what oil for a griff 4.3 and...

[mhardy]

What do you use in yours????

At a cold start you can hear the hydraulic tappets knocking hardly, after seconds it disapears slowly. should we try a engine flush additive and then change oil?? or.......


thanks,

I now run Valvoline Maxpower 10W/40 Semi Synthetic. Oil pressure up! consumption down!
Used to run Mobil OW/40.

Castrol RS 5W - 40.

Expensive but excellent.

No point skimping on this, it is rather important

You can get this in halfords

Matthijs, come on, you know better than this: Castrol RS 10W60 is the ONLY oil for the Griff/RV8.
If there is a tapping noise, it can be the rockers need replacing. Worse case, it's the camshaft and/or pushrods.

see you, Gerjo

I'm assumming here that mainland Europe's Castrol RS is rated differently to GB Castrol RS.

Or am I missing something :/

I use Valvoline Racing Oil, as recommended by V8 Noel. The logic is that the old Buick V8 was designed back in the days when 20/50 was the norm and modern 15/40 or 0/40 is a little thin. My oil consumption is very low.

I can only agree with Gerjo, Castrol RS 10W60 is THE oil to use for the Rover V8.

PS yes the mainland European version

See this thread. Loads of good info.

Mobil 1 motorsport.

[barbon]

Valvoline Racing oil is the one

[david beer]

Castrol GTX

hmmmm, a nice definitive answer then. I'm sure that finding the perfect oil is the motoring equivalent of finding the holy grail.....

Castrol RS 10W60 ... indeed .

Changed oil 45min ago and sound good.

Thanks guys,
