Hello all. I have been reading this site for a long time and recently purchased a 1989 CRX HF with 210,000 miles on it. My first test of the car resulted in 43.75mpg 140 miles on 3.2 gallons. I recently discovered a large vacuum leak in the PCV valve hose and the valve itself was pretty gummed up.
Just gave her an oil change and tomorrow I will fill it up and have my second mpg average, however I expect it to be low because of the vacuum leak and because I let it run for a half hour or so testing other repairs.
Nice site by the way, it looks like you all are pretty smart when it comes to fuel economy and I am eager to learn from all of you.
You can do it! How's it running? I'd shoot for a general tune up, should be posting a bit better numbers I'd think.
The thing runs great.. I knew my mpg wouldnt be that great this round. because of the vacuum leak and a bad PCV valve plus my driving habbits were not the best. Also I left the car idle for 1/2hr to an hr testing the radiator for leaks. My tires are at 40 psi so I think I am going to inflate them to 50psi tomorrow and hope she is not too rough
