Thanks guys
I read a memo online that Super Tec was valvoline rebadged
I filled it up with that and ran it on jackstands, drained and refilled and drove it a few miles, will drain it and put some hi zoot oil with additive in it
65 F100, 370,000 miles or so, never had the housing out to clean really good
( cleaned the housing tubes with a bottle brush and solvent, then the housing with solvent 4 times )
