Thanks AndrewJ.
Definitely yes on synthetic. I've read a lot about the sludge issues. I've always run 10w-30, should I go thinner?
About aero - the aero threads are definitely the most fun. Since every car is different, I would really need to experiment for myself. I love this idea, I just think that since most of my driving is in the city, the gains would be minimal.
