Re: is this oil ok?
There are cheap oil guys and quality oil guys.
I'm a quality motor oil guy.
For the money I spend fueling my motorbicycle, it may as well be the best oil money can buy.
If for some reason, your oil mix is too weak, at least the better quality stuff will still somewhat protect you better from catastrophic failure.
I love my Motor Bicycle, I love Beer, I'll try not to like them both at once.
