The 767-200ER was the first extended-range model and entered service with [[El Al]] in 1984.<ref name=Boe_767_back/> The type's increased range is due to extra fuel capacity and higher maximum takeoff weight (MTOW) of up to {{cvt|395000|lb|sigfig=3}}.<ref name=no163/><ref name=762specs/> The additional fuel capacity is accomplished by using the center tank's dry dock to carry fuel. The non-ER variant's center tank is what is called ''cheek tanks''; two interconnected halves in each wing root with a dry dock in between. The center tank is also used on the -300ER and -400ER variants.<ref>{{cite book |url=https://www.worldcat.org/oclc/647811907 |title=Aircraft fuel systems |date=2008 |publisher=Wiley |author=Langton, Roy |isbn=978-0-470-05947-0 |location=Chichester, West Sussex, UK |oclc=647811907}}</ref>{{Rp|35}}
