FP60 success story... how?

[BatmanLS1]

In recent months I've had some issues with my Buick while driving along at highway speeds. It would sort of stumble or miss I suppose while travelling at a constant speed. It started to get worse and the car would accelerate unevenly in all gears. The car would idle fine though.

I sort of came to the conclusion through process of elimination that it was probably fuel related, somehow.

For the heck of it, I tossed a shock dose of FP in the tank the other night. Then drove into work. Noticed the car didn't miss as much, but always seems better in the morning. Then, coming home yesterday in the hot weather (usually worse), I noticed the car was driving almost normal again. It felt like it was slightly missing, but not nearly as bad as before. I am still going to change the fuel filter (original 115k) to see if that changes anything.

But, what exactly did FP60 do? What do most people think is the issue? Was it a clogged somewhere (injector, filter, etc), but now being dissovled? Is the car detonating from build up, but FP60 is curing? I have no clue.

Although FP has eased this situation ...I'd look at something like bad wires maybe.

 

[rauljimenez]

Yeah as gary said, look for the wires. I would also change that fuel filter, you said you got 115k miles on that fuel filter ouch man.

 

[MolaKule]

Deposits on spark plugs maybe?

I'd also check the Spark Plugs and gapping of same.

I had similar problems with my '86 Buick Century with the "pre" 3800. Shell gas greatly reduced the stumble off idle and the occasional miss at highway speeds. The wires were the original factory wires with 90k miles. Because the rear plugs were such a pain to change I ran out of time in changing the front wires. All three rear wires were frayed. All six of the plugs were replacement AC Delco plugs and looked fine. No change in the way it ran. Changed out the front wires and it ran perfectly. The funny thing was that the front wires looked fine.

Any car with the original fuel filter can cause a lot of problems, especially with that mileage.

Note that the GM DIS ignition systems are waste spark style system that runs very high voltages and fire twice as often as a conventional ignition. These engines can be very picky as to what plugs you can run. Bosch and other non AC Delco platinum plugs can cause a lot of problems. AC Delco platinums can make a great deal of difference running smoothly from my experience.

Also do not forget to air filter and the PCV valve.

I've been on the prowl for FP answers lately despite vast searching and reading. I'm curious about if it's necessary or just 'a good idea.' It seems like most people swear by it while few others are just slightly reserved about it being so necessary. Who can I believe?

FP60 is widely discussed here, but can anybody say for certain that it will only good for my car in the long run? Who has seen a fuel mileage increase & how much? I also want to be sure that it will keep my valves really clean (int AND exh).

I keep a detailed fuel spreadsheet, and I can't wait to share my results on that. Believe me, I want it to be the right stuff and to help prove it too! Thanks.

I keep a detailed fuel spreadsheet too.

Not only does FP60 does it's job as advertised, but there's some positive side effects that I haven't seen people write about. For example, in my car, which I've been using FP60 for about 13 months (25K miles), the PCV valve is squeaky clean after 10K miles! I usually replace the PCV at this point, but there's no sense in doing so.

To me, that means that FP60 is keeping all that nasty carbon in check, allowing the cleanest possible operation that this vehicle can offer.


In my other car, the one powered by Honda's 3.5L V6, EGR valves have a nasty habit of needing replacement. Using FP for the last 20K on this car (it has 26K on it) will hold that EGR repair at bay for a long time, maybe even indefinitely.

You won't ever see me at the dealer for their "special" fuel injector cleaning for $89.00+. It's never needed when proactive car care is in place. That is, using FP/LC.

"Who can I believe?"
People like myself who have seen first-hand the benefits if using this product by first seeing that it was used in a fleet. To me, fleet usage tells the story. If a company can step up to the plate and use the product long term and have success with it, then I should be able to as well. After all, they have a LOT more to lose if the product isn't all it's cut up to be, right? That's my thinking about it...

Using LC, the oil isn't even dark at 2500miles into the OCI (4 cyl old Saturn).

I'm thinking I have a win-win combination on my hands.

Is FP/LC needed? No. Is it worth using if you want to get the most MPG and keep the engine/fuel system squeaky clean for 300K. Without question, yes.

I posted a similar story a few months ago involving a friend's car. Some posted skeptical remaks. However, I stand by my story.

I have experienced an increase of 2-3mpg since I have been using Fuel Power.

I view FP60 as a necessity, generated by the lack of consistent levels of detergent adds in various gasoline brands.

The recent Top Tier gas specifications are an indication of the issue surrounding US gasoline and the historic lack of minimum amounts of detergents.

And with the ethanol blended gas in the Chicago/Milwaukee market, a yearly application of some brand of fuel system cleaner is a requirement for maintenance of the injectors & inlet valve deposits.

I don't see how FP60 could clean your PCV. No fuel goes through the PCV. LC maybe, but not FP60.

2 MPG in my I30 atlease, i love this stuff........

"I view FP60 as a necessity, generated by the lack of consistent levels of detergent adds in various gasoline brands."

I agree and have been saying that for some time. It is an affordable and effective response to the lack of solvency in todays fuels that is amplified by hot running engines.

Kang, if the vapors of FP or LC get to the PCV system and having seen TNS's oil analysis they are, it will lower insolubles and inhibit that blowby debris from adhereing to choke points like the PCV valve. Fuel soot is indeed a contributor to increased levels of insolubles in the PCV system.

He has had consistant issues with his Saturn rings sticking or not getting a good seal.

In addition to spreadsheet records I highly recommend oil analysis to verify the effect.

For instance in some engines a FP60 and Auto-RX maintenance dose regimen may be all that is needed.

I use both products and when used based on testing results they can be optimized.

Lack of solvency and lack of lubricity. Same effect to some lesser extent from MMO.....let your arrows fly. (I still think FP is better, ok?)
