Am losing oil, about 1+ quarts/500 miles. (Think it might have first been noticed 3 yrs ago/30k miles ago- oil almost empty at 3500 mile oil change- but I assumed then the last oil change was done inadequately.). NO smoke from tailpipe, no oil in tailpipe. NO oil in driveway, mechanic said bottom of car without evidence of oil leak-clean. Performance appears relatively unaffected at this point. Mechanic said I'm possibly losing oil into the engine. Was told performance would eventually diminish- "should look to replace engine"! PVC valve change? Worn piston rings? Valve seals not functioning properly? I'm a female and lost with how to proceed. Want the most logical, frugal way to approach diagnosing problem, and want to know est cost of possible problems it might be
