Therefore at 700ppm zinc and 600ppm Phosphorus, Comma classic is probably OK? or have I missed something here?

Hello Richard,

Ideally you don't want the Phosphorus level to fall below 800ppm. If it were me I would not use the Comma Classic.

well I drained out the halfords classic+wynns and filled up with comma europa 15w50 today which has more than the minimum zinc and phos in it.

I feel a lot better- hard on the wallet though as the other oil had only done 300 miles :roll:

still a good flush I reckon lol
