AoA, Respected members,I am using 5w-40 shell ultra in my corolla 2007, 81000 km driven, before this engine oil i was using caltex 5w-40. I have noticed that there is slightly oil leakage, altough after 500 km of the oil change, there is no sign of oil reduction on dipstick. The other problem is engine noise has been increased slightly.
