Hey Scotty!
I have a 2000 Toyota Corolla VE (1ZZ-FE engine) with 153,600 miles. I inherited the car from my father and I took possession of it at about 135,000 miles. It seems to burn about a quart or two of oil by every 5,000-mile oil change. I use top-tier gasoline and use premium oil. I've also changed the PCV valve and timing chain tensioner, but the oil consumption remains. I did notice that there's a considerable amount of black soot when I wipe inside the tail pipe. What other causes could there be for the oil consumption? What other options could I try to remedy, or do I have to live with it?
Thanks!
What other causes could there be for the oil consumption?
Engine wear. (The thing is nearly 25 years old.) Stuck oil control rings.
What other options could I try to remedy, or do I have to live with it?
You could try ATS Carbon Clean which Scotty recommends.
