Sure, there is always hope for a fuel additive that really works,but thank god the vast majority do not hurt fuel systems and I have heard of no studies that the additive negatively impact the catalyitic converter.
  As a general observation, most of the people who visit these sites are looking to learn how to better protect their vehicles (expense) for best performance,low or no unforeseen breakdowns, and longevity. The mostly untold benifit to doing that is less emissions,and leaks into and on our earth. I do not want to sound like a tree hugger, but our kind of people do deserve a pat on the back for trying to do the right thing. Again let us know if you find studies or tests that would prove the benifits of fuel additives. I would be glad to read them.

I'm with you. I'll continue to occasionally use Techron Fuel System Cleaner (not the Injector Cleanor) once every 10-15K miles.
 
The bottle is very clear that it doesn't do anything to the converter. It also helps protect the fuel gauge slider from being affected by sulfur in the fuels. Some cars have had deterioration affecting the fuel gauge readings.
 
Techron is the additives which were in the Chevron fuel, which were the best at the time. I believe Chevron merged with Texaco since then. Texaco also had come up with a very good additive package. Since the additives were what was in good fuels to begin with, there's no reason not to use them.
 
If I felt I had an injector problem that needed cleaning, I would use a premium grade fuel fillup with the Techron to increase the effectiveness. If it's just prophylaxis, I toss it in with my usual regular. Much of my gas comes from Kroger and Mobil.
I don't pay any attention to the Top Tier advertising.

My New Boat Motor by basspro

Hi ALL, I did a search for out board motor issues and only found two. I have read and posted on this site quite a bit and decided to ask here an outboard motor question or two. Hope you do not mind giving me your opinions or maybe technical information for me to digest.
 As a short background my old out board was a two cycle and is now 21 years old. I have now bought into the new technology. I have bought a new 2008,EFI four cylinder,four stroke motor. (Mercury if it matters)
  As I read the information in the owners manual, it recommended only two oil products; Mercury or Quicksilver with some kind of service requirements(I assume marine) that I am not familiar with like the CI-4,CH-4,CG-4,CF,SL/SJ.
  My first question is there a conversion system to compare the two service requirement from marine to auto, if you know what I mean.
  My second question is I am going to replace the oil filter very soon and I will need to top off the oil. I want to start the process of switching over to full syn. and not the current blend the OEM recommends. What can I use that will meet their service requirements.
   As has been discussed many times on this site and others, there truly is a difference in oils,and additive packs. I want to find a syn. group IV ,or better oil to use that will meet and exceed the requirements of the motor builder.
   They also state that the required weight oil is 25w 40. I would prefer to go with a 0w40,0w50 or at least a 5w 40 for better flow characteristics,i.e. protection than the stock blend oil/add. pac.
   I need real help here at least to review information on these "new" kinds of motors. But I know in general a four stroke is a four stroke. Lets not get into the technicals to much other than to say, if the motor has roller tappets,solid tappets,odd cam profile, or some kind of timing belt or chain that needs a special lube, that I get, if that's the case.
   With a new motor I want to do the right thing for longevity and the least wear. I have less than 4 hours. Break in is, said by the book, to be done at eight hours.
   I want to change the oil and filter again then.
   Help me if you can or tell me what you would do. Thanks in advance.

Hello, basspro. I just joined a company with an engine treatment. I joined because the stuff they are selling works. Now, you don't know me from a toad, and I can appreciate your doubting attitude because I have seen hundreds of claims from oil and fuel additives. As this thread reflects, they probably do something, but not enough to get change out of the jeans time after time. But I found this one is really different. Tore apart an engine that had used it for 20,000 miles and was able to see the results of the claim. Ford Ranger 6 cyl 290,000 miles on it and no wear ridges in the cylinders. The surface was as they claimed - coated with a cermet surface. Any suggestions on how to get people like yourself to consider something that I see as a real benefit?

Wait I missed something. If the engine with 290K used the additive for only 20K, and then was torn down and showed no wear, how does it follow that the lack of engine wear has anything to do with the additive? And...How do you know the engine wasn't rebuilt prior? And did anyone run the same engine without the additive for the same # of miles and tear that down to compare?

What you're missing is that the engine from that Ranger may well not have had any wear ridges anyway. Case in point, I recently pulled the heads off of a 3.8 (that had only had oil changes every 10,000 to 12,000 miles) from a Dodge Grand Caravan with nearly 200,000 on the clock, and not only were there no ridges, the honing marks were still on the cylinder walls.
 
As for how to get folks to consider the products that you're selling, I'm thinking "good luck". Why? By simply using decent oil and regular maintenance, engines these days should easily last for hundreds of thousands of miles. With that said, I would quite honestly NEVER even consider any of these magic elixir products without a HUGE body of scientific evidence that proves their efficacy, and in more areas than just engine longevity too (i.e. measurably enhanced fuel economy, hugely increased oil change intervals, etc...).
 
Best regards,
Shipo

Yep - target on. I asked those and more. Kid who owned the truck was a long time customer of my mechanic friend who knew the truck. No formal stuff just - he knew the truck.The additive builds back the wear with cermet tech - new, but a few products out there. Blew the head gasket and at that high miles, decided to put a new engine in. Logical, buyt the cermet had repaired the wear. Hard to believe, but aI have seen compression repaired to normal after being really poor. No parallel test done, but I have seen dynamic results in over 100 engines and frankly am trying to figure how to get others to consider the "mechanic in a tube of gel" that reverses wear. But is does. Any ideas?

Wear ridges is just one of the measures, not the end all. Yeah - "How" is the question. I see it work time after time on those who don't know enough to be a doubter, but we older guys have seen too many claims with nothing to see in end results. Stuff works. Figuring out how to get an interest is the challenge.

Also an engine can have no ridge marks and be worn out anyway---worn bearings, worn oil rings, non-seating valves, worn valve guides, worn camshaft lobes. All a ridge line tells you is that the cylinder bore is not elliptical (egg-shaped).
 
As for "reversing wear", that is scientifically impossible in an engine IMO. You can gum it up for a while and boost compression a bit but other than that, there's nothing in a can that replaces metal that I've aware of.
 
Really all this is, is rather vague anecdotal evidence, which may have been sincerely passed onto you, but which is characteristically very unreliable and which proves....well....nothing at all. It's just a "story".
 
Unless this product can be tested with a blind group (non-additive engines, run under same conditions) and verified by an agency outside of the people who make the product, then it is not above suspicion.
 
I'm not surprised you're finding a challenge recruiting believers. There's no good evidence to support the claims being presented to us.
 
But if you have independent scientifically rigorous testing results, fire away, I'll read 'em over.

To say that I'm extremely underwhelmed by your anecdotal claims is an understatement. If you want anybody to even half believe what you're claiming, you're going to have to take a bunch of engines that have long gone 'round the bend, tear them down, make dozens of measurements each, reassemble them with no changes, run them 100,000 miles, and then tear them down for a second set of measurements. Failing that, most folks with any education in the area of art called engine operation and wear will consider your product just another "Me too" brand of snake-oil.
 
So, as Mr. Shiftright kind of suggested, please provide us with some scientific back-up to your anecdotal claims.
 
Best regards,
Shipo
