Mobil has a worldwide presence, & you should be able to find Mobil 1
synthetic oils. I use Mobil 1 15w-50, and have for over 9 years & over 37,000 miles in the same engine. There has been no measurable wear over that time & mileage span. No leaks either.
Engine not raced, but sees hard use from extended high rpm and supercharger.
