Which oil, exactly?

**pbxcomm** · 07-30-2017, 06:14 PM

Hello all,
I know this has been discussed in many threads and posts, but the more I read the more confusing and the more opinions.

I have a 2000 90HP Merc (oil injection). Can someone recommend a dependable oil and one that smokes less?
I read AMSOIL, MERCURY (3 different types) PENZOIL, there are others, I don't want my head to implode.

What I have read is there is a distinct difference between Merc oil in the light silver gallon bottle and the Merc oil in the dark silver gallon bottle. Is this factoid? Should I be running either?

Thanks..

Regards

Anything that is an approved NMMA TC-W3. Than it only depends how much you want to spend. JMO

Also excessive smoking my be caused by incorrect injection linkage adjustment as I have seen this a few times. Gary

Thanks for the replies..
Linkage is perfect carbs to pump, all is aligned per Service manual. I'm not experiencing excessive smoking, I really put it out there for input on a good 2 cycle oil. I use Mercury in the Light gray gallon bottle (from Walmart). I reads that this is an undesirable oil and I should use oil in the darker gray bottle. Can someone verify this? Is AMSOIL an option?

Please see above. Any TC-W3 rated oil will meet the requirements of the manufacturer, and is hence a good oil.

For low smoke, Alisyn is hard to beat. It is expensive, and I don't think that it is TC-W3 rated, but it is a high quality synthetic oil.

No lab verification, but I like the pennzoil XLF for the smaller 2 strokes.(200 and less) Seems to smoke less and leaves less carbon in the cyls. For the bigger 3.0 merc motors with the oil pumps the merc prem plus is my choice. Been doing this for many years with no oil problems.

POI.....our 225X PM smoked like crazy at canal speeds, tilt motor up, reduce exhaust back pressure and no smoke.

We use Amsoil HP Marine.

Thanks to all.. I'll stick with Mercury 2 Cycle, its safe and nothing here to convince me to switch.

I run around 28 to 1 in my mercury. keeps it from blowing up. Also keeps the mosquitoes away. Its like following an old muscle car on the highway.

Pennzoil XLF oil works just fine for me.

Pennzoil seems to work fine. .02

If you can get that oil at a low price, keep using it. If you stumble over another, cheaper, TC-W3 rated oil, consider switching. Again, that is why there is a TC-W3 rating.
