Comma is good as far as I'm concerned, used it in my club race car:D
 
hi data, coming from you or wammers i would say the service and the offer of free oil is a go for the weekend then, thanks.
 
As long as you change it regularly (do mine every 5k miles) and the viscosity is correct you'll be fine. Most of the synthetic ones are so they only need servicing every 20k miles or some other silly number. Even then I don't think it works as well.

nearly any decent oil is okay including comma, change often is the factor, remember the prob grease, consider some lucas in the tranny service :):):)
 
thanks for the info fellas, im going to service both axels as well, there very quiet, but do i need to flush the diffs, or do you flush the diffs?, maybe ill just change oils because they do run without fault, thanks.
 
The Rover V8 is a old engine design - anything remotely the right spec will be fine.

No point flushing diffs unless there's crud in the old oil - in which case the diff is probably on the way out anyway.

Change all fluids often and you may be rewarded :):):)

I use fully synthetic 10/40 in mine and usually change every 10 000 miles as when im using the RR i do high mileages in a short time and some places I cant get the oil changed like in the Gobi desert Mongolia.
I am just changing my timing chains and there is no sludge in the sump and it is remarkably clean for a diesel thats done 175000 miles.
