I use Halfords 5W/40 fully synthetic oil in my car (dont know if its the same as the motorsport oil) and it meets the specifications of Mercedes 229.3, VW 502.00/505.00, Porsche and BMW Longlife.
 
that was the oil i was using for a while phil when i was having it for free as i worked there, did the job..... gone to the synta gold now as i got that cheaper than the halfords stuff!!
 
im used to being called rhys now any way. Lol. Always get called it on here and everywhere else. Im sure that on the back of the ones we can use they are approved by Vw/audi but it doesn't say vag though.
 
I used to use it in my old car, then changed to millers 5w40 comp oil and it transformed the engine. Ive always used millers since. Currently using 10w40 comp.
 
Right, bringing this back up.

Is anyone running the Mobil 1 motorsport stuff, the 15w50 one?

I've been using the halfords 5w50 and want to go for a better grade of oil due to me doing more track days etc next year.
