Yea, the price is right for synthetic.
I have to order from WM dot com. Free pickup.
I didn't change the oil, just took the sample after about a quart had drained. Used to run Delo 5w-40. So that's what I had on hand to top it off. Not really a fan of mixing, but I'm sure it will be fine.
I'll run this mix to my regular 5k OCI, then full Havoline DS pro again.
