I bought a few 2 gallon jugs of Farm and Fleet label 5w40 and it just dawned on me that there is no API circle on the bottle. The label states that the oil meets CI-4 and CI-4 plus standards but I guess I've been taking them at their word, having run the oil in my old Honda cb900f and my 1992 Chevy Cheyenne for some time. I was almost ready to run it in my zrx1200 instead of Rotella.
It doesn't worry me too much in the truck as the oil appears to have been performing quite well but it would be good to know if anyone has the scoop on this oil. Is it even possible to make a lousy 5w40? It is pretty cheap compared to other oils of this viscosity range.
