Oil Survey

Valvoline in the Shelby
Castrol Syntec in the BMW (meets OEM specs)
Mobil 1 in the 68. (roller cam and rockers)
 
I'm currently running Joe Gibbs racing oil (10W30) at the instruction of my engine builder, Mark Biddlle of Panhandle Performance:

Since the oil won't be changed often, the oil we need to run is from Gibbs and is designed for hot rods that sit for long periods of time. It has an additive used by the military in their stuff so the oil won't go bad like a conventional will.

Mines a full roller engine, so I'm not into the whole zinc/phosphorus thing. However, I'm not sure I accept the need to run this high-dollar oil just because it's not a daily driver. When the weather's nice, it'll get out most weekends. Not so much in the dead of winter or summer. I probably won't put enough miles on it in a year to require an oil change, though.

I'm thinking about switching to Mobil 1 next time...
 
Rotella T, 10W40, I think. Why? At the time, it was the highest zinc content oil available at parts stores. Royal Purple, Brad Penn, Joe Gibbs stuff is not stocked in town, and neither is red STP. I'll be probably getting ZDDP from Eastwood and adding it to standard oil.
 
Great info guys. Thanks.

I'm going to run Valvoline 20w50 VR1 and add GM EOS for break-in. Mainly due to immediate availability.

After that I'll probably run Castrol GTX Diesel. It has a pretty high amount of zinc.
 
I know this has been beat to death and back but is the zinc the main reason some of you run diesel oil in your cars?

Sluggo, that is the flavor of Valvoline I use. Also using a K&N oil filter this time. Don't know if it's any better than the Motorcraft I have always used but figured for $4.00 more I'd give it a try. Any opinion of filters?
 
I use the Motorcraft FL-HP filter, have for years....works great.Is it better than a 1A? don't know.
