Fuel line / injector cleaning additives

Who knows if fuel additive / cleaners do any good at all? You know what I am talking about. The shelves are full of umpteen different brands and prices. ????

 

Are some good and some not?

Are they all the same?

Should I just forget about all those and go right to Seafoam?

 

Its hard for me to believe that pouring 12 ounces of anything into 26 gallons of fuel can have much impact.

I don't know about Seafoam, but most off the shelf additives are "snake oil".

Run good gas and most likely, any cleaning agents are included, free of charge.

120,000 miles and never have run any gas cleaners.

I usually put 3-4 bottles of techron on 1/4 tank left and drive till the low fuel light comes on.

 

I have done the above in the past, and add another 3 bottles of the cheap stuff ....I've never had a problem.

Same here. Techron is really the only one that seems to make any difference. I run some through just before I replace the fuel filter every 10K. I also run almost a double dose.

Techron is the one. It works well, but like others, run a double or triple sode when you want to clean your injectors. I do this about every 10,000. Like above, I follow it with a fuel filter change.

Well since the 04 2500hd's dont have a fuel filter I'll have to run mine till the pump burns itself out..

 

 

 

 

Yeah, what another poor choice for a cost cutting measure! One tank of bad gas can clog the frame mounted filter. I would hate to do that with an in tank filter. Better not fill up at a station with the tanker there :cheers:

I agree, I used to teach a class years ago called fuels and lubes at a vocational school. In my research of additives believe it or not Techron by chevron is the BEST by lab chem testing, yes it is expensive but I trully believe all the rest are snake oil also. By treating your engine every oil change the injectors never get a chance to get cloged, once they are then its hard to clear them with just a bottle cleaner. At that point you then need a injector service. Also about fuel filters and adding cleaner I have a differnt take. If you add it with an old dirty filter it will do what it does and loosen all gum and dirt in filter. I have always only added my cleaner after changing my fuel filter. Just my thought.

What if you just went to Chevron to fill up all the time, instead of putting in the additives at regular intervals? Seems like a better idea...

Chevron is on GM's "Top-Tier" gasoline list for detergents and cleaners,they say if you use any gasoline on their "Top-Tier" list additional cleaners are not needed.

So I would say if you use Chevron gas all the time you don't need to use any additional additives or cleaners.

That stuff is not available everywhere and I have never been able to justify the 3 to 10¢ diff in price. Mobil is supposed to be good too but I can't get it here either.

I use "Champion" fuel system "Cleaner", yes, it is the one that has the "Champion" spark plug logo on it.

It works! I dump in a bottle, 16 oz @ $3.49 about every oil change, 3000 miles. I have documented that it increases my overall mileage by over 1 mpg.

I also use fuel that is 10% methanol, that keeps 100% of the carbon out of the combustion chambers and off the tops of the pistons.

have you tried just changing the oil and seeing if that, itself, is the cause for the mpg increase? :P

 

I'm faithful to chevron w/ techron, used it on my s-10 every oil change, when I pulled the intake to change out poorly engineered gaskets, 95k, the poppet valves on the end of the injector tubes looked brand new, pulled a friend's intake and they looked like the deireire of a french cow.

 

only thing I don't like is the 26 gallon fill up and inaccurate fuel gauge. :thumbs: --$$

      Lets Talk Z60 Suspension

      By ryan35205 · Posted

      Did the KYBs keep it the same height in the front? I was concerned that pre-assembled assembly would raise it up an inch to standard non-z60 height.. I guess which it would make the rake 1 inch instead of 2 inches.

      OCI, not when but why?

      Thank you for keeping the train on the tracks and for a thoughtful engagement. I enjoyed the reflection on a previous stance to refine and improve your position. I like that inquisitive flexibility about you Atlas.    No the process isn't sterile. Hundreds, perhaps thousands of miles of piping, vessels, pumps. Chevron, the people I worked for, were keenly aware that there is a market for what is known as their "ISOCLEAN" line of lubricants. These are lubricants that are the same as those sold bulk that are further processed by filtration to a level your particular application demands. They will filter and package and provide lab documentation as required. Do not kid yourself. Every gallon of oil that goes into a Chevron Turbine, reciprocating compressor, generator is prefiltered and tested before being charged. Lest wise it was when I was there in the plants I worked in.    There are requirements set by manufactures for the cleanliness of the oils used in their equipment. OTR such as CUMMINS has standards shared with customers on this. Commercial interest selling to Ma and Pa do, but don't share that information. Not even upon request but internally, they do exist.    The GM study sited, (Graph from Machinery Lubrication in previous post) only shows "relative" importance.  I find that fascinating. By constructing the graph like this they admit there are dozens of factors in engine life and via scientific method determined the effect of 'relative cleanliness' on engine life not in miles but in 'FACTORS'. This allows a certain amount of reverse engineering does it not?   They even provided some touchstones. Beta 75 as a reference point. Wonderful stuff!!   Smaller blenders CAN and some DO take the time and effort to do better than a refinery or large bulk blender, like Warren Oil, in improving the "in the can" cleanliness. No I don't have a list but testing could generate that information.    Again, but one of several levers we can pull to improve engine life. The simplest is keeping a clean work station while doing your own oil changes.

      Thank you. I'll give it a try

      I just spent the last 45K miles doing samples every oil change over more than a full year to get the data for seasons and break-in to broke in.    I found the same thing to be true. Something was always teetering on done or had stepped off the cliff long before the OLM was DOA. In fact, I found about a thousand mile difference between summer and winter. That is during the winter half the OLM was STILL too long. Even the severe schedule was to long in the winter.   Now having done the work I can say I was NOT DISAPOINTED. I saw nothing I didn't already know. Nothing my father hadn't already demonstrated in his 2K OCI's pushing dated iron on dated oils and weak filters to mileages well beyond 300K.   Building on his work through use of Lab testing it wasn't hard to find the correlation between 'sight/feel/odor, the things dad relied on, and test results. Use of current viscosity stable chemistries & filters has pushed that marker for my motors out to 3K summer, 4K winter.    So the early lies were 3K on conventional oil and the lie upon the lie was 7K+. turns out to be off by a factor of two.    So... it is true that modern chemistry has doubled the useful oil life. But the base milage that came from was off by double. It's how good lies work. Partly true, sometimes mostly true so that your meter isn't set off. It also means that non-shear-stable shelf oils are only now as good as the old oils were in their best case scenario.    So the question now is how do we improve on that? Thus the question into cleanliness among the other items listed in the post quoted below.    If this bores you, feel free not to participate.

      2027 Chevrolet Silverado: Official Discussion

      By newdude · Posted

      Is it though?  Like LTZ, not a high take rate.  Current Sierra has AT4, Denali and Elevation as its main bread winners.  Each trim accounting for 25-35% of sales for Sierra.  SLT makes up about 10-15% at best.        Like others have predicted here for GMC, it will be:   - Pro (equal to WT Chevy)   - Elevation (replaces SLE and SLT)   - AT4 (and X)   - Denali (and Ultimate).
