We have a 1994 Toyota Corolla we got for our oldest girl. It uses about 1 Qt of oil every 900 miles. But it does not smoke at all. It has great power, Great pick up and great top end speed. It has no leak at all. Set on newspaper for 24 hours, no leak. Took to two shops. Told this motor by toyota had a problem with burning oil inside. I needed a pvc and something drilled out? $100 a pop. Stell using oil. Can you please tell me want is going on. What do I need to do.
