Regular unleaded gasoline is recommended but the octane is 85 many places but 87 in the manual.
Example, Denver Colorado and other cities and areas, 87 octane is the baseline and 89 and 91 are the more premiums. Is 85 octane suitable for the 2014 Tacoma or is the midgrade or premium required?
http://www.toyota.com/t3Portal/document/om/OM35A38U/pdf/sec_8-3.pdf ...Page 600 .... Use 87octane. 89 or 91 is acceptable but not necessary, you will get the same economy and performance with a all octanes, but 85 has a lower ignition temperature and may pre-detonate. Avoid any fuel with more than 10% ethanol
