Cheap 2 stroke oil vs expensive brand name. Any difference.

I tried searching for this before posting, would have imagined it would have been asked 100 times, but found nothing.

Is there really any difference between 2 stroke oils? Are the fancy expensive brand names actually better, or is it just hype and/or placebo effect?

I have a '93 kx250, that I have had for many years, I've used the kawisaki 2 stroke oil, castor 929, yamalube, etc 2 stroke oils. Back when they costed $6 for a quart I thought it was a ripoff, but dealt with it. Nowadays the nearest bike shop wants over $12 a quart for 2 stroke oil. Ridiculous! I bought it since I was in a pinch last time, but I never want to pay that price ever again for a quart of oil. I've seen 2 stroke oil at wal-mart for like $2.50.

Is there actually any legitimate difference between genaric 2 stroke oil, and all the fancy racing bike oils? Or is it all the same stuff with different marketing?

It can't be that much different right? I mean all it does is provides a quick moment of lubrication in its brief life before burning up.

Would some genaric 2 stroke oil be just fine for my bike, or a bad idea? It would be one thing if I was racing or something and needed every little .05% extra power, but I only ride for fun, mostly trails, splashing in the mud, hill climbs, jumps, etc. Just general all around riding, on an old '93 kx250. As long as I'm not fowling plugs all the time or running poorly I'd be happy.

When it comes to the better brands, your pretty safe no matter what, but when you get into the really cheap crap, stay away from that. A lot of that "value oil" is cheap shit.

I buy castor 927 at ~$20/qt. Mixing at 32:1 costs you $2.50 worth of oil per gallon. So a good "expensive" oil is still cheaper than the gas you are mixing it with. Would you use water instead of gas because gas is horribly expensive?

That brief moment is an opportunity for your piston to burn up, or the oil. I'd choose the oil.

If you can't tell already, I'm a big fan of good oil. My dirtbike (yz250) is stock, gets only castor but could probably survive on less. My moped is modded from 49cc to 80cc and I'd rather push it home than put in cheap oil. It's not really about gaining/losing power now, but preserving your cylinder/piston so you don't have to buy a new one.

The Yamalube is good stuff. Ran it in all my bikes. Stay away from the cheap stuff. Your silencer and rings will thank you. I am using some pre mix that my buddies use on their shifter carts right now. I will try and find the name.

Found It.

Maxima 927 Castor $8.99 for 16OZ I like this even better than the yamalube.

speaking from personal experience building my own kx and others for race use, they tend to carbon up pretty bad in the power valve chambers so if you can find an oil that creates less carbon deposits, thats the ticket. you'll go a bit more between top-end rebuilds as well

you figure the lubricity and sheer strength is gonna be different under fire than it will be under the load of bearing and gear surfaces and since the crank pocket is sealed, whatever oil you mix will never see the bearings or gears..

i'd rather run good stuff than NOT, but the cheap stuff will always get ya by. i've had customers who explicitly use the cheap shit with no problems too. it's all in the riding style and maintenance as well.
gonna beat on it? you can probably get away with a cheaper oil.. gonna woods ride and put around? you'll want something less prone to carbonization since you're at or near idle longer.

Thanks for the answers. Guess I'll just stick with the yamalube and castor 927 stuff or whatever, but I'll just have to buy it out of town from a different bike store.

My local bike store, Renton Motorcycles RMC sucks, and I think they rip you off on purpose. They are one of the biggest around, yet they only have one single cashier in the entire parts, oil, apparel, gear, etc department, never seen more than one (and there is only one booth). And they never put the price on any of the oils. You can't ask how much it costs either since there is always a huge line since there is only one cashier. So you basically have to grab the oil and stuff, wait for like 10-30 minutes to checkout, and then get slapped in the face with the suprise price like 12.95 or something for a quart of yamalube.

And by that time your probably running behind from standing in line so long, don't have time to go 1-2 cities over to the next nearest bike store, and need the oil, so you just buy it and walk out of the store in shame because of how bad you've just been ripped off. I really think they set it up that way on purpose.

Ditto. My RM loves the stuff, or at least did before I cracked a water jacket.
