The specialist I use, uses 'premium fully synthetic 5w40.' My car is a 98 Brooklands 'R' so should be the same.

Personnally in my Contiental R 1997, with air/water Turbo, I use Castrol Edge full synthetic 10W60.
I think 5W... is a little fluid at cold for those old engine, ...w40...is fine at hot. for regular engine. For Turbo ... w60 is better when engine is hot.

This question always gets a multitude of different answers. The most common recommendation I have encountered is a good quality semi-synthetic 10w-40

Mike,

This is a cat-friendly zddp additive:

Thanks for all your answers. Don't know what I would do without you guys.
So I could use fully synthetic 10/40 oil with Camguard.
Can camguard be purchased in the UK?

That's exactly what I would suggest.
10W40 full synthetic .

One point, if your car has a high mileage and had never full synthetic oil, it's not a good idea.
Because of the solvant which will clean the engine inside but may stroke too.

So depending on this, with a low mileag and an engine with half synthetic you could go for full synthetic, watching your oil pressure ( not too high at iddling hot) and drain again in one year to change filter with probably mud.

If the engine always had mineral oil and has a high mileage ( more than 50.000 km/miles) , go slowly.
First put 10W40 half synthetic, in one year drain and put the same and in 2 or 3 years, you could go to full synthetic, but drain every year to avoid any stroke from mud cleaned by the solvant in oil.

Hope you undertand the essence of my thoughts through my modest english.

10/40 semi or full as Jean ran through.

You need to make sure your engine is running hot enough to get fully synthetics to work properly. IMHO pre efi cars often don't when poodling about and pre 90s rarely do here in the UK. .

Jean your English is brilliant and better than my French will ever be (as shown by a recent rescue mission to Monaco - thankfully I got by with enough for food and drink ordering and then just pointing at the technical bit's ; D )
. . .
use sludge for mud. . . . Although I have worked on a few which looked like mud

I'm not sure what word you are looking for with stroke though. Smoke? Glazing?

Cheers, Paul.
