Guys if you really look around you will find a lot of people are wiping cams these days. Hot rod magazine ran a article on the problems of modern oils and people like Comp cam specify which oil to use on their cams.

Just because it meets specs doesn't mean those specs meet our requirements. The modern spec oil is for pollution requirements and just don't do the job for our older cars. Dino oil has proven to be better for cars that sit a lot like those driven only on weekends. Synthetic runs off easier and is made for the high mileage daily driven cars.

Again because an oil meets specs doesn't mean it works for everyone. Racing oils have to meet the same emission specs as normal oil.
Diesel oil does NOT so so far it retains the important ingredients to prevent wear and in our case wiped cams.

     Most of the mechanics are not that knowledgeable. I know three licensed mechanics in the area and they are parts replacement tech, not original thinkers, not ones to spend time on a computer keeping up with whats new. Mechanics or most mechanics can't replace rear end gears, most can't build an engine.

So don't always rely on your mechanic for the answer, follow forums, find out what's going on out their, read read read.
I constantly get mechanics calling me up asking for advice, their ignorance shows by some of the dumb questions they ask.

Be your own mechanic..

 

        This was part of a very lengthy article about Shell Rotella T containing Zinc Phosphate chemical for flat tappet cams and lifters written by  Hot Rod magazine personnel.

 

       I have in my '80 Vette,'68 Camaro,and my daily driver, a '72 Chevy 1/2 ton truck with a balanced blueprinted Vette engine using Shell Rotella T 10W45 and they are doing fine..

Diesel oil is also being looked at to lower the zinc content but for now it is still loaded with important additives that we need.
I have $20,000 in a motor that I don't want scattered because of a poor grade racing oil or any other.
