Oil Recommendations ...
I will soon be draining the break-in oil (BR 15W50 recommended by the machine shop) from my flat tappet 454. What are the experts oil recommendations for this engine? Thanks in advance! Craig

I like PennGrade 15W-40. I use that in both of my 1969 cars. The "green" oil. One is a solid lifter motor the other a hydraulic lifter motor.

There are several choices... Valvoline VR-1 is what I run as it has high Zinc content, which is necessary for flat tappet lifters. PennGrade is another choice that also has high Zinc.

You'll probably get a bunch of answers here. I use Valvoline VR1 & always a Wix 1st line filter. Napa 1st line used to fit in that group but unless it say made in the US, it's not a wix in the NAPA box....Joe

I also use Valvoline VR-1 oil in all of my cars, 20W50 and 10W30 type.

I used to order Brad Penn but now use Valvoline VR1 50 w. in my 67 L78. My local Oreillys stocks it.

I've been using Brad Penn 10w x 40 with zinc (green oil) for many years and am very happy with it. I purchase off Amazon and its here in 2 days.
