For Heads Up = If needed the light Dangerous Stuff

John is this the Royal Purple XPR? I like it but it's roughly $100 for 6 qts!

[GTX JOHN]

Yep............Sorry!
Somewhat cheaper by the Pail.

If that is too pricey = I use Mobil One on my 10 Sec. or slower
Bracket Stuff.

Have mostly used Mobil 1 and Lucas 10-30 in LT1 and LS cars We tried RP in the LT1 but would not keep the lifters pumped up. We have since went with solids (thanks nhra) 2 questions...do I need a additive with Mobil 1 or Lucas? since both cars have roller cams?...somebody mentioned Mobil 1 5-20 high mileage. Is this OK for all the time oil?
What about a safe heads up go fast oil?

[GTX JOHN]

I do not think there is a "Safe" Superlight heads up Oil!

I am always worried with the Superlight stuff and can not wait
to get it to the finish and shut the engine down!

Good call. It's surprising how hard it is to keep enough heat in the oil.

How much heat do you want in the oil?

Does this differ with steel vs aluminum pans?

After the engine has been broken in with a good break in oil, no need to put any additional additives in the oil, especially with a good brand racing synthetic oil.

There are many choices for a heads-up oil, but also consider the clearances you are running. Putting a thinner oil for a heads up run can also require overhauling the engine afterwards. Engine oils have a low surface tension and it operational temperature changes it. It is a risk you take.

Hydraulic lifters require a minimum of oil Centistokes to operate properly. The lower the oil viscosity, the lower the Centistokes. Centistokes is a measurement of the kinematic viscosity on engine oils, that defines the fluid friction and of the oil's film strength to support a load.

A 30w engine oil at 212 degrees F will have a Centistoke reading of 9.3 thru 12.5; however, 5w oil at the same temperature will have a 3 or less Centistokes.

You want around 220 degrees F minimum to get rid of the water vapors and burn any deposits to prevent sludge. Dinosaur oil, 220 degrees F to 250 degrees F. Synthetic oil 230 degrees F to 280 degrees F.
