? for fulltime MMOers and maintenance dosers

[NMBurb02]

Do those of you who use MMO, maintenance doses of SI-1 or other FSCs, or any myriad of other additives (MMO/TC-W3 mix, acetone, xylene, etc.) at every fill up also do a traditional full dose FSC treatment periodically?

I've been playing with adding TC-W3, MMO, and a combination of the two in both vehicles (more for poops and giggles than anything else, nothing scientific) but wondering if I should toss in a bottle of Gumout AIO or Techron Concentrate every 3,000 to 5,000 miles to make sure everything is nice and clean.

Yes I'll toss a bottle of FI cleaner in once a year, usually before I change the oil for the winter.

I've got a vacuum line mister on my 5.0 filled with mmo,and use a tc-w3/acetone mix in the fuel of everything I own that burns gasoline. I could go on and on about how well my compressors run or the mustangs runs,or how my girls van runs,or the engines I ended up tearing into using this mix in the fuel consistently and how clean the piston tops and valves were but I've already written it out more times than I care to count.
5 ounces tc-w3-1 quart acetone per 25 gallons fuel. Try it.

Im not full time as in every fill up, but every now and then i throw some in at fill-ups, I 100% always add techron before leaving town on a vacation/roadtrip. My dad always said "fuel system cleaners work best durring extended driving" so i do it.

He was wrong. They work best in a stop and go type environment. And periods of sitting with the treatment in the fuel lines and injectors.
A few minutes of flooring it near the end of the tank doesn't hurt either.

Call me paranoid, but anything that is mass produced has variations in production runs.
This includes fuel.

I've played around with dosages of Sta-ble, MMO, TCW3, and multiple types of Fuel System Cleaners (I think I like Redline the best).
I've even done 1 fluid oz of each per fill up for quite some time and had no issue.

After 192,000 miles on my Ford Taurus I had to replace the Fuel Pump, a gasket on the fuel pump had gone out and the vapors were quite strong outside the vehicle.
If this was due to the cleaners, or just wear and tear I don't know, but I have had no other issues with anything.
The fuel pump and related sock filter came out Brown and pretty gross looking, while it still worked the gasket that surrounded it and kept it in the tank was going out. The new one was white and pristine looking.

I do know that about 5 years ago when I decided to replace the fuel filter on Everything I own the Taurus's fuel filter was almost filled to capacity with something that looked like sand.

The only thing that I have found on my 1998 V6 F-150, 2004 Nissan Xterra, and 2002 Ford Taurus is that just about any fuel additive will do more good than bad.

I can't imagine that Gasoline, as it is refined today, holds anything but the minimum quality controls in place.
If you want to drop an extra few dollars every 3,000 to 5,000 miles on a fuel system cleaner. Or you just want to play around with dosages every gas tank of a few fluid Oz of this or that. I see no harm in it.
That being said, I do see a cleaner fuel system in your future, either way.

I use MMO in the gas, always, when fueling my Jeep. Since it always has MMO in it I do not use other fuel system cleaners.

Im not saying your wrong, but your the first ive got this from. I see the logic in what your saying.. Id like hard proof one way or another.. All the bottles say if memory serves is to fill up your tank when adding FSC.

TCW3 + small maintenance dose of techron in every tank.

Think about it. On the highway your rpm tend to be low,so is the amount of air going through the engine.
In a stop and go environment you get periods of higher rpm,which equates to more air and fuel and more velocity. You also get a richer running condition which helps the carbon deposits get saturated and easier to remove.
And as the vehicle sits the fuel additive sits in the fuel system,helping to dissolve deposits.
This is common sense as far as I'm concerned.
The varying rpm and fuel pressure will clean a fuel system far better than setting cruise control driving down the highway maintaining a consistent rpm.

I havent' seen anything that said stop-and-go is better than highway driving for gas tank fuel system treatments, but I thought Chevron's paper showed that the more starts on a tank of treatment, the better because when the engine is off, that is when the PEA gets to soak into deposits and loosen them up.

I personally only run my one time treatments like Gumout AIO when I know I'll be doing lots of short trips.

 

[OtisBlkR1]

all good information.

There's your answer!
