Anyone running this? I have it in my bike now but i just noticed it isnt MA rated but it says on the back of the bottle for transmissions and wet clutch primaries. I called mobil 1 and they said "thats what its for" wet clutch bikes and seperate trans bikes "Harleys". I just thought it was odd that its not MA rated. Am i missing something??

Awww crap. Quick reply before it all hits the fan.




I am running this as we speak but im switching to the 10w40 racing version next oil change. I had intended to get the mobil racing before and wally world was out, so got the v-twin. It does just fine, clutch shifted better than with non synthetic. I noticed a small amount of burn off but that is probably with all oils. Just switching to the other because I like the front graphic better!




I know I'll get corrected, but im sayin' it anyway. I think the mobil racing is actually more formulated for our bikes where as like you stated the v twin is sort of wet clutch/separate trans multipurpose oil that will do OK. Like duct tape can tape wires, but not as good as electrical tape.

First, Mobil introduced MX4 to the offroad motorcycle and wheeler segment in North America, so the MX4 moniker actually made sense.



Second, Mobil put the MX4 in Racing 4T bottles and sold it to the rest of the world. MX4 and Racing 4T were exactly the same product.



Third, the V-Twin oil was introduced in North America with the V-Twin moniker a reflection of the most popular engine type in the market. V-twinners tend to like heavier oil viscosities, not that they actually need them. The V-Twin oil rated favorably in independent testing, right up there with the best specialty brands like Royal Purple and Amsoil, far better than any other commonly available brand. V-Twin lacks JASO MA certification because the standard did not exist when the oil was first formulated.



Fourth, MX4 was renamed Racing 4T because the rest of the world calls the stuff Racing 4T. Same stuff.



With the passing of time, MX4/Racing 4t (same stuff) needed to be upgraded to new additive technologies already applied to the newer V-Twin oil to maintain its performance level above the commonly available competitors. The oil changed, the label name didn't. Essentially, the V-Twin additive package was used with a 10W-40 base oil instead of a 20W-50 base oil.



Hence, we now can choose from two of the best motorcycle oils available anywhere at volume prices. Choose which to run based on riding conditions and type of riding to be done, then pour with confidence.

good info there qwerty...i hate how they changed the name multiple times...they could have at least put a note that said (formerly mx4t)...i remember being a little puzzled when i went to get oil in the spring a few years ago...i run Mobil 1 Racing 4T ( http://www.mobiloil.com/USA-English/MotorOil/Oils/Mobil1_Racing_4T_10W-40.aspx ) in my TW and i ran it in my CBR as well (noticable difference in shifting switching from regular oil to full synthetic in the CBR)...running a different synthetic racing 4T in my sumo...
