Why you should stick to the 85w90 oil spec Guzzi chose

[Huzo]

If it’s just to foster discussion or improve one’s knowlege then there’s no reason not to have a current oil thread running….
But.
Why would changing something that’s been successful for as long as you’ve ridden, even warrant a second thought ?
You might as well have a thread on new and interesting ways to wipe your ass…..
If you can still bight your fingernails and not dry reach, you’re doing it right…Don’t change a thing…
