Optimax oil, where and how much?

[Phil Chitty]

I'm looking for a regular supplier of opti oil for my Merc 150 opti.

Where do others go and how much do you pay for a bottle?

Use Rock Oil instead - it's a lot cheaper and looks identical to the mercury oil. it meets all the proper specs as well.

It is semi synthetic - called MP3 sport for some strange reason!!!

Oh, thats okay then.

Optimax outboards don't use much oil. Why risk knackering your outboard because you put in the non-recommended oil? Doesn't make sense to me.

I guess it would also void any warranty claim if the engine is still under warranty.

Who says it's not a recommended oil? Mercury don't!!! They say you can use a TCW3 oil. They recommend 2 of their own oils - the premium plus and the optimax. The Rock oil falls somewhere between the 2.

"Yes. OptiMax oil can be mixed with the Mercury Premium Plus oil that you have been running in your OptiMax." Quote from Mercury!!!

I suppose if you have a Toyota you only but their oil? Or a BMW you only buy BMW oil?

Merucry etc make a fortune out of people who think they can only buy the own brand oil. Remember Mercury do NOT refine their own oils!!!

Nope as long as the oil is to the correct spec which it is!!!

Oh I give up - carry on buying expensive oils whilst I buy Rock Oil at 1/4 the price.

Yup use it all the time. Great company to deal with as well. I bought a few 25 litre drums and a box of 1 litre bottles which I keep and refill.

I was using a comparable grade oil on my Opti last year when I ran out and could not get the Mercury branded product on my round britain. On my return my engine suffered a major internal failure caused by who knows what but was still under warranty. The workshop told me that there was a differant type of oil visible in the reserve tank and as it was differant colour and I explained the reason, they chose to ignore this and put it through under warranty but did say that Merc would not have validated if they had mentioned it to them. I ama good customer and I think they took a 'view' on things. So whether or not its the same product you could still be in trouble at which point a minor saving on oil would seem a bad deal.

Also you mention BMW oil, same goes. BMW state that warranty claims could be rejected on the V10 M series engine unless one specific brand is used.

As much as I appreciate the advice Codders, I think I'll stick to the real stuff.
I've been caught out before using non-approved oil in a car and got a huge bill for repairs.

I'm paying about £30 a bottle at the moment. Anyone know where I can buy it cheaper?
