Either is ok, depending on temperature and wear in your engine from mileage.  I've got 15W40 in mine, no probems.

I would suggest that you do a search for Oil on the forum and read the hundreds of opinions already expressed and find one that fits you. You have a valid question, it is an explosive topic around here.

Isnt there a short movie about Honda's where they put used vegetable oil in a Honda Cub and drive it all over before driving it off a building and it still started?  ;D

Yep, the program is called the Ten Greatest Ever Motorcycles and is shown on Discovery every now and then. Number one is the Honda Super Cub.
It's in fact the world's most manufactured automotive vehicle. Can't wait to see it's electric follower.

Lol.. Yup that is the one. Personally I just use Penzoil 10W-40. Altho I just saw Hondaman's CB550 tips and he lists some very specific oil so next change I will use what he listed.

Great video.. love that one!

Oil ...synthetic or non synthetic?




I like air popped corn with sea salt and non synthetic butter flavoring.

Why is it that every time I go to buy oil, I start to think about popcorn?  I'm getting sick of popcorn.  :D

I like Synthetic my self but everyone always recommends regular oil so I just use mobil one in my blazer.

I like corn popped in really fatty oils. I like to feel my arteries close as I eat the stuff. And lots of morton salt!
