Hi folks, apologies in advance for probably quite a dumb question, but I need to top up the oil on my E46. I've never had to do it (it's a couple of thousand miles from it's next service), any idea what kind of oil I need to put in there? Would it be synthetic?
Just gone through 55k miles and it's about 18k from the last service (still getting used to massive service intervals). I'll go with the synthetic stuff I guess if it's ok to mix it.
