I know there are probably widely varying opinions on this, but thought I would ask anyway:
I have a 2004 Mercury 90 hp 2 stroke - not the Optimax, just the 'regular' two stroke. I've always used Mercury Quicksilver 2 storke oil as the manual recaommends, but when I see it selling for around $26 a gallon and see Penzoil 2-stroke oil on sale for $12 a galon and Cabelas brand on sale for $10 a gallon I wonder if I'm wasting my money paying for the Quicksilver? Is there really a difference?
with the standards oils are "made" now i'd bet the penzoil is just as good. ole barnical bill can tell you
Yes, it is worth the money. I used to blend them, but not any more. Pennzoil ain't bad, just don't use that Wal-Mart crap! What I've found out is the Merc oil lessens the effects of fuel injector cleaners gumming up the rings. Just make sure its marine and not the other 2-cycles oil, which burn at a higher temp. Really its "Pay now, or pay later"
Mechanics and parts cost alot more than the oil you will ever burn. Why even take a chance. Merc oil has more additives for wear prevention.
If you want to save money, take a pbj and not the mc donalds with you to the lake.
Merc probably buys their oil from someone like Penzoil and rebrands it. I'm sure Merc has a crack team of mechanical and electrical engineers with years of experience in outboard design. And I'm sure Penzoil has a crack team of petroleum and chemical engineers who have years of experience in refining and blending oils.
i bought some prem plus merc at bass pro at nashville todat for $19.99 a gallon
if it meets the specs for the engine, tcw or twc 2/3, and a brand name such as Pennzoil, etc., should be good. Merc doesn't have/own a oil refinery to make their 2 stroke oil, someone else does. Could be the same place that makes the walmart brand as well.
That's the way gas is here, there are only 2 distributors in town and the gas is blended to order, additives and what not for the different brands.Quote:

X2 on everyone reading this article. Every test I have ever read comes to the conclusion that as long as it meets the spec for manufacturers recomendation you are good to go. The only exception is high RPM racing type engines and then they reccomend running pure synthetic.Quote:

I know Im not spelling this properly, merc adds more meryberyllium in their oil for added wear protection, mobile oil makes the oil for merc. If any of you can remember the rare earth metals please chime in and correct the spelling, Im getting too old to remember anymore, but really I just dont care
But I do use the Pennzoil in my lower units for about the last 10 years.
My 2 cents worth, I have used both, for some reason the pennzoil smokes more, so I use the merc oil exclusively now. I have 4 outboard engines.
When I worked in a marina many years ago, we took several brands of oil and mixed them together in a jar. We did see some separation between the different brands. I would guess that pre-mix engines wouldn't need the same brand every time, but I'd pick a brand and stick with it if the motor uses remote oil injection.
