I'm 100% in favor of extra additives for protection on new cam break in. I use Torco on everything. It's easy to sit on the side lines riding a stock motorcycle and disclaim things that are truly going on. When your ass is on the line after someone dropped a few grand on a motor job, you take an entirely different perspective on things.

The trouble is that it can't always be pinpointed to the oil. I've had guys contact me about burned up cams that were broken in using all of the top brands of oil mentioned previously. Just last year we had a member report on a drag car that the rings wouldn't seat. It had Brad Penn oil in it and the oil got the blame....so who knows for sure what the reasons are in every situation.

Go hang out with some serious stock car guys for a while and keep your ears open ;) I assure the doubters, it's a genuine problem regardless of what Bob The Oil Guy has on his website.

It happens to the car guys as well as the motorcycle guys. Go hang out with some serious stock car guys for a while and keep your ears open ;)

Yes cam lobes and bearing surfaces should definately be given every possible advantage anytime a new motor is assembled,but its not something that should be worried about everytime you start your motor for the next 20 years as some seem to think it is.
I dont know of anybody who goes out and puts a brick on the gas pedal and holds it there for 500 miles at a time either. :woohoo:

I understand that but if you talk to some of the cam manufacturers, you'll find even some OEM cams that didn't used to fail are now failing. I had an interesting conversation with Megacycle just about a year ago. Not every motor out there is suffering but some of the old ones are now showing problems related to the oil we have available.

Pull the valve covers or oil pan off an engine thats had penzoil run through it even with regular oil changes,youll notice the differance. B)

I believe that :) That's what is so puzzling sometimes about failed valve train components. The oil is an easy target for the blame. I know guys who break in fresh racing engines with Mobil 1 and have no problems with rings seating.

Yeah... the moral of the thread is: the mobil-1, castrol, pennzoil, quaker state, etc we ALL ran in our cars and bikes back in the day are NOT what you can buy anymore, cans may look the same..... oil is not the same.

Learn the facts, make your own choice. Just be advised the oil companies are not talking about it....

And know the ZDDP additives are readily available from Redline or ZDDPlus or others.

Funny... the first warning I got on oil back in the 60's was about pennzoil. The base oil was OK but they supposedly used paraphin based additives that would "foam" when they got too hot in severe service.... don't know personally, I never used it.
