This is old news. Turbo Buick guys have been adding ZDDP to their oil for years. It's not an absolute necessity, but it's a great and cheap precaution. Good luck finding oil at your local parts store with enough content. Just buy some ZDDP and be done with it, or go roller set-up.

Remember, if you have roller rockers or hydraulic lifter then you're fine it just the cars where the cam acts directly on the lifter/bucket or if you have solid cams. I use Valvoline Synpower since it also has a higher ZDDP content. You can find the spec sheets for the different brands of oil to determine what each weight from the brands contain. If you can't find it, you can also request it from them as well.
