And I still have pinging! I have a 1996 Ford Explorer V8 5.0L with 107,000 miles. I bought FP60 almost a year ago and I just finished the gallon of FP60 and my truck still pings on WOT and when going up hills. After hearing all the positive comments from some people after just a few tanks of gas, i figured I would see some improvment after a gallon/year of use, but there really hasn't been any improvement. Pinging is still the same and mpg is about the same. Truck seems to run just a strong as it did a year ago. All other maintenace on the truck is up to date. MAF has been cleaned in the past and the plugs are not that old. How do i know if FP60 is doing anything? Should i continue to use FP60 and will it eventually clean the chambers enough to get rid of or lesson the pinging? Just trying so see if FP60 is benefiting me and justfy the purchase of more FP60. thanks for all the help.
After 1 Gallon of FP60!

How is the car's mechanical condition. Vac leaks, PCV problems, etc. If there is no external reason contributing to the degradation of the performance and longevity, then it should be cleaning it up. Maybe it was clean to begin with, and there is something else.
With that said, I am in the same boat, I haven't seen any MPG benefit, and I will know soon if the plugs got cleaner from using it.

are you sure it isnt a rattling pcv valve? Some chevy trucks get that, and it is often mistaken for other things.
I have not ever found any statistically significant MPG enhancement from using FP. What I have noted is quieter auxiliaries such as the fuel pump. Lubricity is my main concern, and IMO FP does that nicely.
Nothing that you put in the fuel at such low doses is going to have a miracle effect, even if a gallon of it is consumed in time.

do a combustion chamber decarbonization treatment with POW, plain old water, some use distilled or fancy deionized, but why, engines suck in lots of dirty moisture in dirty air every year.
1 quart thru the TB plate hole with a small tube using vacuum to draw out will micro burst steam clean the top of heads and rest of combustion chamber....into hot engine at 2k rpm, nice steady stream just to point of knocking down rpm, should gets lots of steam out the exhaust....take out on freeway at 50 mph+ for 10 miles...hot carbon deposits are the main cause of predetonation....
put scanner on the engine and check base idle timing and total high rpm advance for specs...your '96 is OBDII so more advanced info avail...use the scanner to look at knock sensor while on hard pull and at fuel trim levels...may also be tired slow old O2 sensor running the engine too lean...also look at engine temp with scanner, may be running slightly hot which will cause predet.....scanner will tell you far more than ears
some use Seafoam into TB/plenum but water is free...a Seafoam injection/soak will clean the ring packs of carbon buildup and help compression
do you hear the "pinging" while crusin on the flat?

Thank for the replys. There are no other mecanical problems with the vehicle that i can see. I was thinking of using a cleaner through vacuum, but didn't want to run the risk of hydrolock, so I figured FP60 would be the safer way to clean everything up. After a years use I though it would of atleast help the pinging which meant it cleaned the chamber up, but it is no different. No, there is no pinging while cruising on the flat, the only time I get pinging is either at WOT or accelerating up a hill.
steelhead, I don't believe my 96 has knock sensors. In order to use a tube through the tb plate i would need to take the intake tube off and disconnect the MAF. Is it ok to run the engine with these disconnected? Also how do I check for vacuum leaks? Also I don't have a scanner (would like to purchase one soon) to check for those tests. I do have a bad O2 sensor (bank2 sensor1) that set the check engine light off about a month ago that i will be replacing, but the pinging has been around for as long as i can remember, so i am not sure if that is causing it. thanks for the help

have your egr checked out.
what octain fuel are you using? could try to run 91 octain and might cure pinging. also with your spark plugs. could try a colder range plug. I know alot of dodge truck owners with the 5.2 and the 5.9 V-8 has gone one plug cooler and cured their pinging. also they talk about the belly pan gasket blown in those 2 motors can cause pinging. I know nothing about the 5.0 engines so dont know if they have a belly pan gasket prob.. I would try a cooler plug and it might help.
I would also try one range colder plug and see if that helps. You should not have to run 89 or 93 octane in a Ford 5.0!
I use a gallon in my LS1 and 2.5L Jeep. No MPG gains or other miracles. Engines did seem to run a tad smoother with the FP but I believe it to be a placebo effect. When adding my new heads on my LS1 I tried some FP to loosen up the carbon on the piston domes. It did not budge the carbon even with a stiff bristle brush. I did the same when I had the heads off my Jeep. I let the CC's sit in FP overnight and hit them with a bristle brush the next morning. The carbon would not budge. I ended up using brass cleaning brushes with my dremel tool to remove te carbon.
I have a gal on FP left to use but after that I won't be buying anymore. The water technique has been proven to work.

SR77, it sounds like you assuming you have carbon buildup in the combustion chambers. If so, that's a pretty big assumption! You need to look in there and determine if there's any carbon or not.
If you've put a gallon of FP60 through there the chances are pretty good that your combustion chambers are clean and that the problem causing your pinging lies elsewhere (incorrect ignition timing, bad cooling system, etc.).
However, you'll never know for sure until you look!

Not sure if this helps, but I used to have a '91 Escort that tended to ping a lot. The only solution was to run 93 octane fuel. Anything less and it would ping especially up hills or when accelerating.
In my '97 Maxima, the owner's manual states that slight pinging under heavy load (especially in hot weather) is normal. I assume this is because the computer is trying to squeeze every bit of power with timing adjustments, and therefore is right at the edge of too little and too much. My manual recommends 91 octane, but 87 can be used with diminished performance.
If it is only when you're going WOT or up a hill, I wouldn't worry about it as it is normal. And accessories like AC can make it worse. But your computer should be keeping it within a safe limit and will retard timing if it gets out of spec.
If it starts doing it at idle or just cruising speed, then I'd think something is wrong. My first fix for that would be higher octane gas, and then possibly colder plugs if everything else was within specs.

When all else fails, just detour around all hills...
Could be a number of other things.
Poor cooling (common on the modulars, not sure about 302), incorrect timing, clogged EGR, etc etc etc.

FP60 won't help your pinging.
Check your ENGINE TIMING
Check your ENGINE TIMING
A dirty MAF sensor will cause overall leaner fuel mixtures which lead to pinging. Had this problem several times- carefully cleaned the fine wire, then mixtures returned to normal with NO PINGING or need for premium fuel. The light layer of dirt insulates the wire from the passing air, making the ECU think that less air is flowing by and less fuel is needed. Results in better power after cleaned, too.
