Canadian Tire has Formula 1 Full Synthetic on sale for $15.99 / 4.4 litre jug so off I went to stock up on some. When I checked the jug at the store I noticed there is no indication of it meeting Ford Spec WSS-M2C930. It has the API mark and says "Meets industry requirements" Anyone know if this oil meets Ford Spec and how do I get it in writing so I don't have any warranty issues? Thanks.
