After reading this great oil article I'm going to use a muti-grade oil. I'll start with 10W30 and see how it does. Maybe a 0W30 or 5W30 would be better.
According to the article if doing mostly under 30 minute trips a 0W20 may even be better. To bad Brad Penn does not make that high in Zinc.
List below is my changes to the oil.
Here is my list and reasoning's
Oil - Brad Penn High Performance Partial Synthetic SAE 10W30 .
High in Zinc 1500 PPM and 1340-1400 ppm Phosphorus
I sent an email to Brad Penn Oil and with in seconds one of the technical engineers calls me on the phone. I explained I have a Flat tappet cam and need a good oil high in zinc. I wanted to know if their 30W break-in oil was just as good as the high performance oil, as far as zinc PPM. He explained how it was different and the zinc was lower in the break in oil then the everyday oil. The zinc in the High performance oil is 1500 PPM compared to the 1000 PPM in the break in oil. I hate that I have to order it but it seems that it is a very good oil and less then $6.00 qt from Amazon.
Power steering- Dextron III was suggested by the person that rebuild my gearbox and pump. I could only find Dextron III in a Napa brand.
I was told to only use GL4 in the Muncie Transmission because GL-5 was harmful to the yellow metals in the transmission.
From their site:
Brad Penn's SAE 80W-90 is specially blended using high quality PENN-GRADE® mineral base stocks and select additive technologies. It is designed to be used with “yellow” metallurgy (brass, bronze, copper) and other ‘soft’ metals used in synchronizers, bushings, thrust washers and other components typically found in classic manual transmissions and transaxles.
Additives - Not yet
Antifreeze - something green, not sure yet.
Chassis grease - CRC Sta-lube Wheel bearing Grease It states premium lithium complex grease for chassis so why not.
