100:1 Mix

Hmm.
I've kept up with this thread from day one when John (the retired machinist, whatever happened to him?) first posted his findings. I've read the pros and cons and as all of you know I'm a die-hard Opti-2 user. That's in contradiction to the warnings from engine suppliers and those who have never tried the stuff.

Initially the thread was interesting and informative. However, it seems to be going the way of many threads and turning into a platform for argument.

I submit that any future posts to this thread be only first person findings and experience using a 100:1 mix, Opti-2 or any other blend, either positive or negative. I believe it goes without saying that the majority of those running this so called unorthadox lubrication ratio have found nothing to sway their devotion to it from the naysayers and backyard 'experts'. By the way, you don't get conclusive test results by bolting an engine to a stationary mount and running the heck out of it. A no load test, even if you throw on a propeller, doesn't duplicate real running conditions. Engine designers, when testing their designs either put them in vehicles and drive them or they are set up on a load test dynometer which can impose real world conditions.

This said, I stand by my submittal that this thread should, from this day on, reflect only positive or negative results USING the 100:1 mix ratio. Let's stop the bickering. It's repetitive and non-productive.

But, I am interested in this ear wax idea.

I've heard alot about this 100:1 oil where can I get it ? I'll admit I haven't read all 89 pages but I'd like to try it in my new engines that have never been run before,let me know and sorry for not reading all the pages, 89 is like reading a novel.
 
If you have an ace or a true value try there, if not napa sometimes will sell something called sten mix which is re-packaged opti-2. The most important thing to understand about opti-2 is how it behave in a 2 stroke engine differently than other oils. There is an additive (I believe it is boron based) that smooths surfaces in the engine to a microscopic finish. When compared to factory fresh cylinders, and cylinders run on conventional 2 smoke oil, the opti-2 is the smoothest by far. I have run it in all of my 2 strokes including my chinagirls and I can say for certain that everything that has gone wrong on my engines so far has been due to vibration and poor construction but NEVER oil failure. If you use opti 2 you WILL like it!
 
WoW !

90 pages!!!

I kinda think if an engine were built so it was not feeding it's own construction QC flaws through itself, (slag and mismatched gaskets), and an effective intake filter was used, the only thing to create premature wear in the combustion chamber would be build-up of ash from combustion.
We gotta use the petrol, so it might follow that less oil, provided it accomplished the lubrication needed, would be better.

The glowing testimonials have convinced me!
When I burn through all the various jugs of 2 smoke mix oil I've got around here, I'll run one of the 100:1 flavors.

Buy local!

I was tempted to buy online, but shipping is killer!

I'm glad I found a local distributor. Small packets were very expensive. The larger the container, the cheaper per oz. I walked out with a 4-liter container. With tax, that cost me $90, which is less than 67 cents/ounce. That compares to 52.5 cents/2 ounce that I'm using.
 
Check your local tool rental places. Most of them sell products along with their rental business. I buy my Opti-2 from a rental place and...they use it in all of their rental equipment, 2 and 4 cycle. Yes, there's an Opti-4 for you four stroke fans.

You can also call Opti. They'll tell you the closest dealer to you.

I don't think so Biknut, I trust it in chinagirls because they're easy to replace and I know the chinas like them, but I'm gonna use motocross oil when I get myself a morini...
 
Well I just got my bike running again and this time its on Opti-2. I made a 70:1 mix of it, and it runs nicely although very rich, which was expected. I'm going to do some fine tuning on my bike after the fresh 100% rebuild of everything anf hopefully by mid winter it will be complete. First things first, get a new jet for my RT carb.
 
found this stuff today at runnings called US2 2 cycle engine lubricant. comes in a pouch seams to be just like opti-2 just wondering if its the same kinda stuff?
 
Read the fine print on the pack, if it's from interlube it's probably a rebranded pack of opti
 
US2 and Interlube, makers of Opti2, are not the same company.

US Motor Power is the mother company to US2 Oil.

US Motor Power and Interlube are not the same company.

Interlube packages Opti2 as US2 for US2 Oil.
 
i am running an oil called quick silver its a nice blue colour im still on break in at about 150 miles i am mixing 6 ounces to a gallon and soon will mix at 32:1 but i have had the bike up to 36 on level ground think it will do 40 after break in new plug and new mix if so ill get a smaller back gear and see if i can go 30 all day with less rpm
 
I'm not an expert. Based off the thread and my experience with weed wackers and what not (Breaking in some)

My friend was always like woah dude too much oil (I taught him how to work mower and such, premix) He read the book but didn't listen to the break-in part, and it said raise till no oil spitting out or max like 32:1 or 40:1 on one of them.

I'd run a small mixture of seafoam switching to this new oil.

for the 100:1 mix, take it easy going up there, first focus on not having oil deposits. Once you're above like 40-50:1 take it slow & easy.

Lastly with the Opti2 I'd do like seafoam as said, but I would run it hot, then take it easy 3/4th throttle or so max.
 
I have a 2 stroke Maruyama weedeater engine that I am considering mounting on my bike. I run it with a 100:1 mix with Amsoil 2 stroke oil Saber Professional. Then I just read that the Amsoil has been tested at an amazing 300:1 mix, so I ran it at 200:1 and it ran great! Although Amsoil has been tested at 300:1, they recommend 100:1 because no one would believe 300:1
