Is Premium safe for our Rangers?

Virtually all gasoline has detergent additives. Generally speaking, premium fuel is a waste of money unless your engine needs it to prevent detonation. Late model Ranger engine calibrations have a spark adding algorithm that will advance the timing in the absence of detonation. This can sometimes give a small fuel economy benefit with premium fuel. There is no problem mixing regular unleaded and premium unleaded.

and you wonder why your spark plugs were so bad
if you engine recommends 87 run 87.
unless you have a programmer that requires you run the higher octane then run it.

running premium (unless you have modified the fuel program with a chip or tuner) is a waste of money and possibly bad for your emissions system
unburned fuel taxes your catalytic convertors and can create excess exhaust heat
if your engine is pinging on the recommended octane (87 for modern Rangers) there is something wrong and using premium fuel is a quick and incorrect fix

Those who are actually considering buying premium fuel for the gas milage (perceived or not), you should also be aware of another calculation. Cost per mile.
I.E. If it costs you 35 bucks to fill up, and you get 250 miles per tank, then you pay .14 cents per mile driven. It's a little harder to track, you have to know what you paid for the gas when it is gone.
So even if you do claim to see an increase in fuel efficiency, are you still saving money?

if your motor pings on 87 you have carbon build up or your timing is incorrect could be bad timing chain or related gears. all ford truck motors ( gas only ) are designed to run 87. higher will burn out cats, all of you running 3.0L w/o egr you have 5 cats in your system how much do you think that would cost to replace. about $1500.00
