I bought a 2.5 gallon container of Exxon 2 cycle outboard engine oil at West Marine today. The price was $22.99.

The same sized container of Mercury-Quicksilver oil was approximately $33-34.

Any opinions on whether the overpriced stuff is better for my 90 HP 2 cycle Mercury?

Opinion? Yes: If it is rated TC-W3 it is good enough.

Thanks JB

Yes, it is rated TC-W3.

There is also a note on the container stating that the owner is not required to use the OEM's brand of oil for warranty purposes.

What about Walmart branded oil for $6/gallon?

I have known many who choose to use the Walmart branded oil, including a perfectionist who used it exclusively on his snowmobiles which are far more demanding on the qualities of the oil than mere outboards. I have yet to hear of a problem with it. My only concern would be to pick a brand and use it consistantly, not play mix and match with several different brands. This is because some are truly petroleum based, some are synthetic and some seem to be somewhere in between. This is a potential problem especially if you are using it in cold weather.

BUY THE GOOD STUFF!
GAwhale How much did you pay for your outboard?
Different oils have different additives. Additives reduce carbon build up which can cause stuck rings and heat build of pistons.
TWC-III oils allow 12 % scuffing, Merc oils allow zero.

I also have a Merc 90 hp 2 stroke.If you buy 6 gals of oil a year at 50 to 1 ratio that good for 300 gallons of gas. That a lot of gas for a 90 hp motor. On sale at Basspro you can get Mercury brand oil for $10.99/gal. Walmart brand at $6.99 gal. Thats $4 per gal difference times 6 is $24 dollars annnual increase in oil cost. For $24 this gives a piece of mind.

I am not confident that Walmart's as good as Merc oil,but I am confident that merc is at least as good as Walmart's
Ask this question to yourself. If they were the same price which would you choose? I think that 99% of us would choose the Mercury brand for the Mercury engine.

Merc hypes it's oil as a wonderdrug. It isn't. It is good oil, Pennzoil is good oil, etc., etc.

WalMart Super Tech is Pennzoil in a different bottle (Read the label). When you buy SuperTech, you aren't buying all the snake-oil marketing you have to pay for when you buy Quicksilver.

The implication that if it isn't Merc, it allows 12% scuffing is typical "Merc"eting nonsense.

I was buying the cheap stuff (Exxon or whatever West had on sale) until I saw this topic on a thread here about a year ago. Since then, I've been buying Quicksilver. Why? I have an old but solid Johnson V4, a motor know to fail from carbon build-up. I figure a few bucks more per year on oil is cheap insurance. I also use OMC carbon guard additive for the same reason.

How does the Johnson/Evinrude branded oils rate?

I just wonder-In all reality, How many makers of 2 stroke oil are there? The packaging/marketing may differ but only a few folks are really making the stuff. It's like engine parts for autos. My .03. David

if you go to certain dealers with your own jug, $10/gal for either OMC, Quicksilver, Yamalube, or Zuki. I use OMC because it is convenient. I personally think all premium oils(mentioned above) are identical. I personally will not use Citgo or exxon, etc for a lousy $3-4/gal savings. For even $100 a season in added oil(a lot of oil), it is worth the peace of mind. Do what you want but $4 a gal is worth it in my eyes. You buy oil at West, Boaters world, etc, you should shop elsewhere. Try Sam's or Wally world and buy bulk if no local joint sells by the gal.

David R, you have a valid point to a degree.

The engine manufactures don't refine their own oil. However, what they do is specify the additive package for their engines. This usually is accomplished through coordination of research/testing with the oil companies research engineers and the outboard company engineers.

I do know first hand the folks which produce "oils" for various OEM brands including autos test engines extensively to determine the proper formulations. That's no BS! There are differences.

Here is a link to an article which is in part taken from a Penzoil FAQ which represents a number of points one should realize about oils --- as is stated by the fellow who put it together whether Penzoil is really the best well you can decide --- the information is applicable to all 2 cycle oils --- http://www.ultralighthomepage.com/OIL/oil.html

bigZ you seem to have a point about additives. Then my question is--Is there empirical data showing the value of this or that additive. It seems that the TCW3 additive is the key one,since, we know it has improved outboard performance. The old stuff use to gunk up carbs rather quickly. What do you know about Texaco 2 stroke oil sold thru Boat US? Should I move away from using it in my 225 Johnson? Thanks David
bigz posted 11-26-2001 01:33 PM ET (US)     Profile for bigz    
David don't know a thing about Texaco brand oil other than it meets or exceeds the TWC-III specifications which is the same statement made by most oil branded or not these days.

My point was that with folks like Yamaha, now Bombardier E&J, Mercury, etc. the OEM branded oil these engine manufactures test and refine additive packages that they feel best suit their engines performance characteristics. In other words if Yamaha finds their engines have a tendency to do xxx then they formulate to reduce xxx on the other hand Mercury finds there's does xxx+2 they in turn work on an additive to reduce xxx+2 or for that matter increase it --- think you get the idea.

I ran Exxon in our Yamaha 200's with very good results. As a comparison I was forced to switch to Chevron --- we had more smoke and a carbon build up after we used a case than anytime before with the Exxon. In fact had to decarb the engines after that case -- needless to say we went back to Exxon.

Currently to play it safe we are using Ficht blend with carbon guard in the 225 Ficht engines. I get it in bulk for $11 a gallon.

As you might tell I am not going to debate OEM vs. Major Brands vs. Store Brands, if they meet the specs then your warranty is valid --- regardless what brand you use it is always beneficial at least annually to decarb the engine ---

As an aside --- in the industry Mobile is known for the best synthetic and Exxon for the best "natural" lubricants, I suspect this is because of the tremendous amount of research each does compared to the others --- sure this could be debated --- (there are a number of small lubricant packagers that have nitch markets which probably for specific needs offer good stuff)

Now for a sales pitch --- ;)

Anyone need some Exxon Oil 2 cycle -- (I know it isn't "market place") --- special garage sale --- I have 12 gallons @ $6 per gallon (should be in or close to NJ don't want to ship it)--- used it in the Yamaha twins on the 27 ccc, it is a fine oil as mentioned above --- Tom

PS take all 12 gallons you can have it at $5 per gallon ---

Thanks- I get the drift. This is my first experience with outboards so your insights are going to be put to use. David

One point to add to this discussion...
"It will meet the warranty requirements." At first this seems to be a valid reason, but I have never met anyone who wore out his/her motor within the warranty period. As owners of classic whalers, we are all intending to keep our rigs for many years. Just allowing the motor to survive one (1) to two (2) years to fulfill warranty requirements is not enough IMHO (yes, I know some warranties are longer). I suggest you use only Mobil (4-cycle), Exxon or your engine manufacture brand. In an earlier thread we all talked about our hours per season, most were well under 100 hours. This number of hours amount to not much gas and oil per year. Buy the best, our whaler deserve it.

I use whatever tcw-3 oil I get. Right now it is westmarine's exon oil I believe. The store is in a convenient location. I think the most important thing is the tcw-3 rating. I run an additive to reduce carbon buildup I figure it does more than the additives in the oils. Keep in mind my motor is 14 yrs old and I use it alot! That equates to alot of cheap oil and let me tell you at anyprice it adds up quickly. When I get a new engine I will probably be more consistent with the brand of oil I use unless I get a 4 stroke.
