A call to FP users...

[LarryL]

For those using a steady dose of FP, do you, once in a while use a strong injector cleaner like ProGuard every oil change or so?

I have been using FP for a while. I use fuel system cleaner like techcron, redline, or regane. I get a small boost in MPG after using it.

I don’t plan on using LC anymore. I did not notice any difference between LC and Lucas UCL in terms of gas mileage. The FP/LC prices have jumped since I last ordered and lucas, techron, regane... are cheaper and readily available.

I have used Gumout Regane with my FP60. I figured a different solvent would attack different deposits, and it couldn't hurt, either way.
I am leaning towards Lucas UCL, for availability, a little mileage improvement, along with cleaners and being a top end lube.
It has been working well.

Since using FP, I have not used any other fuel injection cleaners.

Same as Titan X2

I *PRIMARILY* use FP60, but my tank currently has a whole bottle of Redline SI-1 in the car. Unknown history with 88k on the clock I figure it wouldn't hurt.

Before this I ran two shock doses of FP60 (6oz per 15gal tank).

If you run FP60 or Lucas UCL each tank, there is no need to use other cleaners.

I simply up the dose every once in a while - cheap to do, probably does nothing but make me feel like Im doing some more cleaning

 

[Shaman]

Yes I have. When I looked under the oil cap of my car, I knew that it would take more than maintenence doses to get the car clean. Just finished a molasoak, and have a good dose of FP left over with some Redline SI-1 in there too.

Just religious use of FP every tank. I noticed that when a friend borrowed my truck and topped it off without FP, more carbon was apparent on the tailpipe. This stuff definitely helps my truck burn cleaner!

 

[Dr. T]

No, nothing else. After 24k so far on brand new 2006 vehicle, the tailpipe has a light grey film...almost like the day I brought her home!

In the last 100,000 miles: Only when I have run out or forgotten to carry enough FP on a road trip. On my current vehicle ('01 DODGE Ram V8-318 with leaking intake plenum) I've used Redline once in the past 30,000 miles.
