It was a dealer service but a bit of complex stuff. Would have been easy to forget filter. I invoice says Castrol EX Magpro DX 5w-30. Was a clear. typical Castrol oil, very thin as all 5w/30 are. I hate them . This country needs a 40 grade. I have never been guilty of putting a 30 grade oil in anything. Bad enough on a cool, day, but on 35 to 40 deg day it turns to water. You can hear the difference in the engine noise. They have a dealer oil with a descripton close to that but don't know what the EX bit is. They seemed like good blokes there. so I hope they got right. They were doing about 3 jobs at once.
