I know have 11000 miles on my z. up to this point i have been just putting the regular oil in at the dealership. I am wondering if it is worth it to finally go synthetic and if it is is it ok to do it soon or should i wait untill it has a certain number of miles? next important question? what other synthetic materials should i add in addition to engine oil. (ex, differential, transmission) and will all these synthetics add more horsepower to the z. and yes it is a 6-speed. thanks. swc
