what is the best 5w40 oil to use on a racing vr6

[Tobias Rideout]

hello, what is the best engine oil to use on a vr6 that goes to the track and gets hammered a lot?

[insanitybeard]

Probably Mobil 1! I don't know how well the autoboxes will take being hammered, just sayin'.........

[Tobias Rideout]

OK thanks m8, are autoboxes not good for racing?

[insanitybeard]

No personal experience but the autoboxes fitted to these vehicles can be prone to issues especially after higher mileages and if they're being hammered I don't know how well they'll stand up to it, if you do a lot of racing starts I can see the clutch packs burning out for one thing!

In any case, photos or it didn't happen.

do you mean the vr6 gearbox or the 2.3 ford, because I think the vr6 gearbox is a vw one? thanks T

[insanitybeard]

The AG5 auto gearbox (as used with the 2.8 V6 and 1.9 TDI) as I think it was called by VW/Ford was not actually made by either company, it's a Jatco box, see here.

ok, thanks, looks complicated! I was steaming down the only duel carriageway on the island yesterday, all quarter mile of it! I think before the engine got to full op temp. and I heard a loud hissing noise! do you know what this could be? many thanks T
