My 88 90 has some oil consumption. After about a month and a half of about 2500 or s miles, it runs abut 1/2 quart low. This is the summer and this car does get highway speeds up to and including 80. Normal, not? I see no apparent leaks and my car doesn't ever smell like something is burning. No emmisions either. Just curious. Thanks Rob randrews@post.smu.edu
