No problems at all. I'm the type of guy that doesn't tip as a general rule but if I'm suitably impressed, I'm all over it
Oil wise, he said he's always used Penrite and swore by it. Really had nothing nice to say about Castrol though . . . . only BMW's official oil because they sponsored the F1 team etc. Some of the major Sydney BMW dealerships are switching away from it apparently . . .
I'll be very interested to see what my fuel economy is like with new oil and new air filter also. There was really grotty aftermarket one in there that couldn't be helping the air flow much . . .
