I had been using the Castrol TWS 10W-60 Motorsport (and its successors Castrol EDGE 10W-60 Professional and Castrol EDGE 10W-60 FST) for more than 10 years without any (noticeable) problems. For my last oil change the Castrol was not available and as I had read in different threads that it is anyway not the best oil (although it is the recommended one by BMW), I decided to get a new one. I was recommended the Motul 300V 20W60 or the Motul 300V 15W50 and saw that people online were using and having good results with those. I went for the 20W60 and I've had it for a couple of months now.
Last week I got smoke from the car. I stopped and saw that there was oil all over the engine. The car was brought to the garage and they told me that a high pressure line (not sure which part it is) was the problem. I still haven't got the car back but I started thinking if the thicker oil could have caused that. Or is it just the ageing of the car (it's now 15.5 years old)? What do you guys think?
