You not recognising the oils name: spec doesnt sound promising though.

I saw the name on the site, I don’t recall seeing the name before at any auto parts store. We don’t go to the auto parts store very often. Maybe once or twice a year if that. We don’t know what oil was used during the first oil change because it was at a mechanic, and we couldn’t see the name of the second one either as we didn’t do the oil changes. All we know is aside from the vacuum pump leak and the misfire (it was sorted) the car was and is running great.
