Shell Rotella 5w-40 synthetic........ T6 ???

[Gnuiser]

I now see the Rotella synthetic has a T6 designation on the jug for synthetic.

Is this reformulated?

The jug I bought almost a year ago does not have T6 on it. I'm getting ready for a few things for the bike next month and oil/filter is one of them.

Less zinc etc., so just wondering. I want to continue using the Rotella synthetic since I switched to it nearly a year ago. Want to get a fresh start when some nice weather streaks break loose. Hummm...

No idea, but curious as well since I will be changing mine with the same soon.

CJ-4 rating is the main change.

the last of the regular Rotella was also but they are just making the name change to show it. (they will be using a "T" number for most of their products)

It is Still very good Oil. HOWEVER, the requirement for a CJ-4 rating is due to EGR valves and coolers, and Diesel Particulate Filters being added to all new Diesel motors. It suspends soot better. But it has a lower Shear rating. (it is not quite as good as the pre CJ-4 oils.)

BTW
in addition to my shadow, I have a 98 12 valve cummins, a 2005 excursion with a powerstroke and a 2004 Jetta TDI.
I have wasted a lot of time looking into this.

Well I bought a gallon jug of the T6 stuff - now to sometime get around to changing the oil between now & sometime in May, whenever I get to it.
It says it is full synthetic base.
Energy savings - not conserving (no API note) they compare to 15-40.
Energized protection - okay, whatever...
I read somewhere online that it's shear strength is up to par.
It says it meets JASO MA, CJ-4, CJ-4 Plus and all that jazzzzz.....

Now that the weather is turning nice... I'd rather ride than work on it. But I'll have to leash down sometime before the hot weather starts to roll in and get-er-done. Done the plugs recently, so now oil/filter, final drive, air filter etc.

Is it ok to use this rotella 5-40 in my wifes 08 VT750C2 shadow spirit?

I have read elsewhere that it is supposed to use 10-40 and not use synthetic.

I use it with great effect in my VTX and would like to be able to use the same oil in both bikes.

Any responses would be greatly appreciated.

Some folks say not to start using synthetic in high mileage engines. Other than that, use it. The "5" in 5w-40w means it performs better at lower temps in colder climates. The "40" part is the number not to mess with because of of being watercooled. Not necessary to use 50w though some do, but I can see AZ summers beng an exception to that rule.

Yes. It will be fine.
It should perform just as good as it does in the other bike.

I would use synthetic, the only reason to not use it if is there is a pre-existing condition being hidden by deposits in the engine. Some rubber seals could be potential leaks if not for a deposit of varnish on the metal. But if there is no varnish synthetic oil won't do anything but provide you better wear protection.

So I just tried the first 40-mile run after switching to T6 on the last oil change. (Been running Mobil Delvac for years.) Biggest performance improvement I've ever seen from an oil change! Prior to this, I hardly ever noticed anything other than a little better shifting, particularly into 5th. Today the bike seemed to be smoother and more responsive, too. I'll need to rack up a few more miles to be sure but so far it is looking very good.

Besides, it will be nice to be running the same oil in my bikes AND my pickup.
