I just got a new job that would require driving my 82' 245 100 miles per day. The car runs great, but I'm still worried about potentially getting stranded because of it's age. What steps should I take to maximize it's reliability?
Also, I'm only getting 15 MPG. What can I do to maximize my MPG?
Thank you

 

Has it had a tune up lately?
You might want to have all the adjustments looked at good.
You should have mechanical injection.Make sure all the adjustments are set properly and you should be fine.
