Just trying to find better ways to save gas. I dont drive it alot now and I dont drive over the speed limit. A full tank lasts about 10 days If 3 or more days it just sits at home. I dont drive it over 20miles a day. I see alot of additives at Autozone but dont no which one to use or if I should use one at all.
The only additive to use is occasionally add a can of fuel injector cleaner. In your case once every 6 months will be fine. READ the can.It must be safe for catalytic converters. Brand doesn't matter (cheaper-the-better)
Fuel additives are a marketing scam. Do not put anything into your gas tank unless it is gas (with the octane rating recommended by Ford). It's a gamble and it's expensive.
The additive will clean your fuel system, however it will also build up on your plugs electrodes. So after running the solution you will need to remove your plugs, clean and re gap them. You will notice a power decrease and most often a hesitation after running these cleaners. I run the cleaner GUNK ALL IN 1 every year , it works wonders for the fuel system parts but it cakes up on the plug tips reducing ignition. I drive a 17 year old F150 with a 302, 5.0 liter engine and it has over 750,000 miles on it with out any work done to the heads or block. Expect hesitation problems after running this tank , it will be the plugs caked up. After you clean the plugs it will run perfect from then on.
