Yamalube is the reference oil used for NMMA TCW3 outboard testing. <br /><br />Oils are tested in outboards, engine parts evaluated for wear, carbon, etc., and the results are compared to the reference oil's results.<br /><br />I called Yamaha directly after buying my boat in 2001, spoke to a factory tech. I asked him if I had to use Yamalube to keep the warranty up. He told me that any TCW-3 oil was fine and Pennzoil Synthetic Blend was a good choice, but the 100% synthetic oils were not recommended in the hpdi motors.
Warren Distribution still makes the Super Tech TCW3.Wallyworld changed the container colors of their SuperTech. Anyone know if it's a different mfg from previous color?

[/QB][/quote]<br /><br />The NMMA site lists one of the Walmart TC-W3 oils as being made by Shell oil, sense the buyout of Pennzoil by Shell the likly hood is that it is a pennzoil of sorts. Just because it may be made by Pennzoil doesnt mean its the same as Pennzoils 2 cycle oil.<br /><br />It then goes on to list the Super Tech as being made by Warren, evidently there are two different ones.<br /><br />Most of the automotive Super Tech oils are being made and bottled by Warren though.<br /><br /><br />NMMA siteWallyworld changed the container colors of their SuperTech.

OilDoc,<br /><br />I've read your posts since you came aboard and they are pretty well researched. However I have to question your above quote.<br /><br />The TC-W3 Certification Tests use NMMA XPA-3259 reference oil and the NMMA 93738 reference oil, depending on which procedure is done.<br /><br />Yamaha 2M outboard oil is not the reference oil as it does not score the pistons (up to 15% is allowed with the reference oil) and it contains a large percentage of PIB, which is not in the NMMA reference oils.Originally posted by TheOilDoc:<br />Yamalube is the reference oil used for NMMA TCW3 outboard testing.
I can assure you that Yamalube was used as a reference oil. Chevron and other brands were also used as reference. Reference oils are evaluated and given alpha-numerical designations, like the ones you have provided. The NMMA and testing facilities do not list reference oils by name-brand.<br /><br />It is well known in the testing industry that Yamalube has been used as a reference oil. In fact Yamaha uses that fact to market their Yamalube.<br /><br />By Yamaha:<br /><br />Naturally, any outboard oil should be TC-W3 approved. Yamalube oils are so good they have actually been used as the test oil for many of the TC-W3 ratings! That means that all other TC-W3 oils had to measure up to our high standards. <br /><br /> http://www.yamaha-motor.com/accessories/apscitemdetail/3/121/4039/All/1/detail.aspx <br /><br />Yamaha realizes other brand TC-W3 oils meet or exceed their own oil, since theirs is used as a reference. This is why their factory tech supports using other TC-W3 oils as mentioned in member BillPs post. <br /><br /><br />The TC-W3 Certification Tests use NMMA XPA-3259 reference oil and the NMMA 93738 reference oil, depending on which procedure is done.
I am not aware that polyisobutylene (PIB) content is a defining factor for a reference oil. It would be appreciated if you would share any information you have concerning polyisobutylene limits of reference oils. I dont think I have seen that.<br /><br />If I understand you correctly concerning the 15% piston scuffing, you are referring to the TC-W3 Mercury 15 HP 100:1 detergency test. If I recall, that particular test does allow a 15% piston scuffing limit for the candidate oil, but it does not involve a reference oil in any way. Please correct me if I am misunderstanding your statement.Yamaha 2M outboard oil is not the reference oil as it does not score the pistons (up to 15% is allowed with the reference oil) and it contains a large percentage of PIB, which is not in the NMMA reference oils.
