hey guys some of you may know me if you visit the first gen sections at all.
i own a 1980 rx7 sa and picking up my 05 rx8 monday.

i wanted to say hi and ask a question or two.
the car i bought is a 05 grand touring model. it has full leather interior, nav system ect. its spouse to have all the options, so i should have the in dash 6 disc changer. how does that work?

i live in mass and wanted to know what type of oil you guys would recommend to run during the winter. i read about some omp problems and iam a little worried about that now. so i think i am going to run premix. can some one recommend a premix oil that's easy to buy ie i can walk in to a store and buy.

could some one post a math equation(i suck at spelling) so i can figure out how much premix to add when i fill up.

and one quick quick question i never had to worry about emissions in my 7, when i go to get the sticker wont the premix make me fail.
