What type of gas to put in a 1999 Chrysler 300 lhs?

The 1999 Chrysler 300M (note: there was no 300 LHS in 1999; the LHS was a separate model) likely requires unleaded regular gasoline. However, always check the owner's manual for the specific fuel recommendation from the manufacturer. The sticker inside the fuel filler door may also list the recommended fuel type.
