Buddy Cole Posted February 6, 2007 Share Posted February 6, 2007 a good thing to run through your car every now and then is the Guarenteed To Pass stuff that helps with smog. it cleans cylinders and valves and works. word. but 15 mpg? damamn. something is wrong there.

Ben. Posted February 6, 2007 Share Posted February 6, 2007 You're getting the same MPG as my truck in the city. I have four more cylinders and an "unusual power steering whine" under WOT conditions. Something is BAD wrong with your car. Get it tuned up, ASAP. Link to comment Share on other sites More sharing options...
