Yamalube 2S or 2R?

Was wondering what the difference is in these two premix oils. I bought Yamalube 2S and it was $16.00 a gallon a whole lot cheaper than most other premix oils available. My uncle told me that Yamalube was a good choice for my 98 YZ250. I didn't know which one to buy and didn't realize it was that cheap until I got the invoice. Is this a good quality premix? Any suggestions on a good clean oil to use. Any help would greatly be appreciated.

Yamalube 2R is a great oil, it is my preference. Yamalube 2S is one of the dirtiest, spoogiest (is that a word? ) oils that I ever tried. I tossed the whole bottle after one tank of the stuff.

Thanks for the reply Spanky, that is probably one area that you don't want to skimp on. That was a waste of money. Anybody want some premix?

While I certainly don't know what the difference is between the two, I know that the 2S is marketed as "injector oil". So why (anyone?) shouldn't 2R be used in injector systems? Or this just another tricky marketing ploy?

Oh man Yamalube 2-S is the crappiest stuff I ever tried just like Spanky has said. It's more of a injector oil for a little PW50. :silly:

Most premix oil brands have 2 different types. One for high performance engines that is pricey and a cheaper injector/premix oil for smaller low performance applications. Yamalube 2-R = racing oil for high performance engines, Yamalube 2-S = cheaper injector/premix oil for low performance engines. This is theory...

Yamalube 2S is the semi synthetic blend "injector" oil. The "R" is their full-on synthetic race oil. I personally have good performance from the 2S in the kiddies BW-80,(the ULTIMATE test vehicle), low smoke,low spooge, but it is injected so your premix results may vary...

I ran 2-R in my bikes for years . Good protection and it runs as clean as anything I have found

Hate to burst your bubble, but 2-R is a semi-synthetic, it even says that on the front of the bottle.
This is why I switched to Mobil-1 MX2T. Its a full synthetic that's cheaper than Yamalube 2R and I still mix it 40-1. I was a true believer in 2-R until I ran across MX2T.

Mineral based injector oils usually have a different dilutent makeup. Basically they have to control the pour point to keep the paraffin content of the oil from compromising injector flow at lower temperatures. Lower priced oils tend to have have higher paraffin contents and need greater volumes of dilutent to control low temp flow. This isn't to say 2R can't be used in an injector, it's more a case of consideration for these issues may not have been specifically addressed during the design phase.
I ran 2R in road race bikes for years and was always very pleased with the results.

Thanks Rich. I use 2R in all of my 2-strokes, except the injector equipped ones. Never knew why I needed an injector-specific oil for the PW's; maybe I don't don't. Maybe I'll do some experimentin' (on the PW80 and the Blaster) with the various oils littering my garage from my son's past sponsors
