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

That is what I'm running because of the availability and the fact we've been using it for decades on boats.

I'm currently running 64:1 (after break in) and still have a slight oil drip.

Boat oil and Motorcycle oil are different and have different requirements. Boat motors run way cooler from being water cooled and their respective oil has a differant flash point than air cooled motors as two strokes go.
 
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.

When I discovered what I'd done I drained what was left in the bike, mixed up a new fresh batch of fuel and Opti, this time at 100:1 and it was like I had a different engine. Power increased noticably. No more oil dripping from the tail pipe and my plug cleaned up beautifully.

Just a word of caution to those who want to run more than the Opti-2 factory recommended 100:1, be prepared for the consequences.

wait a min till i can see... eyes are all blurry from reading god knows how many pages :s

OK, so let me get this straight...
this stuff runs at 100:1 the same as my Castrol does @ 32:1??

sounds like it works awesome. however im not sure that it is supplied in canada.


EDIT:
i stand corrected. it IS in Canada :)
ill have to grab a bit for my next mix
 
So it's not the AMOUNT of oil, it's the QUALITY of the lubricant that's important.
I've used Amsoil Saber 2 stroke oil as lean as 175:1 - and it runs great - Amsoil claims it's passes the test at 300:1, but they recommend 100:1 because no one would believe 300:1.
 
I have Opti 2 for my Indian, what mixture ratio do I use to break it in ? doe's anyone know? everyone seems to give an opinion what they have used and like but no one say's what the mixture ratio is ? for the break in period with Opti2 on an engine that has never been run.
 
truckd,
If you read into the posts as far as I did you would see that a lot of people have started a new engine with Opti2 from scratch and broke it in at 100:1.
Or if you don't want to take that chance you can break it in with regular 2 stroke oil at a regular mix ratio and then change to Opti2 afterwards

Some people here say that your engine will immediately explode at 50:1 under load.
 
Amsoil recommends 100:1 for break-in and regular use after that with their Saber 2 stroke oil - so nothing special for the break-in period.
 
Thanks for telling us how you solved your mystery 2Door.
My dad got me some supersized 'ketchup packets' of Opti2 when he went to Maine a while back, but I have some Echo powerblend 50:1 I intend to use up first.
So, If I go to the 100:1 from 50:1 will have have to shrink my jet hole?
(because of the richer fuel ratio)


Oh, and this thread again that refuses to just die! ;)
 
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.

I have 3200+ miles on my Raw Moters 66cc using nothing but Opti2 from day one.
I mix according to the directions on the bottle. And I use the same fuel for my landscape business, Stihl chain saws, trimmers, blowers, etc. with great results. This stuff is the best, all landscapers I know use it exclusively.

hi me too.
i broke my 66cc engine from the start 100:1, and i sold the bike with a 1000 miles on it and it ran fine. i never did seam to have a break in, ran like a striped assed ape right from the start. i pulled the head befor i sold it look like new.

i just got a HF 79cc Predie i am going to pull the side cover and clean it out an fill it with opti 4 to break it in..

Tnx for the advisory on a mix goof, Tom!

I don't run the Opti2 yet, but I shall. :-)

I goof up with my mix fuel from time to time and usually just dump it into my roto-tiller or the lawnmower, on top of what is already in there...

got a 16oz bottle on order. Will be picking it up Tue or Wed. once my current mix is complete, Will mix up only 1gallon of Opti just to see what my wheels do :)

warning: Be wary of the dealer list on their site. called 6 places and only 1 had even HEARD of Opti2.
had to call the 888 number to get list of some good dealers in my area.
on a good note, brad was on the other line when i called, but the receptionist was super helpful :)
 
Guys, if/when you decide to use Opti-2 you might find that the reduced oil content will result in a rich fuel/air mix. Remember when you reduce the oil ratio you effectively increase the amout of gasoline to the mix. More fuel can result in a rich mix.

I rejet my carburetors to adjust for that change. I'm also at 6000' MSL so that plays into the equation too. Depending on your elevation above sea level your experience might differ.

All I have ran for quite awhile now is the opti-2. My lil china girl 2 smoker seems to love the stuff. However I do run mine around 80:1 only because of the size of my can. I dump one of the packets that is suppose to make 2 1/2 gallons into 100:1. However my can I use is only a 2 gallon can...so I just do 1 of those packets in my can and fill it to a bit over the 2 gallon mark. I wouldn't be afraid to mix it to 100:1 if my can allowed for it. Good stuff!
 
I'm still working for the ground crew with the State Capitol Commission.
This year we decided to phase out our 2 cycle mowers. These mowers are 02 models, Toro Commercials, with Kawasakl motors. The reason for the phase out is the chasis have been hammered pretty hard. We put more hours on these mowers in 2 days than most home owners put on in a year. So we decided not to recondition the chasis. The engines have been run on opti-2 oil mix 100/1 in the last 4 years and they still run sweet. Personally I hate to see them go. I hope I can get one when they are auctioned off. These must cost about $1600 when new.
I guess this tells what the opti-2 is good for. We also used regular gas with no corn juice. I hope we can run opti-4 in all the new 4 cycles.
