Ya, but the dino Rotella comes only in 15W-40 or 10W-30.

I have seen people using 15W-40 in the summer and then half 15W-40 and half 10W-30 in the winter.

Too much wringing of hands and gnashing of teeth going on here.

10/30 will be fine in the winter. 15/40 will be fine in the summer.

Or just use what the previous owner was successfully using.
