Full synthetic tcw 3 oil

[boater1234]

Many,many,many people swear by the amsoil 100:1 in any 50:1 -100:1 outboards. There must be something to it. I think we all know any oil today is much better than the past and the chance of a engine having failure from certain engine oil is near nill,it's not very common. Most engines break down due to owner neglect not certain oils but I do believe synthetic does protect better than conventional oil. The only reason omc went back to the 50:1 was the engines that sat for long periods of time had the problem of corrosion in them so they switched back from 100:1 to 50:1 and for no other reason that I can find so far from research. That tells u if you constantly use your outboard on a constant basis 75-100:1 can be used with no issues . There is nothing I can find that states 75 to 100:1 won't be enough oil to lubricate an engine except for people on forums. I myself run around 60- 70:1 because I find it just right for smoke reduction and my engine seems to run really smooth that way,much better than 50:1. I basically use a couple to few ounces less oil and it seems to make a huge difference on how my engine runs. I also use full synthetic oil if that makes any difference.

All these oil threads get boring after awhile. Who cares what's best and what does "BEST" mean anyway? As evidenced by the testimonies here, ANY oil will work and work just fine. Nothing will make the motor suffer. Personally, all I care about is smoke, or lack there of.

In my youth after Grandpa gave me his Mark 10 Merc, I simply used 10W30. Why? Because it was 32 cents a quart. Formulated OB oil or TCWwhatever....pfffft. You know, I don't even remember if it smoked or not, but the motor is still running to this day.

Of course, I'm an old codger now and can well afford the TCW stuff. But, I find no need to experiment with XRD, 125% synthetic or whatever. If it don't smoke I'm happy. Whatever it is, I'm sure the old 'Rude will outlive me.

How old do you have to be to be considered a codger?

 

[JimS123]

How old do you have to be to be considered a codger?

Old enough to remember:
* when oil was oil not TCWsomething
* when you envied the guy with the 75HP OB because he was the fastest on the water
* when the smartest guy on the water was your Grandpa
* when fiberglas was considered cheap because it would rot before your wooden boat
* when your companion in the boat was a cute girlie, not your wife (the grandma)
* when you couldn't go boating as much as you liked because you had an affliction (called a "job"....ugggghhhh)
* when you learned from books, the old codger at the marina, or from personal experience (before internet)

I ran the Amsoil in my 2000 175 ficht and the smell and smoking was almost nil. very good product! as for 100:1 I would start ar 50:1 and gradually lean it out to as Rich a mixture as you can get without the smoke and smell. I think you can get away with 75:1 with amsoil...but I also think that even at 50;1 the smoke and smell will virtually disappear.

 

[boater1234]

Well,I'm running at near 60-70:1 as of now and the smoke has nearly dissappeared. The engine runs so much smoother at this mix then 50:1,I mean an incredible difference. I can't see how any mix of any synthetic oil up to say 75:1 would hurt any outboard. We have been programmed to run 50:1 because that's all u hear but again it's been proven a bit leaner mixture,nothing crazy but like say up to 75:1 seems to work with great results in all outboards. There are so many people running at 75:1 in all 50:1 outboards with fantastic results, near no smoke,smooth operations and no plug fouling. Like I said I tried this last batch at 60:1 and just that few oz of oil made a huge difference in running imo. I run 12.8 oz of oil per 6 gallons and I get a perfect 10 fill ups out of a gallon so I'm sticking to that. That is 60:1,just a hair leaner.

How long did you keep your Ficht?

There are so many people running at 75:1 in all 50:1 outboards with fantastic results, near no smoke,smooth operations and no plug fouling.

That ratio should work fine for idle/fast idle operation, plane while at 1/2-3/4 throttle, how about when full wot revs are in demand for extended time periods, have you tried running 75:1 under harsh boating conditions.

Wouldn't like screwing my nice OB's just to save a few bucks worth of oil.

Happy Boating

 

[JimS123]

I run my Yamaha 2-stroke at 100:1. Why? Because that's what the manufacturer specifies. It smokes with crappy oil (like Pennzoil), but runs fine with the good stuff. My plugs look perfect. I have only 250 hours on her now, so time will tell I guess.

 

[boater1234]

My point is a yamaha,merc,suzuki,johnson,etc can all run on the same ratio of say 75:1 if someone wanted to and their is nothing to support that it can't, like actual proven engine disasters from that ratio,there is no difference in how those 25hp 2 strokes were built that I know of unless I'm missing something. There are many people who have ran even 100:1 for many yrs,10 or more with no ill effects so there must be something to it. Oil is oil I agree. Many ,many people run pennzoil with no issues . I heard way back in the day it had a bad rap but any oil today is good quality. I just am extremely curious what makes amsoil 100:1 so good,that was my main question,I'm very curious what separates it from the rest? I will continue to run my own outboard at 60:1 because that is what seems to run good in it and it works out perfectly per gallon of 10 full tanks,plus I get near no smoke now surprisingly. I'm just saying we been programmed to do certain things for many yrs and oil is much better now then back in the day. 50:1 is just the staple for almost all 2 stroke outboards except yamaha,but that doesn't mean another ratio won't work.

Amsoil 100-1 is a pre-mix oil only so it's formulation is different. Regular injector amsoil has to be mixed 50-1 to run.
Injector oil is different because you cannot change what the injection system does it injects a preset amount of oil so the additives are different. The premix since it is mixed in gas and is going to be used at a leaner ratio has to have different lubricity additives and has to resist being broken down by fuel. I have run amsoil 100-1 succesfully in my 70 hp evinrudes and 75 hp mcculloch they stand behind their oil with a warranty. The oil you use is the key to the ratio you can run. That being said where are all these people you say are running these lean oil ratios I would like to hear from them. And as far as your motor smoking less on 60-1 that sounds like you have set-up issues. I have 2-25 hp mercs 1987/88 models neither of them run rough or smoke with a 50-1 mix in them. You sit here and want to convince everyone they can run lean ratios in their motors but yet you are only at 60-1. Why don't you run your motor 100-1 and tell us how it goes don't make everybody else your test mule.

 

[boater1234]

Test mule,your funny. Obviously you don't read very well. All I asked was what makes amsoil different. You said it yourself so your contradicting your own words,you said you have run 100:1 with no issues so that makes u the test mule already.Read forums,I have read hundreds to thousands of different forums were people use 75:1/80:1 and 100:1 with great results using synthetics only. I have read many Older threads here that states 100:1 saber can safely be run in any 50:1 engine. It's all over you tube with people running engines on the 100:1 amsoil so what do u mean. Can you show me one shred of evidence that a leaner ratio can't be run,absolutely not,but you have yourself as many others have run a much leaner mix at 100:1 and been successful as you say,what does that say,it can be done with no issues. Also I said most could be run at 75:1 if they chose to,not 100:1. I can prove to you that a motor can be run on a 100:1 mix safely when it supposed to be run at 50:1,your evinrude out of your own mouth. You say run what the motor calls for like my merc,your evinrude is supposed to be 50:1 but you ran 100:1,what does that tell you,it can be done with no ill issues. I just showed you it can be done with your own words.

 

[Sea Rider]

Independently of the fuel/oil ratio you want to run on your 2 strokes OB, will be interesting to see the internal degree of wear each OB will achieve, say 3 using 50:1/75:1/100:1 at 1500 worked hours for same type of work.

Will remain at 50:1 while using Amalie dino oil, that's what Tohatsu calls for. BTY, don't see a single new 2 strokes pre mix models Yams being labeled at 100:1 all are 50:1.

Happy Boating

 

[flyingscott]

You missed the point completely. The engines themselves are not designed for a certain ratio they only need to be lubed. I will use my McCulloch as an example since they were the first with 100-1 factory mix and were successful at it. In the owners manual it states as long as I used McCulloch oil I could run 100-1 anything else had to be 40-1. If you look at the Amsoil package it states if you use the engine for heavy use such as tubing/skiing or commercial or racing uses you have to drop the mixture to 50-1 or 75-1. So this advantage you are looking for by leaning the mix out isn't always there. There was a negligible reduction in smoke on my evinrude still smoked when it started up. There was no running difference I did not pick up the 100-200 rpm they claimed I only ran it for a while because I could only run the 100-1 at certain times. On your motor the main weakness is the center bearing on the crank I have seen enough of those fail that I wouldn't run anything but 50-1 in those motors. The difference between 50-1 and 60-1 is negligible so the running difference on your motor is probably more perceived than anything. So go run 100-1 in your motor for a year and come back and tell us the results when you have some real world experience with these mixes. Don't say youtube videos and google for your fact finding. By the way all my motors run 50-1 now.

Just like the program mash was on longer than the actual Korean war these oil wars are longer than any war with maybe the exception of the 100 years war. I'm just as guilty as anybody ,lol.

 

[boater1234]

Again,I said I don't personally run 100:1,I run 60:1 and I'm sticking to that due to the way it works out per gallon for me,10 full tanks. My engine runs as smooth as silk now,it runs like a rapped ape with little smoke and I'm happy. I use royal purple oil and pennzoil all full synthetic and I love both oils but I may give the xd100 a shot because it's local and available and cheaper than both oils I use now. My motor was just over oiled due to my error,now it runs as it should.

 

[82rude]

Just check with the dealer and make sure xd100 is ok for premix.I mistakenly bought a gallon of evinrude oil at wallyworld and found out its not for injected motors so the same may apply the other way.I now have a 6 hp Johnson 2 stroke kicker so the oil wont go waste .

 

[JimS123]

BTY, don't see a single new 2 strokes pre mix models Yams being labeled at 100:1 all are 50:1.

Happy Boating

My Yami 25 is a model year 2009 and it specifies 100:1. I tried to buy another one for my son in 2010 but the 2 strokes were not available any more in the USA. Thus, my guess is that you can't find a newer one unless you go overseas. Are you saying that the "new" 2-stoke Yamis overseas are 50:1?

 

[82rude]

I looked up Yamaha Australia and looked at reviews of the 2 stroke premix cv30.(30hp)The fellas reviewing said 100 to 1 was factory recc.

 

[boater1234]

All yamaha pre mix engines are 100:1 and have been for a long time,but many don't trust the 100:1 oil ratio and decide to run 50:1,yes going against the manufacturer . My feeling is if a yamaha can go on a 100:1 mix then any 25hp 2 stroke should be able to,unless all the other 25s are built different, use different internals?????. It's like breaking in a new engine ,the manual u get with any 2 or 4 stroke outboard says to break in each engine exactly the same,how is that possible when a 2 stroke and 4 stroke are 2 totally different animals but have the same break in,a 4 strokes rings are much harder to seat then the 2 stroke from all I've read, that is a whole diffferent thread but the same concept, we're programmed to break in all engines the same just like we're programmed to run nothing but 50:1 in every pre mix engine.
