No. The manual for the Beetle Type I's indicate that it will run on regular unleaded fuel. 2. This is not required, but you might add a little(about a quarter cup) of Marvel Mystery oil to the gas and engine oil. Helps to lube the engine valves. But don't use to much at a time...

The advantages of using premium unleaded gasoline compared to regular unleaded gasoline is its increased efficiency and higher burn rate. It is designed to work in higher combustion engines and will often produce poor performance in vehicles designed for regular gas.
maybe, should be using a Lead substitute additive to prevent trouble.

It's the gasoline using the additives containing lead to improve the octane number.
Bromine is a halogen element. It is used as a gasoline additive (many brands are using his anti-engine knocking agents for their gasoline). Also, it is used for pesticide, the bromine makes a tenting method so it is perfect for fumigate housing.
BMW recommends using Premium Unleaded Gasoline with a minimum octane rating of RON 95 (equivalent to AKI 91 in the US)
