Just use it up in a car or something,or use it in the bike until you run out.
You can mix it with any oil out there. It doesn't have to be royal purple.
If you think it's too thin use 1 quart up in every oil change,mixed with the rotella. Don't over think this. You can use it until you run out,then just re-stock with thicker stuff. Or you can save it for top ups,or use in another vehicle that specifies a 30 grade. The options are endless.
Or you can trade me or some rotella if you like. I'll even add a quart extra. Pm me if you want to.
