Oil Question

[TriumphTT900]

Hey guys the weather is getting warmer and its time for an oil change. My bikes recommended oil all season is 4 liters of 10w40. I have 4 liters of 5w30 in the garage and was wondering if that would be alright? I can just go up to the store to get the 10w40, but for the sake of my tight wallet i'm considering this 5w30.

Thoughts?

If you have very high temperatures in the summer, and ride in city traffic, go for the 10w40. Otherwise, you should be ok with the 5w30.

It's only a few bucks, buy the right stuff and be done with it.
