What engine oil do you guys run in your strokers?
Do you add Zink to it?
I am running Royal purple because it is suppose to have Zink in it. But wondering if there is something better out there.

Re: engine oil
After talking to (email) Keith @ newcomeracing he suggested Valvoline VR1 oil.
So now just need to figure out what weight.

Re: engine oil
The bearing clearances and oiling system dictate that. The TJ 4.0L is designed around 10W30 (5W30 in very cold weather). Unless you have a specific reason to go with the heavier version, the 10W30 VR1 will serve you well.
