It is said that this is made for Halfords by Comma oils Duckhams is owned by BP
however the Halfords branded product seems to tick the boxes and its price means you can change it regularly which with our long winters is a good thing
You can also get it cheaper with a Halfords trade card not too hard for quite a lot of us perhaps
From a Halfords website:
"You can apply to become a Trade Card member at any Halfords store. Simply ask a member of staff to help you complete your application and bring with you your proof of working in the motor trade - outlined below:

After a lot of thought, i am going to go for 20/50. This is due to the fact i don't know the bike yet, and a thinner oil may be better for the winter etc, but may also induce oil leakage/burning etc.

Its now a matter of which one!!!

Ask 20 Vincent owners about oil choice and you will get at least 25 different answers.
I have used Morris classic 20/50 for years without any problems.
Remember, any oil is better than no oil, and if you change your oil regular then that's good as well.

If you have good cams etc, Most oil will do, Maybe Not the latest Syn' !.
It's just that I remember running 20/50 in my much thrashed Goldstar 350cc, Trying to keep up with Vin' Twins,
And the oil turned to water, In a very short time.Cheers Bill.

Oil turning to water happened on a hot spring day at Montlhery in '52 not a lot anyone could do about it the Oil suppliers were a main sponsor!

It was so bad, I used to just suck the oil out of the tank and renew, Often !.
In the end I broke the T/side main shaft, A weak spot I am told on these bikes,
I was last seen thumbing a lift 90 miles down the A1 !!.
Cheers Bill.

Sustained running at high speed over several hours using a crowded roller big-end rather than a caged roller was probably the major factor.
