Where did you find it? I can't find Chevron/Havoline synthetic for a reasonable price to save my life.


At the now legendary Advance Auto Parts Havoline Synthetic blow out clearance about five years ago.

$1 / quart, IIRC, as much as you could carry off .....

Still have several cases left after all this time.

The 2004 does not have the M1 on the fill cap nor have I found any documentation to support that it was factory filled with it. However, I believe that starting with the 05's they did come factory filled with M1 from Holden and did have it on the cap. Someone who has or has had an 05 or 06 would have to verify that.
