I can't help it. I have to say something. Too many uniformed tools posting nonsense. So easy to be an armchair warrior.
If we don't buy Russia's oil, someone else will. It's fungible. Not buying it will drive up the price. What's needed is for everyone to not buy their oil and be prepared to open more reserves, produce more, and be prepared to still pay more. The price will not come down anytime in the near future. Get a life and stop practicing folk economics. Let the experts sort it out.
For those interested in the nuts and bolts, here's some good reading on the logistics of the situation as it's playing out. A proper understanding can help one see the bigger picture. Russia can only go so far, logistically. To make up for it, they're going to get really ugly.
All the best,
