Re: Oil Additives (DO NOT USE)!!
Quote:
To let everybody know many of these oil additives are made from whats called "base polymears" or extreme pressure additives. They ARE in all motor oils to adjust viscosity and wear characteristics .... BUT in engineered ratios for the weight and use of the oil.... Direct from a Mobil Oil engineer I got involved with on a project back in the 80's. The problem becomes when the "more is better" crowd get hold of them and do not use them correct. Splash systems should not need more than what is in the correct weight oil that the MFG. calls out for. You may have other problems in the motor like bearing rattle, lifter noise etc. Many old car dogs that sell used cars used to like "motor honeys" because they quiet down a motor on startup. By using in a splash system you are changing the viscosity higher and you will not get proper lubrication in a filtered or non-filtered system. I also have seen small block Fords twist the oil pump drive shaft because the oil was to thick for the cold temp on startup. |

Re: Oil Additives (DO NOT USE)!!
I disagree. Most oil related failures are caused by misuse. Too much oil, not enough oil, etc.
If carts used a high performance 2 cycle engine with ultra high rpm and top shelf load a special $30.00 a gallon oil might be called for but the HD engine is happy with good quality oil and TC-W3 certainly meets this requirement. The two cycle oil debate will go on as long as there are 2 cycle engines. There are many articles on the net on this subject and I don't think there are any that say that TC-W3 oil is not good for air cooled engines. I am working on 7 to 8 years on my HD engines with no oil related failures. That is good for any engine that is used daily in my vineyard and around my farm. However opinions are like _____ everyone has one! I think you should use the oil of your choice. The are all good. No offense intended, just my opinion after working on 2 cycle engines of all types since 1960. |

Re: Oil Additives (DO NOT USE)!!
I installed a new Yamaha 357cc motor (4 cycle) in my G27A Utility. Runs great after it burned all residual oil out of exhaust. Old motor was a smoker!
In response to another thread, someone suggested adding zinc to the oil. ??? |

Re: Oil Additives (DO NOT USE)!!
Oil Additives are not good! Usually if a 2 cycle engine smokes it is burning too much oil. On motorcycles the auto oiler probably needs adjusting and not oil additives.

Re: Oil Additives (DO NOT USE)!!
Do not put any additive that is thick in any engine that uses a splash system to lubricate (typically any engine that does NOT have an oil filter/no oil filter usually equals no oil pump). And I would NOT use any oil over 10w30. Example: take whatever you are thinking of putting in your engine, pour it into a cup about half way, take a popsicle stick and see if you can easily splash or fling any of it outside the cup. If not, don't use it. This is a great test because you get a free popsicle before doing anything.

Re: Oil Additives (DO NOT USE)!!
I don't add MMO to the oil but I've seen with my own eyes what it can do for removing carbon in a diesel. I don't believe in miracles in a can but this stuff is pretty impressive when used as a fuel additive. Also use it in my air tools and as a penetrating oil.

Re: Oil Additives (DO NOT USE)!!
Zinc Phosphate is the additive in oil that's the best anti wear compound. It was added in large amounts in the old days before unleaded gas and catalytic converters. It has limited use nowadays because it will load up the catalytic converter.
