Yup, FEBI is like Mother’s milk for a baby. I figured if NAPA says to use it, and it’s made in Germany... And I wonder what the real diff is between all the various formulas?
Back in my youth, FORD spec oil had less slipperiness to make up for harder clutch-disc friction material. so if one was to use GM fluid, the shifts would be slightly harder, IMO a good thing!
I didn’t detect any change in the shift quality, and we made it 3,000 miles home, most of the time cruising at 80mph w 3 step bumpers strapped to the roof!
I may try sell the car, and I may change the oil again. Now I have an eBay dipstick, better than the speedo cable my friend found on the ground in a junkyard to check the oil!
Online chatter said the tranny is VERY sensitive to oil level, a few ounces either way could affect the tranny. BS, I took it to the Merc dealer in Palm springs, and his stick showed 1 qt low. I added 1 more qt when I filled it, so much for every ounce meaning something.
I vidded the entire trip, it’s all on ytube CORVAIRWILD
Great story man! Will check out the vids.
