Subject: Re: Amsoil vs Royal Purple vs Valvoline by biggrizzly on 2010/4/28 16:42:01 I helped my buddy Jim change the oil last night in his 2010 Z06. It has the dry sump and takes 11 quarts of Mobil 1, plus the new filter. $$$$ Ouch better find that stuff on sale! He bought three of the Gallon jugs of Mobil 1 at Sam's Club. Still costs over $75 to change the oil |
