong
 

Thanks for your reply! I'm passing your reply on to Dad.:) Billie

I would dump some gas stabilizer in there as stated or even a few gallons of high octane-101 100.. You should be fine however.. :) Then run a fuel system cleaner through it.. Good to go

I've been reading forums on fuel stabilizers and I see a lot of discussions regarding Sea Foam, Amsoil, Techron, Stabil to name what seems like the most popular. Is there a stabilizer and cleaner you could recomend?

i used stabil when i had a boat and never had any problems,and i think stp makes one also.

Thanks 20" Strong and Mangled03gmc for your help. Billie :)
