There are number of different kinds of gas you should use. The gas you should use depends on the situation.

pavarin
should we use natural gas and oil
You should use propane gas for your BBQ grill.
Roxy or RaveGirl
The type that mount on the exterior spare tire are the best. The brandname of mine is Rhode Gear.
Ulcerkit
Nope, it is a painkiller (US brandname Tylenol).
Regular gas should be fine
"Brandname" advertisements "is" ways of marketing a brand name product such as Zoo York or Nike. They can be commercials on TV or the radio. They can also be things like billboards. Anything that shows off the product.
Use what the manual tells you....regular gas.
