  3. Change interval on my car is 9,000 miles or one year. I use fully synthetic oil and quality filter changing the oil once per year. The cars has done 175,000 miles. The oil level drops half way down the dipstick before changing. So not burning excessive oil at all. I bought the car new and use fully synthetic oil from new.
