I run castrol rs 10/60 in mine, but was just wondering if mobil 15/50 is okey to mix with? and is equally as good as 10/60 ?

 

thanks people

 

Jim.

IMHO, yes you're fine to mix it..

 

And IMHO, yes it's as good.. Ok so that's not a scientific evaluation, but I ran it in my last car, and in my 5 GT Turbo before that, and I ran the 0W40 in my 19 16v before that, and they all loved it..

 

The 0W40 is a little thin for most Z's, because of their age - although I believe either H Le Hir or Eric Lymon run it in their Z (sorry guys, don't mean to lump you together, but all I can remember is that it was a non-UK owner who's tech advice I actually trust, and that narrows it down to one of you!), and have done since new, and it's fine..

 

Aanyway, enough rambling.
