You want something with a high zinc content. Quaker State Defy has probably the highest amount of the readily available oils.

The best for older engine types is (IMO)-

http://www.penngrade1.com/

But it is difficult to find (retailer reference on website).

Otherwise any good quality oil (10W-30) if engine is good or (10W-40) if engine is loose plus the recommended amount of ZDDP. HIGH MILEAGE oil is also made for loose engines (tight being fresh).

As stated above; find a place that sells Brad Penn oil.

I read the STP site and saw to no reference of ZDDP.

Simply put, older engine tech needs ZDDP. It is not available in most current SAE oils as its use has been eliminated by EPA rulings.

ROTELLA T has also had its ZDDP content reduced to comply with new emission law (diesel particulate traps). It is no better now than any current SL/SM gasoline engine oil.

Regardless of cost, an older engine needs ZDDP. You can get it either blended into engine oil or buy an additive.

From another forum-

Re: Are new oils ruining our cars? Must Read!

by KULTULZ Sun Apr 25, 2010 1:01 am



Just came across this info from a AMSOIL TECH SHEET-
Quote:
The American Petroleum Institute (API) and International Lubricants Standards Approval Committee (ILSAC), have mandated the reduction of phosphorus to extend catalytic converter life.

However, reducing the level of ZDDP can compromise protection to engine components, most notably in flat tappet camshafts.

Current API SM and ILSAC GF-4 specifications for gasoline engines have maximum and minimum phosphorus levels of 800 ppm and 600 ppm, respectively, for SAE 0W-20, SAE 5W-20, SAE 0W-30, SAE 5W-30 and SAE10W-30 motor oils.

All other gasoline SAE grades do not have a mandated phosphorus limit
.
Quote:
I believe that they are just restricting the oils most commonly used in today's car technology.
This is an old post and may be out of date/current tech. Just a mention that all weights of engine oils did not have to meet reduced ZDDP standards. SN is now the industry standard so the above may now be mute.

I am not going to get in on any oil usage arguments, just want to point out that STP has the fact that it does contain DDPP printed on the container. I personally think MOST of the flat tappet wear problem started with the use of inferior Chineese lifters. And that's all I am going to say about that.
