Oil Survey

OK, what brand, weight, and additives are you using for engine oil. If you don't mind the extra work, tell me why you made that choice.
 
I use Valvoline ZR1 racing oil with zinc phosphate, 10W30. I use it because I have a flat tappet cam and it is designed with higher levels of zinc.
Racing Oils contain additional additives for increased horsepower and reduced friction on metal parts, provide extra wear protection for high compression/higher horsepower engines, and include less detergents than regular conventional motor oils.
What solutions does Valvoline offer to the zinc issue?
Valvoline offers two solutions to the zinc issue:
Valvoline VR1: Contains 75% higher zinc than SM motor oil with a balanced additive package designed to work in both racing and street-legal applications. This product will protect older style push-rod and flat tappet engines. Valvoline provides this product in both multi and mono viscosity grades: 20w50, straight 50, 10w30, straight 30, straight 40, and straight 60.
Longer-Lasting Zinc/Phosphorus: Valvoline uses an advanced zinc/phosphorus additive that keeps higher levels of phosphorus in the motor oil where it protects the engine instead of poisoning the catalytic converter. Valvoline is the only brand offering this unique additive across its entire line of passenger car motor oils including SynPower -- the only synthetic offering this additive.

I use Brad Penn's green racing oil in Red and the goat, lots of zinc. When we finish building Shag's motor guess what oil the builder insisted I use? Yes, Brad Penn.
 
I use Mobil 1 15W-50 in the Goat and Fairlane, both hydraulic flat tappets. It is supposed to have 1200+ ppm zinc, and has worked fine for me for years.
 
I used the Valvoline race oil (dino) for the first year, Redline 30wt race oil since. No oil related problems so far, only idiot Mark problems :eek:mg
 
Royal Purple in both my '66 and daughter's '67 (both flat tappet).

I use Valvoline synthetic in the '69 (all roller, baby).
 
Mobil 1 15w50 in everything except the wifes car - it get M1 5w30. No roller cams in the mix, since my 5.0 block is still waiting for machining. :cry
 
I use Valvolive VR-1 Racing 20w-50 and had been adding a bottle of STP (red-top) for 2-stroke engines (could not find it last week when I changed the oil again) as both have higher levels of the needed flat-trappet anti-wear properties. The engine internals are original, 116k miles.
 
Mobil 1 in the stang and wife's car. Both have had Mobil 1 since day one. Everything else gets Castrol. 10/30 weight on all with no additive. The Blazer (castrol engine) has the 4.3 and has 180,000 miles on it with 0 engine issues. With some of the 4.3 issues I've seen, that's enough to tell me the Castrol is doing ok.
 
351w hydraulic cam & rockers

After running Rotella for the first 2000 miles, I switched to Amsoil 20-50w synthetic.

My decision was narrowed down to Royal Purple, Brad Penn or Amsoil. After reading a bunch of oil data, I picked Amsoil, but I think you'd be fine with any of these oils.

CMayna sent in a bunch of oil samples to be tested. Maybe he could post those test results again? Craig???
 
Interesting info on them. Their oil typically has twice the amount of zinc anc phosphorous than what I am using (not sure if that's important for my engines - the Stang has over 150k on the clock).... but interesting nonetheless.....
