The price of changing engine oil and ATF won't differ much among garages. Only plus or minus 2 to 3 dollars.
If you car is BMW, or Accura which needs special engine oil, you have to go back to dealer.
Corolla is a very reliable car, and many driving instructors use this to teach students. Your engine, if you change engine every 5000 km or 6 months whichever comes first, can last 400,000 km without problem.
