I'd been using T6 5w-40 for a few years as that weight was what BMW spec'd for the R1200 water cooled bikes. It worked fine in my other bikes that I used it in and the mowers, other than my air cooled mowers tended to consume a bit more than they did when I used M1 15w-50. When Shell brought T6 out in 15w-40 I started using it because 15W is plenty low for start up here and it would have much less viscosity improvers than the 8X any 5w needs in order to flow as a 40W.
The result has been the bikes don't care and the air cooled mowers seem to like it more, and they're back to not using any measurable amount. The CB1100 runs and shifts as smoothly as ever, probably better than with Honda 10w-30 and T6 5w-40 *after the oil has been for a couple thousand miles*.
