I've heard of this stuff shell makes V-Power or sumthin that cleans your engine while your driving. And is okay to mix it with the gas I had in my truck Unleaded Low Octane (the lowest)???

 

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.

 

so in my 93 it would be ok?

 

It won't hurt it at all and it probably won't help it much. Premium fuel is just fuel that burns at a slower rate, so it is less likely to cause detonation (pinging). It is useful in engines that run high compression ratios and/or lots of spark advance. Your engine was designed for 87 octane fuel.

 

o ok ill keep it w/ 87 then

 

I have always thought of premimun as a waste unless you need it. It was burn slower and therefore might not burn completely and therefore give you worse gas mileage as some will be wasted when it is not burned.

 

Sure helps when ya hit the juice though

 

i put the highest grade fuel in my truck and i get great gas mileage with it.. there is a store here in fl that sells racing fuel.. but thinking bout puttin that in the truck.. but its like 4.75$ a gallon

 

I need the premium stuff, because of the bama programer.

 

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.

 

haha but my plugs arent bad anymore... hell if i put the racing fuel in.. i might blow my whole engine... whoops.. good reason to upgrade to a 4.0 :).. but i dont put the 93 in my truck all the time.. like every other 2 weeks or so

 

Or unless your truck pings on 87. Mine generally does, so I run 89 to keep it quiet.

 

o2 sensors love that leaded fuel.

 

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

 

read this^^^

he explained it much better than me. i suggest fixxing the ping. prolly cost less in the long run

 

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?

 

And I'm sure you keep a fuel log and have proven this.. meaning isn't just a percieved improvement.. right?
I'd agree.. although it isn't always about saving money. Some would gladly spend more money just for the opportunity to use less fuel. Using less fuel generally means expelling fewer emissions and in many people's minds, equates to a lower impact on the environment. This is why you see so many early adopters of hybrid tech and the sort. The initial purchase may outweigh the savings they'll see in fuel bills over the live of the vehicle, but that isn't necessarily the point.

 

no i dont have a fuel log.. but i can make on to show u if u want me to

 

Why pay more money...

it not going to make your truck go faster...

 

what could be making the ping?mine does it too but the ford people said it could be carbon buildup?

 

Carbon buildup could definately do it.

Some trucks do it from the time they leave the factory.

 

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

 

ah, just leave the cats gutted....haha

question....is there anyway to clean out the carbon stuff, w/o taking the engine apart....and what exactly are u meaning, timing chain? the serpentine belt?

 

Used to use a product called RxP, sold at any autozone or other auto parts store. Supposed to do just that, remove carbon buildup.

 

sweet!

i'll have to pick some of that stuff up!
