Fuel System Cleaner Questions

I use a fuel system cleaner every time I change my oil/filter.  I wondered about a couple of things:

1. Do you think they are really beneficial?

2. Does it do any good to do some full-throttle accelerations wth the  cleaners in to force a high volume of fuel thru the injectors and thus displace any debris that might have accumulated?

3. I was told, without proof, the cleaners do more good if you are running at highway speeds, than at normal city driving speeds.

 

Any thoughts or comments are welcome.

I'm sure they help some.  I use them too every once in a while.  As far as running at highway speeds, I don't know if that is true or not, but here's what I do.  I'm about 5 1/2-6 hours away from where my mom and dad live.  When we go on leave, I pour the fuel injector cleaner in, fill up right after, then drive the 5 1/2-6 hour trip.  In that time, it runs most of that tank of gas out, so it gets most of the fuel injector cleaner through over that 5 1/2-6 hours.  Makes since to me to run all the cleaner, or most of it, through all at one time.  ???

I usually run a bottle of Techron through in a tank before an oil change.  I don't think you have to force it through the injectors.  Fuel system is pressurized.  I would try to burn as close to a full tank of gas, though to realize the benefits of fuel system cleaner.  Highway speeds are recommended no matter if you use the cleaners or not.  Carbon has a tendency to build up more so under stop and go driving.  I use it a tank or so before an oil change because any removed deposits and by products from the fuel system cleaner will be trapped in the old oil and eliminated with the oil change.  Or maybe I'm just a bit wierd. LOL  :D  :D

I haven't used any of the bottle stuff as of yet.  I use chevron gas with techron religiously, as in every fill up, so I don't know if there would really be a benefit by adding a bottle of the stuff to a tank of gas that already has the same crap in the gas.  Just means I can take the few bucks by not buying the bottle to support my starbucks drinking habit... :D

Have used Techron in the Rado since near new and have developed no knocks or pings at all.  Usually about every few tanks.  A little $ now to save a lot later.

I just put it in every oil change or so, and drive normally until that tank is almost gone. It is good preventive maintenance to keep the fuel system and intake valves clean and reduce carbon deposits. Just read the bottle and know how many gallons your tank holds. If it is only enough to treat "up to 20 gallons" and you top off a 30 gallon tank with the cleaner, it will dilute the strength somewhat, I would think. I usually run it through at a stronger concentration, but either way its good preventive maintenance to spend a few now and save a headache down the road.

Much easier to reduce or eliminate small deposits now, and keep up with it than to try and start to get big deposits out later after they are causing a problem.

      AFM Disabler Question

      By KARNUT · Posted

      I’m doing an experiment on a vehicle I don’t have much money in. I’m going by the premise that after they last 100K miles they were no mechanical problems with assembly. Or defects with the parts. With oil changes by the minder for the first 127K miles when I acquired it. I quickly went through low mileage oil changes then settled on 5k oil changes with close to 170K miles on the vehicle currently. I did have the option to turn off the cylinder deactivation. I didn’t on this vehicle because in ECONOMY mode at least half the time. It should be a no brainer frequent oil changes are the key. The manufacturer gets away with the long oil changes with its severe service  maintenance. Just ask them what is normal.

      Hot air constantly blowing through floor vents, drivers side only?

      By baglie1 · Posted

      Even set to "recirculated", the air pushes out and is hot. I have noticed that sometime it doesn't want to switch between recirculated/vented air. Say it is set to Circulated Air and I want to switch to Vented, when I click the Vented button, it just quickly lights up/clicks and immediatly switches back to Circulated. It's done this a few times now. So maybe it is an actuator getting stuck? But then, that doesn't explain the hot air when everything is off does it?

      Gas Prices

      I wonder what the price is out at the coast, Big Sur or other out of the way locations as I bet they are charging quite a premium over the in land pumps.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Were you looking at the HD trucks on the GM website or the half tons as that makes all the difference. As far as I know there are only two options for the HD trucks and that is the standard 2 speed transfer case or the 2 speed transfer case that has the added 4 high auto feature and they put that transfer case by default into the LTZ and High Country although its optional in the LT and not sure if its available in the work trucks.    The half tons, that is where its been a total mess in my estimation for a few years now with most trucks below the top trim having the single speed transfer case as standard but with the option of having the two speed such as one would get by choosing the Z71 package, however then not being able to get the two speed transfer case with the towing package unless it was a higher trim truck AND had the 6.2 gas so one could combine the towing package gearing diffs with the two speed transfer case. Having said that if its a trail boss package then it gets the two speed transfer case but not necessarily able to get the tow package as it would depend on trim level and engine chosen. Believe me, people have bought the GM half tons assuming "of course it will have a two speed transfer case" only to find out after when they really pay attention to what they now own .... crap, there is NO low range !.    I don't believe Ford or Ram have gone that way yet with their half tons but like I say its been a few years now that GM has done this with the half tons.
