I use it in my bikes, motor home and generators. It is the best oil I have ever used. When I change my bike oil, the old oil looks very clean and thus I know I have good protection.
The oil T4 was good , but the newer T6 is great.

Lubrication freaks howled in agony when SOPUS switched the syn 5W-40 Rotella T name to the new T6 designation around 2012 IIRC... "They ruined it!" and panic ensued to stock up on "the last of the GOOD stuff".
VOA analysis by me and others saw a slight drop in ZDDP , a bump in Phos, Calcium, yadda,yadda, in the "new" T6 formulation. UOA proved otherwise, and it was the best damned overall formulation to date concerning wear... Incredible HTHS,,, 4+ range with decent flow on cold start.
The old 5W-40 Rotella T didn't even have a JASO spec for wet clutch operation, yet smart folks were filling 2/4-stroke transmissions with it based on VOA and UOA.. Thus the legend was born for Rotella T 5W-40 synthetic.
I found an old "Humpback" Rotella T synthetic 5W-40 jug half full in my basement the other day, 2009 date. No JASO-MA spec at all. The label slogan says "Shell Rotella T. IT BELONGS IN YOUR TRUCK".®"
Shell Rotella T6 5W-40 MEETS wet clutch JASO MA/MA2. Pure and simple approval. Not ambiguous "Meets or Exceeds" marketing bullshit.
Shell Rotella T6 5W-40 is arguably the best overall oil ever for me... YMMV. I began using it around 1995 in the various formulations. Here is a range of engines that it covers, approved oil rating or not. Your call there. All these still run. WELL. I guess I take risks, but base them on oil composition/formulation.
1983 Tecumseh 3.5
1998 1.9 VW TDI
2003 VW 2.0
2004 VW 1.8T
2010 Kawasaki FJ180V
2012 Honda CV160 x 2 Commercial and Industrial
I just rebuilt two Honda CR125 engines to include full clutch rebuilds/cranks/every bearing.... Ran the Pro Honda HP Trans for the heat cycles and short rides... Rotella T6 5W-40 forever henceforth until I need to evaluate another reformulation.
Best bet? Consult your manual.
