100:1 Mix

I had Opti here and cross examined it against another oil that was for 50 to 1. I live at a very high elevation. So having to re-jet carbs is of course a given no matter what. I compared to my 50 to one oil and guess what.......... the Opti was very unmistakably thicker . This just means it is thicker oil. ''The oil is clearly thicker in viscosity''

Every body is still mixing oil the same way lol.:p:D:-{laff


100 to one 50 to one 30 to one. Ah smellgha Water down some bearing grease . ''Just Kidding''
 
I got the same engine I was running before that was posted here at well over 10,000 miles on it flat out beet to death running over well over 10,000 rpms whole days at a time.. Can see factory cross hatch marks still on the entire cylinder wall surface area. I ran Amsoil on it for the most part. Have fun run it hard play hard. Life is sure sweet to us!


I have dabbled with the Opti and from what I can tell it is good stuff.

Let us know how much "slap" you have coming from your bottom end after 100 miles! The oil in the gas is to lubricate your crankshaft bearings, piston rod and piston.
 
I've been using Opti @ 100:1 for break in and thereafter on my engines for a long time. Never had any issues with rings not seating. Never had a catastrophic failure, or any other engine issues. But that's just me.

Oil preference is like most other things. You need to do what works for you and let others do the same.

Whoa!!!! Something bad is happening :(
Went for a ride this morning with the oldest bike, the Chris Hill 80 with over 1000 miles on it. It has always run like a clock and did the night before I switched oils. The first two or three miles it ran okay, nothing noticable different until today. After less than a mile I began to see a rather dramitic decrease in power. I turned around and headed for home at a blistering 12mph. And that was all she would do, had to pedal up two hills that I normally take at 20, easy. It doesn't idle and is slow to respond to throttle. After finally getting home I've looked at everything. Muffler is clear, good compression, good spark, fuel bowl, line and carb are clean. Good fuel flow. The plug looked good but I replaced it anyway. There wasn't much carbon on the top of the piston and it looks like it did before the oil change. So what's different? 24 hours before the engine was running great. Now with the Opti-2 it won't get out of its own way.
I'm going out now and mix up a batch of my old 2-cycle oil and fresh gas and draining the tank. That's all that's left to try. I'll come back with the results later.
Oh, I have not even started the other bikes after the initial 2 miles or so that I tried yesterday. I don't want to take a chance that I'll screw something up on all my engines.
I'm tempted to ride one and see what happens but I'm going back to the old mix on the CH-80 first, just to satisfy my curiosity. I'll be bock............

So was the issue with the carb?

He already explained the reason, old already mixed gas was mixed with the opti2.

No, 2doors first posts in this thread (first 10 pages) are about his switch to opti-2 and all the trouble he had. He even had flushed his tank before switching to opti-2
 
That was a long long time ago. I still have that old bike although its hanging from the garage ceiling and hasn't run for years. The engine was a Chris Hill engine and was broken in on standard 2 stroke oil and ran fine but it did not like Opti-2. We never came up with a conclusive answer as to why. It runs fine on, or did the last time the engine was started, on regular dino 2 stroke oil and I never tried Opti in it again.

Since that engine every other one I've had was broken in and run exclusively on Opti-2 at the recommended 100:1 ratio. Never had one that gave me any problems except that original Chris Hill engine.

Maybe someday when I'm bored I'll get that old bike down and see how it runs. It was never the powerhouse that later engines were but it had a lot of miles on it. It was my first build and I've kept it for the sentimental value. If/when I run it again I'll report if I experiment with running Opti in it.

Thanks for clearing that up

I've been running Echo powerblend at 24-32:1 and was thinking about testing it at 50:1

If it runs significantly better I am thinking about moving on up to Opti2
 
Just bumping this very old thread because of a screwup I made recently. I have a new bike, new engine and as I've been doing for a long time, breaking in the engine on Opti-2 @100:1. "Sumpins not right" I told myself after the first few miles. Lots of oil residue from the pipe and not near the power I was expecting. Here's what I found.

I had a gallon of fuel for my snow blower but forgot that I'd already added the oil. So, I added the oil. Now instead of 100:1, I had a 50:1 mix and that was what I dumped into the bike tank. It was nasty. Smoky, stinky and an oil fouled plug.
OK, it was double the recommended dose of Opti2, was just going on memory, a bad memory.
Still it was an oil related issue and it was for his snowblower, I remembered that much.

I use that at 50:1, next to Opti2, In my opinion is the next best stuff you can get.
Very highly rated oil, rated amongst the best.

ECHO Power Blend Oil exceeds ISO-LEGD and JASO M345/FD requirements.

Make sure your oil manufacturer recommends a 50:1 mix. Reducing oil content/ratio is okay as long as the oil is meant to be used that way. I say this because of a question I remember being posted some time ago by a new builder who asked if he could run Wally World 2 stroke oil at 100:1. I wouldn't want to try that. :)

Thanks for that info. I had put off that little experiment fearing my 2 smoke would go boom between by legs

Yeah, it's rated for 50:1.

But I figured I'd be cautious as I was breaking in the engine

I think she's broke in by now
 
I am Tired of all this nonsense! Everybody's experience are e valid. No argument.

BUT! Everybody has HEARD of AMSOIL. Their polymer based lubricants are labeled for TURBO JET Engines, they have my respect.

Amsoil's 2-stroke lubricant, SABRE, is without peer. At $11.00 a quart, at 100:1 will last a year before new refill is needed.

Last time I posted on this forum My bike was just broke in. That was moren' a year ago. Then I started Sabre at 100:1 and the bike has been powerful, QUIET, and functional without defect day after day. Muffler shows no need for replacement,no smoke, the bike is dependable daily transportation.

Doan buy no steenking 4 oz. bottles of Sabre at $5.00 a bottle. Buy the quart!
