Where is the best place that I can buy some outboard 2 stroke oil from. Would prefer to buy in bulk like a box of 10liters + or so.
Does not have to be an expensive brand.

I'd be interested to know what you define Cheap oil as? None of it is cheap at the moment. PM me if you dont want to name brands on line

Well $92 per 1gal is expensive and $38 per 1gal is cheap somewhere in the middle would be a good idea, I sell Sierra oil for $49.99 1gal OEM oil is generally from $55 - $92 1gal retail, depending on what oil you need (e.g. ETec need the $92 oil, HPDI need the $79 oil) A conventional two stroke would use oil in the $40 - $60 1gal bracket  ------------- The Mighty Waikato http://www.facebook.com/pages/Kings-Marine/100476476662857?%3Fref=ts |

Slightly off subject The auto industry is rife with engine failures due to oil quality. Caused IMO by the removal/reduction of ZDDP (Zinc, which is an excellent anti-wear agent) in the oil, because zinc damages the newer style of catalytic converters (which are used in the exhaust system to meet emissions standards) it has been fazed out of mainstream oils, this in turn has lead to premature engine failures that have not been experienced before. The oil industry have started adding alternatives to the oils to try and remedy the situation, but it just goes to show that oil isnt just oil. Always research the product you are going to use ------------- The Mighty Waikato http://www.facebook.com/pages/Kings-Marine/100476476662857?%3Fref=ts |

| a good 2 stroke oil be synthetic 2 stroke oil it prevents carbon build up in the ring grooves eliminating stuck rings & compression loss |

I was under the impression anything meeting TC-W3 standards was all good..  I'm using Pennzoil premium plus TC-w3 , do you think I'll be ok..? ------------- keen fisho |

without going into all of the tech issues of the two stroke oil. TCW 3 standard is the required spec for oil injected two stroke engines, some manufactures have a higher standard for their oil but there is no higher spec for two stroke oil, so it is still labeled as TCW 3, but in some cases it will perform better in a two stroke engine than others. Like car oil you can buy 20W-50 at Repco and you can buy 20W-50 from say Castrol - both oils are the same rating and both oils will go in your car, but both oils are not the same !!!!!! What is even more confusing is that some synthetic two stroke oils do not meet the standard for TCW 3 oil for example Optimax DFI oil is not recommended in a normal oil injected two stroke engine I notice BRP XD100 is also not labelled as being TCW 3 ------------- The Mighty Waikato http://www.facebook.com/pages/Kings-Marine/100476476662857?%3Fref=ts |

if you read of what other have to say from over seas it a known fact that 100% synthetic oil is used & recommended , the fact that it gives of less smoke witch is a cause of carbon build in the motor , & does not foul the plugs , is an advantage , witch means it burns clean , tw3 they say is good but most prefer synthetic 100% grade here you will find every thing about tw3 oil http://forums.iboats.com/showthread.php?t=481289&highlight=zinc+stroke+oil |

Sorry Durban clearly printed on Optimax DFI synthetic oil bottle " it is not intended for use in any engines specifying a TC-W3 oil" In fact when you use a Mercury Optimax high performance engine you must use the standard TCW3 oil and not the correct synthetic Optimax oil because of lubrication issues. Yes I agree synthetic oils tend to burn cleaner than a mineral oil, but not at the expense of lubrication. I personally have seen engines destroyed using synthetic oil, and when your talking a 30k engine it can be an expensive mistake. ------------- The Mighty Waikato http://www.facebook.com/pages/Kings-Marine/100476476662857?%3Fref=ts |

| I have been using valvoline but have found in my new engine that it is smoky, and seems sooty at the prop hub, so will be swapping back to yamalube which is dearer but seems to burn cleaner. |

| kingsmarine can you use yamalube on mercury 2 strokes? |

Yea you can, but why when it is more expensive than even genuine Mercury oil ??? I prefer Sierra oil as it is a semi synthetic (best of both worlds) and has a reduced smoke formula, also a very good price pm me for a customers video of Valvoline vs Sierra oil - excessive smoke in a Yamaha 90HP ------------- The Mighty Waikato http://www.facebook.com/pages/Kings-Marine/100476476662857?%3Fref=ts |

Only time the engine smoke's is on start up, then nothing at all, all day unless i stop then start again. Sierra oil is it built for late 90's 2 strokes?

| Yip, I don't understand why people say two strokes are smokey?... they simply are not, not modern ones anyway IMO. As above, a small amount on startup and that's it, and the odd whif at idle, but not smoke, I'd say something other than oil is causing smoke like an over-rich mixture, worn rings etc?... or perhaps I never notice it in wellington as it's usually so bloody windy! |

| That is exactly what happens, just a wiff of smoke that is it. the smokey side is the start up side of thing's that people hate..other wise they ok if looked after...not many of us can afford to go out and finance a 20K engine, then again people will say then how do you go fishing if you can not afford to pay for a engine..some of us make do with what we have for now.If i had 10 K i would get me a honda 90 and be happy as a virgin in a whore house.. but i don't..and so i miss out on fishing most day's or months..that jetski is looking better n better...... |

I find that valvoline at low revs (1200-1400 trolling speeds) to be quite smoky compared to yamalube. At high revs you wouldnt notice the difference.This is on a brand new 38hr old yamaha 60hp. |
Posted By: Spaz
Date Posted: 02 Oct 2012 at 5:01pm
| I'd agree with you In.Funds. I also find Valvoline, and others smokey at low RPM's compared to the Yamalube. I have always run yamalube due to getting an awesome deal when I brought the latest boat and got it in bulk. However, now i have finished the bulk i'm trying other brands as Yamalube, although being a bloody good oil, is freckn expensive at the best of times. |

| got the sierra on-board now. i'm thinking at high revs you wouldn't know about any smoke anyway. we'll see how this oil performs whilst drifting around looking for fish. my motor isn't particularly smoky, any reduction will be a bonus. |

Are you saying to not use optimax dfi oil in a optimax engine which it was designed for and which mercury insists you should use?wat oil would you recommend for an optimax? Dfi oil i very expensive and i only Use it because I thought i had to or the engine would be damaged. |

dunwurkn If you have a Optimax high performance engine (not to be confused with a standard Optimax engine) you need the standard TCW3 oil rather than the correct Optimax oil you would run in a standard Optimax engine probably my point was that sometimes the oil that is needed for a particular application can be different, even though it is the same engine and sometimes the correct oil to use isnt what you would think it is i.e. the full synthetic Optimax oil is no good for high performance use as it doesnt lubricate as well as the standard TCW3 oils, which goes against the grain of normal thinking that synthetic oil is better than mineral or semi synthetic oils. Part of the reason for the special Optimax oil was to help with the spark plug fouling issues and it burns cleaner for exhaust emissions. ------------- The Mighty Waikato http://www.facebook.com/pages/Kings-Marine/100476476662857?%3Fref=ts |

Thanks you very much for the response km much appreciated i think i understand what you are saying now. How can you tell a high performance optimax apart from a normal optimqx. What is the engine you commonly see on boats in nz? Or is it the same engine and the application it is used for which makes it high performance? |
Posted By: Kings Marine
Date Posted: 18 Jan 2013 at 8:08am

It is the same engine with stronger pistons and conrods there are quite a few of the high performance Optimaxs in NZ, the cowling has either "XS" or "Pro XS" in the graphics, apart from that looking at the engine you can not tell the difference Generally a fishing boat will have the standard Optimax and the ski boats have the high performance Optimax ------------- The Mighty Waikato http://www.facebook.com/pages/Kings-Marine/100476476662857?%3Fref=ts |

A dude in the Tron has Pennzoil Premium Plus @ $50 a gallon jug + P&P. Seems a fair price for a regular Opti do you think KM? Americans can get the same oil for $9 on special. All warranties should be honoured if the correct API spec is met,regardless of what the engine manufacturers say. How many O/B manufacturers have their own oil refineries? They place an oil spec to tender,then place their own logo on the jug. A Bill passed in the US Congress stated that if any manufacturer demands that only its branded consumables (ie oil) are to used exclusively for warranty reasons.Then the manufacturer is to supply the customer with that product for FREE for the warranty period. This Bill became law there in 1973. Well thrashed out in the courts. You should see an oil spec and not a brand of oil in the owners manual for every new O/B sold in NZ as well. Cheerz |

"Recommended engine oil. YAMALUBE 2-stroke outboard motor oil" And then it says: "Recommended engine oil: TC-W3" ------------- Semper in excreta sumus, solum profundum variat.... |

My bad.But you are still covered if you stick to the recommended oil spec... The yamalube is a product/profit line for yamaha exclusively,is it not? No money for yamaha by using another oil brand. A marketing ploy used by nearly every O/B company. |
