Sales sheet says longer duration and a stronger spark and operate cooler than the Lucas equivalent.

Fuchs Silkolene SAE20 fork oil. Mail order (Hitchcocks). I can get 15w locally, if it's too harsh.
Going to have to find a better way to lift the bike. My current bike jack needs to go under both frame rails and won't go past the centre and the sidestand. Ended up raising it with a trolley jack under the front cross rail, with the centrestand down, but didn't feel very secure.
Needed doing. The old oil looked like gravy.

Silkolene SAE 20 should be ok. I used that before I fitted the Lansdowne dampers.
Although 10W/30 etc. is listed in the lubrication section of the workshop manual, it does say SAE 20 in section G8.

SAE is used as a standardized motor oil grading system. Thus, a 20w in one brand of oil has similar viscosity characteristics to another.
There is no standardized system for fork.oils. One brands 10w may be similar to another's 20w and yet anothers 7.5w.
This is a good read and has comparison tests of a great many fork oils by brand and weight. Comstock-worthy work.

SF seems to refer to an updated oil specification rather than a change of viscosity.

I think that is mislabeled on the shop site.SF seems to refer to an updated oil specification rather than a change of viscosity.
FORK OIL SAE 20, 1 LITRE, SILKOLENE (SF 20)

Silkolene fork oils don't appear to be SAE rated.

SF20 still appears to be an 'SAE 20' viscosity fork oil.

"Description:
Silkolene SF 20 Monograde Fork & Suspension Fluid
Silkolene SF 20 is a monograde SAE 20 fork and suspension fluid featuring a high VI index formulation. It combats friction, protects seals, resists corrosion and ensures smooth suspension under all road and competition conditions. Grades can be mixed.Silkolene's SF range are based on highly refined base oils and advance performance additives to provide optimum damping and consistent smooth fork action for road going machines and those requiring heavier base oils."

This is from a web store.
The screenshot I posted above was from the manufacturers catalog and.they don't mention it anywhere being SAE 20.
ISO 68 correlates with SAE 20, but it isn't SAE20
QUESTION FOUR: IS FORK OIL MEASURED BY THE SAE SCALE?
No. Fork oil weights are derived from the industrial standards used for hydraulic applications, called the Saybolt Seconds Universal (SSU). This measurement uses a similar viscometer arrangement as used to determine a cSt value, but grades the oil using a much more sensitive viscosity calibration scale.
QUESTION SEVEN: WHY DOES MY FORK OIL HAVE A WEIGHT?
Consumers like to shop for oil by weight. So, the motorcycle industry took the SSU/VI measurement and converted it to weights based on the same scale used by the SAE. But since the SAE weight schedule is so widely incremented, two cans of fork oil with different SSU viscosities of 80 and 100 can both be listed as a 5 weight (5wt). Yes, it is confusing!
I know that I am being pedantic.

Front Fork Oil
Hello everyone, Can someone please tell me the proper oil to use in the front forks. Springs are stock. The "classic motorcycle guy" at Autozone sold me some Roayl Purple 10W-30 fully synthetic. The Norton manual is not very specific, but from what I can gather a 10W-30 or 10W-40 would be...

If Silkolene SF20 is not the approximate equivalent to the previous Silkolene 'SAE 20' fork oil (the containers are marked SAExx) then the question should be "What is?".

Happy new year fellow Norton enthusiasts!
I'm sold on this Fuchs 20. I'd like to try it. Any idea where you can get this stuff here in the USA?
