the zz502 has a roller cam, no need to worry about ZDDP....and all oils still has ZDDP but less of it to protect the new versions of cats
Zz502 owners, what oil are you using??????

Start-up and Break-in Procedures
1. After installing the engine, ensure the crankcase has been filled with 5W30 motor oil (non-synthetic) to the
recommended oil fill level on the dipstick. Also check and fill as required any other necessary fluids such as
coolant, power steering fluid, etc.
2. The engine should be primed with oil prior to starting. Follow the instructions enclosed with the tool. To prime
the engine, first remove the distributor to allow access to the oil pump drive shaft. Note the position of the
distributor before removal. Install the oil priming tool, GM part number 12368084. Using a 1/2" dill motor,
rotate the engine oil priming tool clockwise for three minutes. While you are priming the engine, have someone
else rotate the crankshaft clockwise to supply oil throughout the engine and to all the bearing surfaces
before the engine is initially started. This is the sure way to get oil to the bearings before you start the engine
for the first time. Also, prime the engine if it sits for extended periods of time. Reinstall the distributor in the
same orientation as it was removed.
3. Safety first. If the vehicle is on the ground, be sure the emergency brake is set, the wheels are chocked and
the car cannot fall into gear. Verify everything is installed properly and nothing was missed.
4. Start the engine and adjust the initial timing. Set the ignition timing to 10º before top dead center (BTDC) at
650 rpm with the vacuum advance line to the distributor disconnected and plugged. This setting will produce
32º of total advance at wide-open throttle (WOT). The HEI vacuum advance canister should remain disconnected.
This engine is designed to operate using only the internal centrifugal advance to achieve the correct
timing curve. Rotate the distributor counterclockwise to advance the timing. Rotate the distributor clockwise
to retard the timing.
5. When possible, you should always allow the engine to warm up prior to driving. It is a good practice to allow
the oil sump and water temperature to reach 180°F before towing heavy loads or performing hard acceleration
runs.
6. Once the engine is warm, Double check the total advance timing is 32° at 4000 RPM if using the deluxe
engine configuration.
7. The engine should be driven at varying loads and conditions for the first 30 miles or one hour without wide
open throttle (WOT) or sustained high RPM accelerations.
8. Run five or six medium throttle (50%) accelerations to about 4000 RPM and back to idle (0% throttle) in gear.
9. Run two or three hard throttle (WOT 100%) accelerations to about 4000 RPM and back to idle (0% throttle) in
gear.
10. Change the oil and filter. Replace with 5W30 motor oil (not synthetic) and a PF454 AC Delco oil filter. Inspect
the oil and the oil filter for any foreign particles to ensure that the engine is functioning properly.
11. Drive the next 500 miles under normal conditions or 12 to 15 engine hours. Do not run the engine at its maximum
rated engine speed. Also, do not expose the engine to extended periods of high load.
12. Change the oil and filter. Again, inspect the oil and oil filter for any foreign particles to ensure that the engine
is functioning properly.
13. Do not use synthetic oil for break-in. It would be suitable to use synthetic motor oil after the second recommended
oil change and mileage accumulation. In colder regions, a lower viscosity oil may be required for
better flow characteristics.
Apparently It likes light weight oil 5W/30 then after 12 to 15 hours of break in you can switch to Synthetic. 20/50 is too heavy.

I KNOW THIS IS AN OLD POST BUT, PENNZOIL came out with an oil that is made from NATURAL GAS!?!? its actually clear until they add a few additives and then it has a light honey color, and so far i have heard nothing but good things, i have not tried it yet, but i can only imagine it must run so much cleaner... traditional oil is made from dirty crude oil that they refine, and this new pennzoil stuff is made from clean burning natural gas, so the product comea out being a cleaner oil to start with... I'M GOING TO USE IT IN MY ENGINE...
