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. |

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. |

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.

Replying to: niknmax (Mar 21, 2009 5:32 pm) 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

Replying to: shipo (Mar 21, 2009 5:47 pm) 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. |
