The Rock Oil is also semi synthetic but as long as it meets the TCW3 spec you shouldn't have to worry.

Amsoil and Lucas oils are good. Plenty of people use oil from Walmart and Sears etc.

Just like with car oils as long as it's in spec it will be ok.

Mercury say you can use premium+ oil which IS just a normal TCW3. I had a bottle of it and it looked and smelt identical to the rock oil.

http://www.mercurymarine.com/service...qs/optimax.php

It's all a load of crap just to get people to waste money.
[I]

I wouldn't but then unlike you I've actually run Opti's commercially for three years may I ask have you ever owned one, r how many of your mates had em?

Are you basing your opinion on experience or just good old bollox. If I had an ordinary technology two stroke I'd put anything in it that had TCW3 stamped on it

I've also had an oil pump go on an Opti when I was running it on TCW3 but I guess that's never happened to yours has it.

I'm interested that part of the justification for not using DFI is that Merc TCW3 looks and smells the same as Rock Oil....I should hope so they are both TCW3.

Has it ever dawned on you that your prime witness on the continuouswave website could be their equivalent of you According to that article DFI was no longer going to be available 5 years ago well that isn't the case so what else was accurate in it.

the replacement pump cost me over 800 quid

What does the Mercury manual say? I have asked this question several times and nobody has bothered to answer. Does Mercury say you can use the premium + oil - yes or no?

There is no proof at all that using a normal TCW3 caused your oil pump to go.

And i am NOT basing it on Bollox - just what Mercury say - or don't they know what they are talking about either???

"Can I mix the OptiMax oil with the Premium Plus oil that I have been running in my OptiMax?
Yes. OptiMax oil can be mixed with the Mercury Premium Plus oil that you have been running in your OptiMax."

This is direct from the Mercury website.

What alternative/equivalent 2-cycle oils are available when I can't purchase Mercury Marine Precision Lubricants or Quicksilver brands of oil?

If Quicksilver or Mercury Precision Lubricants outboard oil is not available, substitute another brand of 2-cycle outboard oil that is NMMA Certified TC-W3. The use of an inferior 2-cycle outboard oil can reduce engine durability. Damage from use of inferior oil may not be covered under the limited warranty. Always consult your Operation, Maintenance and Warranty Manual for additional information. Use the Bookshelf link on the Mercury Dockstore page if you need to place an order for a replacement manual.

Yes it does if you can't get the DFI and the engine will run on it, but it isn't recommended for long term use. .

It fkkd up when I was running TCW3 that's proof enough for me

Yes. OptiMax oil can be mixed with the Mercury Premium Plus oil that you have been running in your OptiMax."
you overlooked this bit

What is the advantage of the OptiMax/DFI Synthetic Blend 2-Cycle Outboard Oil?
The OptiMax/DFI Synthetic Blend 2-Cycle Outboard oil is specifically designed for Mercury Marine direct injected outboard engines. The additive package used in this oil is superior to the other oils we produce and formulated to provide an extra margin of protection in the OptiMax engines. OptiMax engines have additional pressures and temperatures over their carbureted and EFI counterparts.

*OptiMax Oil is ONLY for use with OptiMax Outboard engines and is NOT approved for use with EFI or Carbureted engines manufactured by Mercury Marine, nor is it recommended for use with engines from another manufacturer

thats from the merc website also, What is interesting is that you overlook the fact that the use of DFI oil in non Opti engines is advised against most strongly. This indicates to me that there is a difference between the two oils

My original comment was to an Opti owner and it was

Opti oil (DFI) aint TCW3 it's different, no problem with Rock oil for TCW3 compatable outboards but I wouldn't stick it in my Opti's.


I've got invoices to write and this is eating my time so I'm off. If you and your buddies want to stick it in your Opti's do so but please don't tell me it's the same oil as DFI......well you can if you want but I won't be listening

I did NOT say it was the same as DFI - just said that Mercury says you can use a TCW3 oil.

They would say that the DFI oil is better - cos they make a fortune out of it!!!

Prior to DFI oil being available, Premium Plus was the recommended oil for an Optimax, Mercury says it can still be used, but say's DFI is better.

Under no circumstances would I run Rock Oil in my motors, no particular reason why, other than that I have a large sum invested in outboards, and don't believe it's worth taking the risk of running what I consider an inferior oil just to try and save a few pence on each fill up.

It's more than a few pence and why should it be inferior?

I am certain Rock Oil is identical to the premium plus - remember Mercury do NOT make/refine/blend their own oil!!!

Would you use premium plus?

I've found the price difference to be small, perhaps I'm a better shopper than you. Inferior IMHO, as it's not the genuine article.

That would be IYHO, and like a lot of your advice, somewhat doubtful.

It's true that Mercury don't have their own refinery, but they have their own specifications.

And no, I wouldn't use it in an Optimax, but I do use it in my Promax's, as it's the recomended Mercury oil.

I'd probably use Rockoil in your rattly old Suzuki though, as I expect it's ok for old tech motors
