Possibly, and how about a link in there for Wappings oil thread in the font. If you search for oil it doesn't appear in the results ( i assume because there's been no replies on the thread ).
Why are some people so obsessed with this silly question?
These bikes hold a lot of oil.
If it is low, it is probably close to a service, so it doesn't matter.
If you are demented enough to wish to top it up, any oil is better than no oil, even if it is not to the bike manufacturer's spec.
Remembering the dilution ratio, this probably won't matter anyway, especially since it probably is close to service.
When changing the oil myself, (yes, some owners know how to, and are not prepared to be stitched by a dealer for doing so), I just go into a local motor factor & purchase 5 litres of any fully synthetic. Don't even look at the spec, because I wouldn't know what it meant anyway, and am not prepared to waste brain cells finding out.

A wet clutch is not the only reason to use bike oil, with a dry clutch other reasons to use a bike oil still exist:-
Bike engines rev higher and pistons/cylinders get much hotter than in car engines - this is especially relevant to aircooled engines: car oils could evaporate from bike's hot metal surfaces leaving them unprotected.
To cope with high speed moving parts bike oils have a much greater shear stability than car oils.
Car engines have larger sumps so car oil has a lot less work to do than a bike oil.
Bike oil is developed in expensive laboratories by people with tall foreheads, consider before sticking Halford's car oil in your engine.

Sorry but none of this applies to the boxer engine!
FWIW I top up using some cheap but good quality 15w50 bought from my local car parts shop.



For what it's worth, in Wapping's post, the guy from Castrol says: "he's heard good things about Castrol High mileage GTX" in GS's.
I also have an email from Redline oils recommending their 20w50 car oil and "not to waste my money" on bike oil for a boxer engine!!
Sorry Proff, bored in my office today!!![]()
