I recently picked up a case of Kendall GT-1 5w-30 Dexos 1 motor oil. When I got it home and looked at the outside of the case and the quart bottles I noticed it doesn't say exactly what type of oil it is. I know to meet Dexos 1 is has to at least be a synthetic blend or full synthetic. Does anybody have an idea if this is a blend or full synthetic? I'm never home in time to call the company and find out. Any help would be appreciated.
