"All Mini dealer Service Departments are all connected to each other. "
Yikes ...I am a part of a Cult that I did not know about
I do wonder sometimes if the the cheaper oils are really as bad as they make them out to be. Now they use recycled oil to make it new again. What is great. I always worried about the 1st oil change when I buy a new car. I change the oil after about 500 to 800 Miles just for a piece of mind and to flush out whatever is in the motor no matter if the dealer says it does not need it. I bet it is an old wifes tail by now too. I guess we old farts don,t trust anybody... when they say trust me it does not need it.
I get the feeling some on here think i put cheap oil in teh car-far from it; i did a lot of research and the petronus is good synth stuff mini approved -covers every spec and states quite clearly on the can it is for mini. it was a bargain, yes-normally sells for much more but i was lucky!
Anyway this is a subject close to my heart;
if you look on nam there are some great articles on oil and analysis-re quality-and a real big one found that there was no real advantage in changing the oil after running in since there was very little evidence of engine wear =ie the engine is made well to close tolerances unlike the olden days. HOWEVER nothing to lose for peace of mind as you say!
Likewise another report analysed a variety of oils-the findings were VERY interesting-the Castrol mini recomended when i bought mine came out quite poorly-more additives to extend the service interval of the oil rather than anti wear properties-amsoil came out really well for you guys in the usa, and for europe mobil 1 was better but best from memory was motul which came out really well. not sure where i found it but it was really interesting and a good read. lots of chemical analysis etc to back up the findings. i suspect that mini do the same withoil as with tyres-do a deal with a major manufacturer for factory fill-they get it very cheaply and then stamp mini recommmends-on everything. that way we the punter go out and buy the product at full price-happens with tyres too! competition for std fit tyres is very high apparently as most people just refit what's on! Am i being too cynical here?
i concluded that if you are changing the oil regularly then there are better oils out there than the factory fit castrol BUT you dont want to risk the warranty!BUT again if you read the manual a variety of oils and viscocities will do-it says so in the book! it's all good fun!
