Hi. I have a1999 Toyota Camry, same engine as 2000 Camry. I have 201,000 miles. I travel 110 miles a day. I think it is normal. Every 4 days, I add about 1/16 to 1/8 quart of oil (10w/30). I do not see any leak around the engine nor on my garage floor. I do not see any white smoke out of the muffler. At 200,000 miles, piston rings and valve stem oil seals are a little bit worn out, and the top portion of the cylinder bore got a little groove already. All these causes a little oil burning inside the combustion chamber. Now, I add an oil additive ($2 STP) that thickens the oil (every 3000 mile oil change). Also, every 6,000 miles, I also add an oil additive ($6 Bardahl, not sure of the name brand) that coats/fills up scratches in the piston cylinder. It does not stop the oil consumption but it lessens it. It helps.
By the way, I own a 94 Toyota Tercel before with more than 230,000 miles. Same problem.
This is only my actual experience.
