Another amsoil 100:1 question,Lubedude?

[carbineone]

I have done some reading here regarding the amsoil 100:1 controversey but my question is differant.I bought a old Aquascooter for my kid to paly with next year and if you are unfamiliar with what they are I will include a pic and some info.They are a 2 stroke powered,submersible to snorkel depth water scooter..My question is concerning the oil mix.

It is supposed to run 50:1 originally but the problem is they are running submerged in the water so they run very cool of course and that can cause problems with a cool running motor getting carbon buildup,plug fouling and such.If you know anything about this oil let me know your opinions if the saber synthetic outboard would be a good choice for the scooter knowing it will be running super cool under the water.I think LubeDude is a amsoil dealer,if your still here let me know your input...Thanks

Anyone?

Ok, I'll bite.
Run any full synthetic at 50:1 and you'll be better off than conventional at 50:1. Unless you're the motor designer, you'll really have no idea what 100:1 will do to that motor.

Why not run what the manufacturer recommends? Do you think you can guess at something better, or take someone's advice over those who designed the machine?

Personally, I'd never recommend that anyone do anything in conflict with the mfg.s recommendations. If they say go 50:1, I'd never tell anyone to go 100:1. That's way outside of my comfort zone.

Re: Another amsoil 100:1 question,Lubedude?

The analogy for the non-mechanical than many can grasp I like to use when addressing the whole 100:1 discussion is "tire pressure". Take your average auto tire designed to be run @32-35psi. Now that tire can and often is run @ 40, 45 or even 60psi. There are trade offs when doing this and going outside the oem's reccomended pressure. I wont go into those, but many have enough of a "tire" understanding to grasp that.

One thing many do not understand especially when dealing with older carbed engines, is that altering the oil ratio changes the jetting.

Yet 40 years ago I owned a 9 hp McCulloch OB that was clearly designed for the conventional 50:1 mix ratio but McCullloch was selling both a 50:1 mix oil (blue) and an optional 100:1 mix oil (red) and I can remember the dealer telling me that it did not matter which one I would use to comply with the waranty of the OB. Nowadays I read different because it's called Amsoil Saber .... go tell.

Re: Another amsoil 100:1 question,Lubedude?

Well after researching the net for several hours it appears that what the manufacturer reccomends in these early aquascooters and the currently manufactured ones is the Amsoil Outboard mixed at 1.5 ounces per gallon.I do not what that converts to though as far as ratio.The reason they claim to use the amsoil outboard specifically is that these engines run extremely cool of course being submerged in the water.Hence the higher ratio I suppose for the cool running motor.These actually run totally submerged so in 80 degree water they are running extremely cool I would guess. On amsoils website they say the oil is for cool running motors and prevents carbon buildup,plug fouling and such.Makes sense to me and it appears it is the way the manufacturer now suggests even though originally when built they reccomended 50:1..I know this may not be of much good to anyone else as they more likely do not own one of these but you never know.What would 1.5 onces to a gallon come out to as far as ratio..I flunked 2nd grade math....Thanks

Re: Another amsoil 100:1 question,Lubedude?

Seems like either 75 or 80:1 ratio. Only the Amsoil "Saber" oil has such high ratio recommendation by that company.

Re: Another amsoil 100:1 question,Lubedude?

100:1 is 1.28 oz./gallon. 1.5 Oz. is 85:1.

Re: Another amsoil 100:1 question,Lubedude?

I'm not a chemist or an engineer . and I can remember back in the good old days when chainsaws used a good old 30 weight engine oil mixed at 25 : 1 . Later 50:1 2-cycle mix arrived on the scene .There was a period when 100 :1 mix first came out that saws were blowing up regularly so they went back to the 50:1 mix. My question is (1) Is the new 100:1 lubricating properly ? (2) Is the oil burning off correctly ? Or over loading the crank case ? Sure it may run, but for how long ? I have a husky that was built in 1958 I use it for log building and firewood , lots of hrs. on it and it is still going strong. Just did my maintenance and put in the odd carb kit.

Re: Another amsoil 100:1 question,Lubedude?

The manufacturer endorsements indicate a fairly low piston speed. I would suspect this engine is in a very mild state of tune as far as 2-stroke engines go. Who makes the engine...bore/stroke?, working rpm?

Re: Another amsoil 100:1 question,Lubedude?

I once worked for a beauty product manufacturer, and have seen how they can make 250 galons or water becoming 250 galons of expensive shampoo by simply mixing in approximatly 1 pint of mixed chemistry products ... at the right time and the right water temperature ...

Leads me to beleve that Amsoil and McCulloch new what they were doing when they came out with 100:1 lean mix type oil to be used where 50:1 is mfg specified. As per my OB mecanic these oil companies have their own manufacturing chemistry secrets ... and wont tell us.

But then just like you I am not a chemist nor an engineer.

Re: Another amsoil 100:1 question,Lubedude?

While this is slightly off topic...I have performed many controlled test with high performance two-stroke engines. From a purely performance standpoint 100:1 will never out perform 50:1 or even equal it. The 100:1 ratios are not designed for performance. They were designed for the need to reduce the emissions surrounding the typical 2-cycle engines use.

Re: Another amsoil 100:1 question,Lubedude?

Man do I feel dumb or am I? I have been told and believed my entire life (57) the only difference between a 32:1, 40:1, 50:1, etc is the amount of oil/fuel ratio. They make those sexy little bottles that say 32:1, 40:1, 50:1, etc. as a convenience to mix with a particular volume of fuel and they can charge more. You can buy the quart and mix it accordingly if you want and save a ton of money just buy for the application not necessarily brand of engine. Now the one mix for all like Amsoil Sabre and Opti-2 is a different animal. I have used them for several years in all my two-cycle equipment and I have some old stuff still running strong. I have 1 tank of gas for everything. I have talked extensively with two different dealers and they both recommended their use and said there would be no warranty issues with using them. I wasn't using them in new equipment so I didn't have to test that? Both dealers said that they usually see more issues with too much oil as opposed to too little oil unless they've done something stupid. For all you naysayers read the link below and go to the 2nd post down, might shed a little light.

Hummmm odd thread ... not an oil war ... an people in favor of mixing at 100:1 with Amsoil Saber &/or Opti2 ... am I awake ? LOL

Maybe it's mowing your lawn and not boating that's relaxing and takes the stress out of your daily life.

Re: Another amsoil 100:1 question,Lubedude?

I do not know the bore or stroke but the little engine in the scooter is made in Italy in 1982.It is a 50cc displacement and is rated at two HP.They make a attatchment for it that you can hook it up behind a small boat and use it as a little tiller 2hp tiller motor too.They are supposed to pull a person through the surface and and under the water at a couple foot to snorkel depth at app. 5MPH.I think my kid will have fun with it..You mentioned emmissions too.That is one good thing they say that the amsoil is good for too,it says it produces less odor and smoke and such so that may be important to when using this right in front of you,although it exhausts under water from the bottom of the unit...Thanks

Interesting.

I am on the fense between abandoning the oiling system on my early-mid 90's 2.5L 200HP Merc, versus keeping it.

One idea that just entered my mind is to mix Amsoil Sabre 100:1 (figuring it's not TOO much oil combined) AND keep the oil injection system using standard oil. Crazy... but paranoid.
