I know there's a thousand threads on the net regarding this, but here we go...

Up here in Europe, they don't sell any of the v-twin oils ( at least not where I live ). They don't sell Redline, Bell R. etc.

If they sold it over here, I would put the Mobil1 V-twin in all three holes. But since they don't, would the Mobil Racing 4T 15w-50 work?

And keep in mind that it's cold up here ( all summer ). I could order oil online, but they sell the 15w-50 on all gass stations, so it would be more practical.

Thanks.

 

Since Amsoil is/was a mail-order company, can you get that shipped at a reasonable rate?
I am no expert, but I don't see the harm in the 15w-50.

 

If you use Mobil1 products, as I do, then:
The Mobil1 V-Twin 20w50 is of the engine, ie oil tank.
Use Mobil1 4T-10w40 should be used in your primary
And Mobil1 75/90 gear oil in the transmission.

the 15w50 won't hurt in the colder seasons, but we get some warm summer days here so I go for the 20w50.
