You're not supposed to get more than about 1.0V drop across the gpr, so yours is at least adding to your problem, if it isn't the whole problem. I don't run synthetic oil, so I'll leave that question for someone that does.

For the synthetic - I personally wouldn't run it any longer than regular oil, unless you get into the oil sample testing thing. I put synthetic 5w-40 in my truck for the winter, and I will change it at the 5000 mile mark just like normal. Just my $.02!
