I have a gen 1 us spec crv. On a good day i might get 300 miles to tank. Can anyone tell me if thats the norm?.The crv has over 155,000 on odometer. Should i use a higher octane? Any feedback would be appreciated.Just wondering what is a decent mpg for the Gen#1 1998 CRV 2.0, 5speed 179,000 miles, would be. Wanted to see how she was running .
