Has anyone experience with Castrol XL 20W - 50 from their Classic Oils range?

It is described as:

"For pre-1980 modern classic cars

A conventional multigrade engine oil of good all round performance, formulated with high quality mineral oils plus selected additives, ideally suited to older technology and classic car engines.

Offers excellent oil consumption and a very high level of engine wear protection."

www.castrol.com/uk/classics

I am wondering whether to use it in my 1973 911E, which is currently on Castrol GTX 10W -40 and weeps a little.

PS. For some reason I come up as a non-member when I post. I am a member, honest!
 
can't answer your question about oil, as i use Shell Helix 14w 40 in my 1969 911t.

OK, I'll do that, although I did fill in all that info when I registered on the Forum.

yes i know. but this system is not able to check your membership automatically so it has to be done manually. [:mad:]
 
I have a friend who's a professional engine builder. For older engines, he swears by (and has converted me to using) Valvoline Racing oil (it's 20-50), ca. £20/5l.
 
That's interesting. I seem to recall using Castrol XL in me 3.8 Jag back in the sixties.Perhaps Castrol are pushing it again.

Thanks for the opinions.

The original drivers manual says SAE 30 in summer, SAE 20 in winter down to -15 degC (SAE 10 below that). So a 20/50 multigrade should cover both summer & winter.

The man at Castrol said that he knows of people using their XL30 monograde in early 911 engines, because that is as close as they offer to what was originally specified. He agreed that the thinner the oil, the more likely that the engine will weep a little oil when standing.

I prefer to use a multigrade, so I think I'll try the XL20w-50.

The builder of my Appendix K racing Lotus twincam motors swears by the Valvoline and so I use it in my Bonneville Sprite as well. But the genius who built my 1650 pre-crossflow put Motul 5-40 synthetic in it, so that's what I use with no problems or stains on the floor. Francis Tuthill tells me to use Millers 10-60 fully synthetic in the 2.7 and I use whatever the Peugeot service people put in the 3 litre 406 - which at 125,000 miles uses the least amount of oil of all, including the Cayman S (2000 miles per litre[:eek:]) and Jane's 120D bimmer.
I use extra virgin oil in my salads and I'm pleased to report that I get no leaks at all from that.
 
Andy Prill from Maxted-Page & Prill recommends Motul 'Classic Oil' (20W50). They have some pretty serious cars, so I guess it must perform well.

I ordered some direct from Castrol Classic oils, and they delivered in 2 days. Will change the oil later this month.
