So I was running short on time for an oil change and today was my only available day. It's raining so I had to go to an oil change place. I asked them to fill my sample bottle when they drained it and they only filled it halfway. :/
I am not sure if this is enough to send to Blackstone still. They said they need between 2.5-3 oz. to do all their tests. I don't know what half a sample bottle (the clear one w/ black lid) is equal to in ounces.
Anyone ever send half a bottle?
