Rotella T6 Alternatives?

Never seen any published JASO list containing 323 oils certified to defeat wet clutches either...
What in the Heck are you talking about, there is no standard to defeat a wet clutch, cause its a stupid statement.

There is only a frictional gate to offer grip for a wet clutch, Jaso Ma MA2 ratings

Will an Jaso MB rated oil cause issues in some cutches on the limit of design capability? Absolutely!

Are there oils not rated as Jaso Ma Ma2 that actually work as well or significantly Better, Absolutely!

Im been very pleased with Mobil one super 1300 15w40, and its been tested with a High stressed clutch pack on the limit of capability, which means it will work very well with ANY motorcycle wet clutch , fear not.

People dont seem to realize, how much mechanical load a clutch Pack can take, will effect which oils can create mild slippage issues.

That mechanical load is going to vary amongst Motorcycle models.
 
Although Shell says T4/T6 meets JASO MA/MA2 specs, for my SE6 Can Am Spyder, it doesn't meet BRP specs. Not really a concern unless someone is worried about warranty issues,
XPS Recommended Engine Oil 4T5W40 Synthetic blend oil. If the Recommended XPS Product is not Available, Use a 5W40 4-stroke SAE synthetic engine oil meeting or exceeding the following lubricant industry specifications: API service classification SJ,SL, SM or SN. Always check the API service label certification on the oil container, it must contain at least one of the indicated standards.

Correct, but Rotella T6 doesn't show API SN rating.
You are right ... however SM is accepted . But strangely ... Jaso is not mentioned .... they are so confused , I have 4 books in front of me and one cant get a clear answer ... they really want to sell their overpriced junk ... so frustrating

Negative... its not a list of 323 certified oils to defeat a wet clutch...

Motorcycle oils meeting JASO MA and JASO MB also make no mention of defeating a wet clutch...

JASO MA
Valvoline 4-Stroke Synthetic Motor Oil 10W-40 and 20W-50
Mobil 1 Racing 4T 10W-40

JASO MB
Red Line 10W-40 ester based motorcycle oil
Silkolene QUAD ATV 5W-40 Fully Synthetic 4-Stroke Engine Oil
The Guy you are replying to is correct. Jaso MB is not for a wet clutch , Only the MA rating meets the frictional gate, that jaso MB rated Motorcycle oil, is not meant for a wet clutch, But can be run in an engine, that is seperated from transmission wet clutch area.

Have I ever had a wet clutch slip on Redline Jaso MB rated oil ?? ABSOLUTELY!
 
Ive not really not come across any Diesil oils that caused clutch slip.

I have a motorcycle where the power out put stresses the clutch limitation, so too slippery an oil, and it will slip.

but the super 1300 ( even if not rated), is amongst the best with clutch grip , and is a semi syn. Mobil has a full syn diesil, but never ran it, mainly for risk of clutch slip, not in a hurry to try.
 
I have shared this before, diesel oils are pretty much the same. There is no magic or black magic pixie dust that makes any one of them more or less suitable for motorcycle. This becomes very entertaining at times the way this gets washed, rinsed and repeated.

Might try Delvac 15w40 in my VT750s if the Rotella T4 becomes scarce or pricey.

One reason I keep coming back to the T4 15w40 is that it has worked in every bike I've put it in over the past 25 years.

It’s been a while haven’t owned the metric bike since 2014 but I ran across your post and needed to comment.
I’ve tried many oils in my Suzuki and Yamaha bikes and my favorite was Super 1300 15/40

Summertime I would use a different brand 2050 just because it gets so darn hot here but other than that in my mind from what I remember, I actually felt the super 1300 was grippy for like of better words
 
Too much controversy and changes. Switched to this:

the problem is the price of super tech 10-40w 4 stroke oil has jumped to just under $9 a quart/ $36 per gal (up from $5.86 per qt less than 3 years ago) while oils like rotella t6 15-40w (which is api sn & jaso ma/ma2 rated) is $26 per gallon and spec wise 10-40 and 15-40 are so close it won't make a difference unless the bike is being ridden in extremely cold weather, plus i don't know about you but it really pisses me off that, just so they don't have to report a lower corporate annual gross sales figure to share holders from the 300 stores they closed walmart is artificially inflating prices throughout the remaining stores to compensate for the gross revenue they lost by closing so many stores besides, like super tech oil @ $36 per gal is worth more than branded oil from real oil companies....

Can't say I have seen a 10w40 or 20w50 Super tech MC analysis. I have used and posted a few times with M1 10w40 4T and 20w50 V Twin. M1 leaves nothing to be desired, and to me are the benchmark for shared sump oils.

I got Valvoline full synthetic 10W-40 motorcycle oil on Amazon for less than that per quart.
 
My bike only needs 3 quarts. Doesn't feel as bad. I wish they sold it in gallon containers, would be less.
I'm going to keep using it, shifts great, runs great, can get it easily.

So…

Take your dollars elsewhere?
 
I just noticed that the new Rotella T6 jugs no longer say anything about meeting JASO MA2 specs. I've been running T6 a bulk fleet oil for multiple applications. KTM 300 XCW dirt bike, Kawasaki KLR110 dirt bike, Suzuki King Quad four wheeler, Yamaha Grizzly 90 four wheeler, John Deere commercial mower (Kawasaki FX801V), LS compact tractor, and a 2005 Jeep Wranger 4.0L.

Did T6 change it's formulation so it's not longer acceptable for wet clutch applications? Is there anything alternative that I can use for fleet use? 15w40 is what I always used. I live in the midwest and all vehicles are stored in an insulated shop. About half of the equipment only gets used in the summer months exclusively.
The 15w40 semi syn super 1300 mobil 1, I have no issues with.
