    I think in this case it's just a marketing term.

    The entire mixture reacts under temperature the same way (melts and solidifies), this means different substances in the oil all react at the same temps, instead of different substances reacting at differing temperatures. The result is a superb lubricant in Opti2's application.

    eu·tec·tic/yo͞oˈtektik/
    Adjective: Relating to or denoting a mixture of substances (in fixed proportions) that melts and solidifies at a single temperature that is lower than the melting points of the separate constituents or of any other mixture of them.

    Opti-2 makes the claim that their oil is different due to it's "eutectic" properties, which they describe as improving the surface metal of the cylinder wall instead of just lubricating. They have some info on their website showing it actually smooths the metal surfaces, thereby further reducing friction.

    To me, it sounds awefully snake-oily, but I have been using it with great results so far. Engine runs great, NO smoke and NO oily splatter on wheels and frame.

    One more Opti-2 option for people who can't find it. Yesterday I was in my local Family Farm store (similar to a Tractor Supply) and they have opti-2 but also another product called US2 oil. Sold in the same 1.8oz packets, same mix of 1 packet to a gallon, and same fine print that it is made by Interlube, makers of Opti2.

    Their site (us2oil.com) shows all the same marketing stuff as opti including the "3rd generation oil".

    i was running opti-2 @ 72:1. the plug looked like it would like less oil.
    i went to 100:1. before i was getting about 30-32mph.
    now i got up to 35mph. i wasn't even really trying it might have let me go faster if i tried.
    before switching to opti-2 it took about half a block to start.
    @ 72:1 it took about 15 feet.
    @ 100:1 it starts with any enough effort that turns the crank.
    i'm loving it.

    Heck, since going to opti2 I can start my bike by pulling on the tire with the back wheel off the ground and the clutch engaged.

    A lot of that is carb jetting too. At sea level where you are that richer fuel you are getting is prolly what the Doctor Ordered per say

    Doggone if my CAG engine just does not like Opti-2. Ran it for the first time with the new piston and cylinder and it overheated again at 36:1, but did not seize or score. Could not restart until it cooled off. Called Duane at Dax and he said to go with Valvoline at 20:1. So no more Opti for this engine. Have not run it yet at that ratio. Been too busy with the engine rebuild on my 1990 Geo Metro.

    Love the geo metro!

    Just wanted to pass on that the opti 2 guy told me that if you run it at ratios higher than 100:1 like even 80:1 he said it would actually run hotter. Not sure if that's what happening here. Just wanted to throw it out there.

    Hi GEJoe

    Thanks for sharing, and don`t take offense, but why would mix 36:1?
    Too much of a good thing.

    Keep us posted if you would. Thanks.

    i was running mine @ 71:1. changed over to 100:1 & it runs better.
    i would imagine running it @ 36:1 would be bad. because @ 71:1 i was having a lot of build up on my spark plug even though it was a great caramel color.
    you know if there is too much vitamin D in your milk it works against your bones.
    can't really blame opti or the engine if using so much oil.

    36:1 Opti2 is not how this oil is designed to work, mix it @ 72:1 (1.8oz per gallon) tune the carb right and that cag will run like a champ.

    My opinion is that at the 36:1 ratio that engine isn't getting nearly enough fuel and you are having a serious lean condition.

    But as with many things to each their own, I persoanlly love opti2 and run it in every 2 smoker I own with ZERO issues, they all run great, minimal to no smoke, very low odor, and great throttle response with great revs at the top......what more could anyone want?

    It's all in the tuning with any 2 stroke with any oil......!

    Peace, map

    Well, after reading through this brick of info that would fill a dictionary, I believe I'll give it a try. I don't about finding it locally though, if not there's always flebay! I got a lol at the tag, epic redundancy! Very fitting!!

    I parked my bike next to a bike running opti 2 and when I came back I had a flat tire, so I would never use the stuff.

    Glad you liked the tag. I had followed this thread from the beginning and then it got resurrected, again and I just had to tag it in that manner. What in the world can anyone possibly say that hasn't already been said 3 or 4 times already in this thread.
