Yes, however, once you start to change the performance characteristics of your engine, the Toyota suggestions go right out the window.

I use a 15:40 synthetic myself.

That isnt true. And they arent suggestions, but specifications. Unless you radically change the rpm limits and how much time it spends in that range, there is no difference.

Better yet, stay with a straight 30 weight for winter

A truely good way to get rodknock. Nothing like pancake syrup type viscosity when it is 20 degrees out.
