There are probably as many different opinions on that subject as there are triumph owners !
The one thing that most owners agree on is the necessity of an oil formula that addresses the valve seats and lifters.
There used to be a zinc phosphate (sort of) additive in oils that is missing in most of todays oils. Modern automobile engines
don't need it. It's called ZDDP & its purpose was to coat the combustion chamber and other moving parts to help
prevent excessive wear. That's over-simplifying it but you get the idea..
So, you can buy ZDDP additive & add it to your modern oil formula or you can purchase specially formulated ZDDP oils
specifically for our cars. The big 3 sells both. It used to be that Valvoline VR1™ racing oil (only) had enough ZDDP
in it to be satisfactory for our cars. Weather they still produce with ZDDP I don't know. As for what weight,
detergent vs. non-detergent is the area on which everyone has their own opinion. I live in So. California where it never
gets below freezing but often reaches triple digits. I have over 50K miles on my 87mm rebuild with hard seats and lifters.
I run a mild cam but seldom go over 4000RPM. I still have factory spec compression on all cylinders. All of those things
determine what weight oil I use. (20w-50)

In reply to # 1210203 by 6TTR3A Weather they still produce with ZDDP I don't know.
They do. There are actually three different Valvoline racing oils now, the "NSL" (Not Street Legal) stuff, VR1 and VR1 synthetic. All have plenty of ZDDP. I use VR1 in 20W50; but like Frank I live where it gets hot but not cold. 10W40 might be more appropriate for CT, especially if you drive in cooler weather. Keep an eye on your hot oil pressure though, and step up if it drops below 20 psi at idle.

Watch for the sales; both O'Reillys & Autozone have VR1 on sale at least once or twice a year for about half the usual price.

Just a footnote here. The Roadster Factory has Brad Penn motor oil formulated for older cars. It is on sale right now where you buy 5qts. and get the sixth free. Might be worth it if you have other parts to order. It is made in the old Kendall refinery in PA.

You would know that,Dave. I heard they used to make some other brand of old oil there too. Something like Amalie Pro ?

Following this string, does anyone know of a source in the US for Castrol Classic XL 20W-50. Used it years ago and could buy it at most any autoparts store, but now only seems to be available in England.

There is a good article in this sites library, with information from someone who knows what he is talking about.
