Opti 2 Oil

[Dwight Rudder]

I like Maxima Super M at 40:1 .  Super clean and lubes well.
I will admit to using what I think is Optimol. I was using a private labeled 2 stroke Aviation oil called Blue Max Av oil. The oil looked like Opti and the label read like a Optimol label.  They recommended 100:1.   I recently sold my Aeroplane and had a case of the Blue Max oil left.  I have been using it at 80:1 with good results.  Sometimes at 70:1 ?  10oz to 5 gal.
Seems to work OK.

............while setting many national drag race records and winning some nationals,pro roadracing/regional championship  days as well as my days as a factory Sno-Jet driver/R&D guy we found out the hard way, any engine that will run on 100:1 will run on straight gas,all this hocus pocus alway led us back to Castrol R30 or Shell R100.If the engine is indeed "making winning power" and being raced to win stick with the modern versions (degummed/rust preventing)castor based (Yamalube-R,Maxima 927,Shell R100 or Klotz Benol) oils at 25:1-40:1 ratios,32:1 still is the best for HP vs temp control..................as a shop owner building roadrace,dragrace and mx engines a few customers found the above statement was true after I told them,the hard way!............one customer turned the chrome blue and killed the rings in 2 1/4 mile dragrace passes on a perfect set of Yamaha TR3 cylinders using Redline 100:1,Redline paid to have the bores redone in Nikasil!!! Even Redline knows this 100:1 is crap............on the dyno an 11 second pull on a race ready Honda RS250 turned in to a problem when the engine pitch changed halfway through,turns out the Optimol oil cannot handle the big end bearing pressure,the "pitch" changed because both big end rod bearings were starting to brinnel in to the rod journals............in both cases without any other changes(other than the parts to replace the 100:1 damaged parts) castor based oils were used and no further problems encountered................................

My dear friend MARLIN.
If you use for YOUR reason other oils,...thats fine with me becayuse I never say YOU GUYS have to.
But please dont say OPTI 2 is crap(GARBAGE)That is just not fair.
I am using Opti lubes in my shop and on ALL MY bikes ,including vintage bikes where I cannot get parts for anymore,for over 30 years,without ever having a oil related brake down.Please believe me that as a Motorcycle dealer I can use any kind of oil on the world market,if I would find a better one then OPTI.I have witnessed in the PIONEER chainsaw Factory,the 50 hour non stop test on a chainsaw with opti 2 mixed 300-1.The reason for this test was to find the leanest possible mix in the saws,but still safe because the Timber people complained about the fumes blowing into there faces.After dismanteling the saw there was no wear to detect.
In a other case a customer of mine who used Opti 2 in his 2 KTM,s 500 MX for 2 years,during a conversation realiesed that he had mixed exidently 200-1 not 100-1.And again the engines after open them both for inspection,did not show anything wrong,and the cranks where baded in a good coat of oil.So again,if you dont like it ok,but please dont make 1000 s of users feel they are all wrong.Me included.
BTW.In 1962 I rode my first ISDT in Garmisch Partenkirchen Germany.
Before impound of our bikes I was approached by the OPTIMOL OIL company from nearby Munich,to use there oil-gas mix for free,and some money as a bonus and more money if I would win a medal.
They admitted to me that the mix was 50-1(at a time when everybody would mix 20/25-1)As a poor private entry I could use a good offer like that,and when they said,if your engine blows,we will pay your entire next year racing season plus a new bike,I took the offer.
After a 1/2 hour testing the new mix and adjusting the carb a bit I felt very good.The plug looked perfect.
The always critical cold,wet morning start was a 2 kick affair and the performance incredible.
Endresult was a Gold medal a 2. in class and a17.overall,and a great amount of money in my hands for the GOLD and following advertising.
When in 1969 OPTI was introduced to the CANADIAN market I begun to use it right away and never looked back.What was 50-1 in 62 had been improofed to 100-1 in 69.

..............my name is Merlin,and your chainsaw example illustrates my point perfectly,that same engine would have had the same result with straight gas...............................get it up in the 250 HP per litre zone not 44 and let us know how it turned out.................

Let's see , even a modern MX 250 putting out 50hp doesn't put out 250hp per liter.  Merlin, you make no sense.  How do you figure that a chain saw could survive with no oil in the gas ? A Honda CR 500 puts out maybe 55 hp but at a much lower rpm.  Ever hear of oil migration time ?  A modified CR500 putting out 62 hp (  which is much higher than a normal Open class bike ) doesn't come close to 250hp.  per liter.  A 125 would be the closest to this sort of stress.  I have seen plenty of 125s running 50:1 and surviving. With Optimol , I was running 80:1 with no problems in my Hodaka 125, 100, Zundapp GS125, Penton Six Day 125 and others.  I really don't believe in mixing in such a lean oil mixture but with Opti , I have seen no drawbacks as I have seen in other so called 100:1 oils.  OH, I was mixing my Aeroplane fuel at 100:1. Do you think that I would chance running a aeroplane engine on a product that I didn't think would do the job ?
I would bet that the example you stated was a problem with jetting and the fuel itself rather than the oil product. Most drag racers run as lean a mixture as they can get by with.  They don't care if it is on the critical edge of tune if they get the low ET. OH, by the way, I wouldn't run Redline in my chain saw either. So we are in agreement there. But don't compare Optimol to Redline. Different stuff.

...........well Dwight I guess it must be what world we live in,a modern 250 roadracer makes around 80 plus horsepower,works out to 320+ HP per litre(I was being kind before),as for dragracing if you have done it and been successful fill me in,I have done it but maybe I missed something...........run what you want,I could care less.............

Hi Speedy. I was wondering what Opti oil uses for a base stock? Is this a synthetic lube? Is this product available in the US, and if so what name is it marketed under. I have not seen it before. I'd like to thank you for some good advice you gave me a few years back ago at Mid-Ohio. Phil Ketchum introduced us. What to do with rusty fuel tanks was the question I had for you and your advice to use lead shot to coat the tank was most appreciated. Good advice for sure.

[Dwight Rudder]

Combative isn't he.
No, I never was a drag racer. But have friends that did and do.  I had friends who raced H2 Kawasaki to several records back in the 70s and 80s.  I still have a friend who is the #2 rated Top fuel motorcycle racer.  Chris Hand, Bike - "The Redneck Express".  But this is about oil not drag racing. Nor Road Racing. Different usage all together. I won't use a oil that Road Racers use as it is designed for extreme high RPMs and is usually pretty dirty. Most 2 stroke dirt bikes turn less than 10,000 rpm normally and need a clean burning oil so not to clog the spark arrestors and on modern bikes, powervalves.
I am not saying that Opti is the best oil to use but that it will do the job. I see no problem using it.  I don't believe in a couple of the other brands that say do the same.

...............I was going to let this rest after the last post I made but one point is being overlooked,a chainsaw was sighted as an example of a products vitrues,it was pointed out this was not a good example. The universal method of consideration in evaluation around engines/racing is HP per litre regardless of end use,period................you will no longer need to listen to my rants on this matter,facts are facts...............................

Geeeeez, I'm glad that's over!  Who wants cake?

Dwight,
  Please say Hi to Chris Hand.....cool guy, very cool.  Does he still have and run the Vance and Hines bike from the 70's?

And I thought "intelligent design" got people fired up. Interesting discussion though, and interesting to read.

Make mine just a small piece, holiday weight gain and all.

Hey Dave, while you are up, can I have mine ala-mode, with a scoop of "Rocky Road"? DOH!!![8D]
What a great set of postings! And I thought I knew something, I think I'll just stay with Maxima 927 40:1, Thanks for all the info!!!

Thanks for all the imput guys. I quess I can conclude from all of this:

1. I shouldn't use Golden Spectro in my power valve bikes because it leaves too much gummy residue. So now I only need to find out what oil leaves the least amount of residue at any given fuel/oil ratio. I assume the lower the fuel/oil ratio is, the more residue will be deposited.
2. I shouldn't use Opti 2 oil if the engine is being pushed to a power density of over 250 HP/Liter. I believe my 2001 KTM 200 EXC produces around 30 to 35 HP or 150 to 200 HP/Liter, so I can use Opti oil.
3. I should be mixing whatever oil is selected at 32:1 to optimize power because the oil helps seal the rings. The only problem with this conclusion is that all my bikes are jetted for 54:1 and I would have to rejet all my bikes. Also, if a lower fuel/oil ratio does produce more residue, then I am not helping solve my original problem of the stuck power valve.
4. A shot of cake will solve all interpersonal relationship problems.

So I guess I need to find a very clean burning oil designed for power valves at a 32:1 mixture. Please give me your oil selection suggestions and/or tell me why I don't need the 32:1 mixture. The most obvious answer to the last question is that I am an old, vintage bike rider and don't need the 0.01% increase in power that the 32:1 will give me because I wouldn't know what to do with it if I had it!!!

Thanks again guys,

Teddy

No, he is in process of building another bike. About a month ago he had his hand slip off the grip at 220mph and the wind swepted him off the bike. If he had been on the bike as it went through the traps,  he would have set a new world record. He is OK, only chipped his elbow and skint his hands some.  I think the engine is mostly OK but the frame was damaged badly.
Sharon ( wife and pit crew ) was all excited with the time until someone shouted that he wasn't on the bike.  Scared her to death.
