Need some guidence- Newb
 

Hey, so i'm currently looking at purchasing a 1987 RX7 GS non turbo. I have heard that rotary engines take a beating in cold weather and I live in ottawa so we routinely get -25-30C weather. Would it be possible to keep the car running during this kind of weather without completely messing it up. I was also wondering if you guys could give me some reading material on how to improve reliability, proper maintenance, and if their are any rebuild articles out their taht would be great. Thanks a bunch and hopefully this will point me in the right direction.

all the info youre looking for is here already...you just have to look for it.

Ya, i've found everything i'm looking for except my winter question.

FAQ on oil...

In starting and operating temperatures below 20F, use 5W30
In starting and operating temperatures between 0F and 80F, use 10W30.
In starting and operating temperatures above 30F, use 20W50

For rebuild, you should get a video, and there's a thread in the archive on what parts you'll need for a rebuild.

Have you visited the Canadian forum? There are plenty who drive their car all year around (though I don't, due to the massive amount of salt on the roads). Nothing fundamentally wrong with driving it in the cold. Mazda designed these cars to be used all year around, and like any car, as long as it is in good shape, then winter driving is no big deal.
