Can I add Xylol (Xylene) to boost octane?

Yes, you can. You’ve discovered the secret to boosting octane. You sly bastard! The government will soon be sending someone to pick you up. You will likely be tortured at Gitmo, or perhaps somewhere in the middle east. Egypt?

Sorry, we don’t torture. My mistake.

Be that as it may. If the government doesn’t pick you up the oil companies will, and they’re WORSE. I’m glad I’m not you, oblivion. I wish you the best of luck. I suggest running NOW, before they get your location.

Too late, they already have it.

You have opened a very dangerous can of worms. They will be looking for you. They will find you. You can’t hide. You have exposed the Xylol (Xylene) conspiracy. God help you.
