229.31 vs 229.51
Hello Chaps
I have just done a service on the crd WH.
After filling, I find that the Valvoline MST is now not 229.31 certified.
But it is 229.51. Everything I read tells me that 229.51 replaced 229.31 and that it is now basically obsolete in the MB world....
Anyone confirm?
Cheers,
Dave
