as I am about to change the clutch on dear Cally, I want to be 100% certain as to which kinds of oils to use. Please let me know what you think! Any help is appreciated - at the very least, join the fun and add to the confusion...!
TXB: NotNormal suggested SHC 75W/90 and that´s when I started wondering....
I thought the TXB used some kind of special oil with limited slip
properties. Andy Kirwan´s how2 specifies "Vauxhall synthetic 90 443 530" but of course I don´t know the specs of this oil...? Any suggestions?
As for the F28 gearbox - NotNormal suggested a straight SAE80. Well in that case, would any kind of good old mineral-based SAE80 be best? Can´t I use Mobilube1 SHC 75W/90? - or will that damage the gearbox or cause other kinds of unexpected problems?
The PAS oil seems pretty much straight forward, Dextron III - everyone seems to agree on that. Is Dextron III synthetic? I remember something about the first Turbo´s running on mineral-based PAS oil until it was changed to a synthetic oil which supposedly lasts longer?
