"We found a lot of fuel in the previous sample from this LTD, but that cleared up nicely this time; the flashpoint was high enough to show no significant fuel dilution. It's a bit surprising, then, that the viscosity stayed as low as it did in this report, since we thought last time that the fuel dilution was the most likely cause for the lower viscosity. This sample also saw an increase in iron, showing more wear at steel parts, although at least lead (from bearings) didn't go any higher. All in all, no real improvements, but not
that much worse either. Check back next oil."

you should start your own iron mine!im thinking that your losing a cam lobe,was pretty common in the late 70's from the big 3. have you tried a 15w40?

aside from your wear metals the oil's actual additive package looks pretty good.

How is the car operated?

Thank you for posting, don't see a lot on the oldies smile

I think Delo 15w40 may be a nice choice for this vehicle. If you would like to stay with a PCMO, step up to a 10w40.

That engine desperately wants thicker oil.

This one's my mother's car and she only drives it about 3 miles to work and back. I've used a 50/50 of leftover QS defy 10w-30 and Service Pro XHD30 for the new fill.

Agree with others. Diesel 15/40, CI, if you can find, is preferable over CJ

This doesn't look good, but we have nothing to compare it with.
It may be that all old Ford 351s (C,M or W) shed metals like this.
Good to see a post from you, though.
Haven't seen that much of you since the epic Granada thread.

Wonder how well a classic car formula 20W50 would do?

A 20W-50 would do wonders for that Ford. My 1978 Cadillac loved Exxon 20W-50.

Haha - a 36 year old car with 30k miles and you guys freak over 78ppm iron? Man, at that rate, it may not make it another 36 years and 30k miles. Better switch to some Pure GTL Super Synthetic Hi Tri Nuclear Moly Wonder oil to keep this beast alive! Funny stuff - run a jug of SuperTech 10W-30 (or whatever else you have laying around for the last decade) in it every few years and call it a day.

With his mom's short trips, 20w-50 would be pointless. The three mile trips are the biggest danger this engine is facing.

That engine needs thicker oil at all temps; from startup all the way to whatever the oil temp is at the end of three miles. If there was a way to get engine assembly lube in there between the lifters and the cam lobes at every startup, that would be ideal. 20W-50 would be an excellent match for that old Detroit iron.

But even a 0w-20 would be thicker in those three miles than a 20w-50 would be at operating temperature. wink 20w-50 isn't a good match for much of anything, unless something is worn out to high heaven.

It was an excellent match for my Dad's Cadillac DeVille with the 7.0L V8. The engine ran much smoother and quieter on Superflo 20W-50 than it did on VWB 10W-30. The engine wasn't worn out either, it only had 15K on it after a rebuild. It ran so quiet on 20W-50, all I could hear was the air being sucked into the carburetor and the fan belts going around. Add that sound with a very slight gurgle exhaust note from that beautiful V8 and it was music to my ears. The car would lay a patch of rubber 25ft long on the pavement ... and that was with stock 2:73 gears. I miss that car dearly.
