My ride's a Corolla '94 Gli A/T. Just had an oil change yesterday as well as ATF change. I usual have both changed every 5T km. For the engine oil, I use Mobil 1 Synthetic 20W50, that's about P450 per liter. For the ATF, Castrol Dexron III P125 per liter and about 4 1/2 liters. Be sure to check your transmission filter as well especially if it's been a long time since you had yours changed. Check it and have it replaced just like you do when you get an engine oil change.
