2005 Mazda 6 V6 3.0-liter has an oil capacity of 6.0 US qt. (5.7L) with oil filter change.
Introduced in 2003, the Mazda 6 was created to replace the aging 626 and Millenia fleets. Its sporty and unique design with plenty of features and options made it an instant hit. It was powered by a 3.0-liter V6 engine that was rated at 220 horsepower.
In 2004, Mazda introduced a new hatchback and wagon style in midyear. Minor changes were made to trims and option packages. A six-speed transmission was now available for various models, too. New front and rear fascias graced the 2006 Mazda 6, alongside of a new grille and side sills.
Emissions were reduced in the V6 engine models, which reduced horsepower to 215. Traction control and ABS were now included as standard features on various trims, along with side impact and side curtain airbags. In 2007, Mazda made changes to different trim levels to better accommodate buyers. The car would pass through 2008 relatively unchanged.
In 2009, a redesigned Mazda six was introduced with a more modern style and new technology features. The only notable change for 2010 was the addition of optional Bluetooth integration. Headlights and foglights were updated for 2011, and new side mirrors were introduced for various trim levels. The Mazda 6 zipped through 2012 and 2013 relatively unchanged, except for the new 18 wheels option for higher end trims. In 2014, Mazda released a completely redesigned version of this popular sedan.
