Real world experience,

, it's a posh Tractor

(The single cam units are proper tractors

)
My hexhead suffered from being filled with the more popular viscosity oil and boy, do they not like that in the hot summer !!
I thought it had dropped a big end... One oil & filter change to the other viscosity & a new genuine filter and it sounded like a Swiss watch - Panic over
They also use oil, I rode it back from Scotland with low oil - It was in the middle of the sight glass when i last checked it , and not visible when i got back ...
It takes about a quarter of a litre to bring it up from the bottom to the the mid point on the sight glass ,
Given there are about another 3 and a half litres of oil in the system , your not exactly in any danger
Coming back to my TC from the LC, i forgot that the Hexheads use oil, and i normally check, the oil level once a week, using the kombi function
It says Oil OK - but the sight glass shows oil right at the bottom ... a quarter of a litre is all it takes to bring it up to the mid point
(i was going to top it up to the top, but it's going in for a service in under a month , so it would have been a waste !)
They use about half a litre give or take between services, so it may have been on the lower end level wise, and they dont loose much when you drop the cam covers
Looking at the repair instructions, there is a requirement to check all fluids are at there correct levels ??
Given that the oil level can be anywhere between max and min it could be argued that it was at the correct level when checked
(The manual does say that oil temp can affect the level , and should be checked only after a long trip & with the engine at the correct temp ie hot)
8 miles ... long trip ???? i'd have been out onto the A27 asap and started scrubbing the tyres in

Either way, its not the end of the world, just top it up and ride it

Do yourself a favour and start your own Sticky thread - Hexheads are shite because -
That way you can troll all you like, and everyone who agrees with you can add comments in there !
i dont think in the time ive been here , you've posted one positive thread about the marque
Seriously ? why bother,
People ask for advice , and all you do is moan
You dont even offer any balance
??
