FULLY SYNTHETIC 5W-40
i would NOT use Mobil 1 Motorsport in a Cup !.........its a bit thick for it, its a new car !
change it to the 0W-40 Mobil 1, and id bet you notice a power increase
if its just a top up mate then use Mobil 1 0W-40 / Total Quartz 9000 5W-40 / Shell Helix Ultra 5W-40
all of those are fully synthetic
