I don't know about if the F200 oil is synthetic or not, but will see if I can determine if ... I think the big difference is that it is multi-viscosity. Hey, multi anything has GOT to be good.
And yes, the stuff can be run year round, at least in cooler climates like mine. Some where I saw a recommended temperature chart, but can't seem to put my mitts on it now. Sad thing when the brain freezes ...
