What 2-Stroke oil do you use?

I think most of the oils today are quite good, and I would run any with the exception of Yamalube. Why you ask no Yamalube, tear a sled down thats ran Yamalube for a couple of years and the carbon on the dome will be so thick you have to use a scraper to get it off. Today it might be good oil I won't use.
I like Redline oils, all of them the 2t, fork/shock and gear oil.
Phillips makes a good inexpensive oil that performs well, I use it in my sleds and have for years.
As for gas, I prefer VP, and yeah I've done my research and have much seat of the pants testing. For those running AV gas 50/50 I don't see any problem, I don't believe you get the performance potential you could, but then for most people the k5 has more than they need anyway. I run C-12 in my playbikes 50/50, in my nitrous bikes C-16, in my 500 comp bike I use Q16 and in the 4t MR12. Its expensive but if your looking for performance then you have to pay, no way I'd run this stuff for play bikes.

my thoughts exactly regarding the yamalube comment above..i have been out of 2 strokes for a while, but in the past have had IT-175, KX125, CR250, and KX250(94)...I used to run yamalube waaaayyyy back when until I tried using bel-ray mc-1...my bikes always seemed to run better with that oil and that is what I stuck with. I would mix it a little leaner, closer to 40:1 and never had any issues with motor problems whatsoever, and the spooge factore was much less than the yamalube-also much less smoke.
Fast forward to last month, when I picked up a '99 KX500...previous owner gave me a bottle of yamalube and said that is what he has been running, so needless to say I will be draining whatever gas is left in the bike! I have some new H1R and some Maxima that I picked up, so I will be trying those oils. I am also considering tearing the head off and inspecting the power valves before I go much further as I am a bit concerned that the yamalube (and questionable mixture ratios + factory rich jetting from PO) has things gummed up.
I am expecting to run the H1R @ 40:1 with some slightly leaner than stock settings on the carb when I get time to play with it some..its been hotter than hell :evil: here in texas, just can't get motivated to work on the bike yet.
DeadRinger:
Motol 800 approved for catalytic converters. 100% synthetic Thats what I always run. Rotory guys put a little in to lube there apex seals.
Polar-Bus:
Back before Klotz back in the early 80's I ran Golden Spectro, good oil for the time and I did loose a few top ends, but not sure as I could blame the Golden Spectro on lack of oil performance. Back then I was young, 2 stroke green. and stupid but "kinda" fast LOL .
The only oil I was not impressed with was Bel Ray MC1, that garbage leaves a ton of carbon spooge behind.
Good:
PB, that's surprising, a lot of people like that stuff.
