For the 2005 model year, Chrysler recommends that Crossfire owners use engine oil with a 0W-40 viscosity grade. The company further recommends that owners use oil that meets Daimler's MB 229.3 or 229.5 specifications, such as Mobil 1 oil. Chrysler recommends a Mopar 5102905AA oil filter.
Chrysler recommends the same filter and oil for the higher-performance, 2005 Crossfire SRT-6. On its website, Daimler, Chrysler's partner in 2005, provides a list of specific oils and brands that meet its specifications. Companies such as Castrol, Chevron, Gulf, Lukoil and Shell all make acceptable oils. On Chrysler's website, the company provides free, downloadable copies of its vehicles' owners manuals, which contain oil change information.
