Quicksilver oil

[burleytog]

Is the Quicksilver at WalMart the same thing as Mercury oil?  Need some oil and the closest Merc dealer is about 60 miles away.

[Jimzee]

The guy who services my boat told me the only other oil I could use in my Merc engine without voiding the warranty was Quicksilver.  I am gonna say yes.

[burleytog]

The stuff says Mercury in small print on the back.  The tank on the engine is full, but I plan on running at least a tanker truck through the boat next weekend.   ;D

BL for what it's worth, two stroke oils are pretty much all the same.  I mix and match them all the time.  Today I put 13 oz of Quicksilver and 13 oz of Pennzoil into my tank.  I've been doing it for several years.  My 89 Johnson/Evinrude still runs like a top.   There will soon follow a number of posts telling you what an idiot I am.  ;D

As long as your not mixing synthetic with non-synthetic you will be fine(some synthetics don't play well others). BUT if the motor still has a warranty on it I suggest going with the recommended oils.

I bought my boat with a 90 Merc 2 stroke from Bass Pro.  The boat center personnel told me QS oil is fine, actually recommended it.  I have been using it for three years with no probs.

That's all I needed to know.  Thanks.

The can not say that. They can tell you that you need to use tcw III oil. They can not tell you, you need to use a particular name brand.

please refer to the Magnuson-Moss Warranty Act

Quicksilver is the Merc. label. However any quality tc3 oil is fine. Merc. is extremely proud of their oil. You can tell by the price.

How many times have I heard the BS that all TWC-3 were the same.  If all TWC-3 oils were the same, the manufactor would not be so specific specific about whose oil you can run to maintain the warrenty.  They don't do that just because they want to sell you their oil, they do that because they are not going to be respossible for the damage you do to your motor with some of that cheap crap people want to buy because they are too cheap to buy good oil for their very expensive outboard.

I've been working on outboards for about 40 years and have seen too many time what the inside of a motor looks like that ran cheap oil.

I have never, and never will run an oil because it's cheap.  For those that have the mindset there is no difference in TWC-3 oils, just don't know what they are doing to greatly shorten the life of their motor.   Of course, most of these probably won't put 30 hours a year on one so they can say, "I've been running this oil for 10 year and never had a problem" so after 15 years the motor is junk but it's got less than 500 hours on it.   I run that in three years.

I've pulled commercial motors down that had 1,200 - 1,500 hours with the manufactors oil that had less wear and were cleaner inside than motors with 500 hours on cheap oil.

If people want to run the cheap stuff, it's their motor so they can run 30W motor oil if they want.  It just erk's me when they try to rationalize their using the stuff by saying all TCW-3 oils are the same.

Considering what outboards cost, why take the chance? If the manufacturer says uses a certain brand and that brand is a little more expensive, so what? Cheaper than replacing a powerhead down the line.

[Wayne P.]

Way2slow, have you read the Magnuson-Moss Warranty Act? Do you know of any motor mfg that "requires" the use of their brand oils for maintaining the warranty? (Name one) Do you know of any motor mfg. that has denied a warranty claim based on oil brand?

From the Mercury Service and Warranty website: http://www.mercurymarine.com/serviceandwarranty/outboardfaqs/fuel.php#8

Some non-motor brand outboard oils are more expensive than motor brand oils with the same qualities. Does that make them better?

[mattm]

I've been using Quicksilver for about a year and have had no issues.

My merc manual says to use mercury oil or twc-3 any use of anything else will void your warranty.  Or something like that.  I can get Quiksilver right down the steet at Napa so thats what I use.

[Way2slow]

Not getting into any p***ing contest about oils, warrenties, who runs what, and how many years someone has run their favorite cheap brand. Like I said, I could 100% absolutely care less if someone wants to run no oil at all. I've always said, no one is going to tell me how I should operate my equipment and I for dang sure ain't gonna try and tell someone else how they should operate their's.

I just happen to have enough personal experience with outboards and oils to know what I would run and what I would not waste my money on.

By the way, Quicksilver is a very good oil and is all I ran in the Merc's I raced back in the late 60's/early 70's. I have an old 88 Merc 115 "Tower of Power" that's on a boat at the lake. Quicksilver is all that's ever been run in it since it was new and it's still a very sound motor.

Just be sure you understand, if you have DFI motor, or any motor with oil injection, the manufactor calibrates the oil injection for their recommended oil for that motor.  The Viscosity in different bands/grades of oil can vary and can even change more at different temps.   Running anything other than the recommended oil in these motors can cause under/over oiling of the motor.

Topic:

Quick Silver and Merc are one in the same!

Are all oils the same, no. Go to Amsoil website and check out their independent studies.

Does anyone here use Amsoil or Royal Purple?

[Wayne P.]

I used Amsoil HP Injector when I had a 2-stroke 150HP. Some may not want to use it in a new in-warranty engine since it is not NMMA or BIA certified. It may be the best 2-stroke synthetic oil marketed and it is "recommended" by them for TCW III applications, but it is still not certified.

Looks like Citgo makes mercury's oil. See last page.

Do you think they make it different than the stuff they make and sell under their own name?

http://www.docs.citgo.com/msds_pi/621602001.pdf

Looks the same to me.

Yamaha is made by Citgo as well.

http://home.comcast.net/~team_dougherty/results/yamahamsds.pdf

Is that different as well?

I really do not think citgo makes different oil for each. They just put the same stuff in different bottles.

I also think Yamaha, Mercury, OMC and other put their oil out to bid every year and who ever can sell it to them the cheapest get the contract. One year it is Citgo the next Texaco and maybe Chevron the year after that.

[Way2slow]

Yep, just like Goodyear uses the same compound to make all their tires and the tires they make under other brand names, they just base their price on the different tread patterns and names they put on them.

That makes about as much sinse as saying all gasolines are the same, after all, almost all gasoline sold in an area comes out of the same pipeline, so why buy a name brand over the discount, no-name stuff.  I'm sure the no-name stuff gets the same additives the name brand stuff gets.  All that build up on the back of your valves caused by the no-name must have come out of the engine.

[Team_Dougherty]

comparing Tires to 2 cycle oil is like comparing apples to oranges.
