Slant 6 oil pressure woes…

Okay so quick update. I filled it up after the flush. I put in 6qts of 10w-30 and 1qt of Heavy duty Lucas stabilizer. Ran it and let it warm up. Sounded nice and smooth. I tried to take it around the block and no sooner than I get out onto the street, the oil light comes on again. I immediately pull back in and park it. Turn it off and pull the dipstick out. Dipstick reads full. Oil is warm, but doesn’t otherwise feel strange. It spreads out across my fingers the same way it does straight out of the bottle, and feels very very slick. I’m beginning to lean now toward having a sensor issue. I don’t know. Tomorrow I’ll look for problems with the wiring connection and go from there. But I’m done for the day.
