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.


Pretty much all your advice includes "sounded better or ran smoother". No real data. Running a 20w50 will not make a a difference in a old car that is driven 3 miles. Fuel dilution from a carburetor is more prone to do the same thing to any oil that is ran. Any oil changed at 3k miles intervals would look pretty much the same. The key with this motor is run whatever you have laying around but change it often.

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.

yep, I'm still around. Haven't posted much as driving the Caddy and my new shorter commute isn't very exciting. I'll be doing one more UOA on the caddy as I'll be sticking with 5-6k OCI's on that one until it's dead or not worth running. I'll also add an upcoming treat: a UOA on my backup driver: 63 Chrysler. It's had the Family dollar 10w-40 I used for cleaning in for a year now.
As for this LTD, I'm slowly scaling up the oil grades until I find something it won't kill, but still able to start in winter. Cold starts are a factor on this car.

Unfortunately for the smoothness/sound tests, there are no sound or smoothness benchmarks in any API, ILSAC, ACEA, or manufacturers' specifications. wink

A 10W-40 might hold up a little better and would still allow for relatively easy winter starts.
I used that grade in a variety of engines back in the day and never had problems with winter starts.

That may be next. This fill was 2 leftover qts of 10w-30 Defy, and the rest was my free XHD30. I also had to fill the car before results could come back. I'd thought about T5 for this one, but would it be a waste with no miles getting put on it really?
