I can't think of any reason why not. You could send your current oil to blackstone labs to be analyzed, run the Brad Penn for a cycle and send it out as well. You will then know with a great deal of certainty whether or not there is a reason to, or not to, run either of them.

Tough question. Zinc is used in oil to help break in and maintain high performance engines. I've used it to break in a new cam. Zinc keeps it from flattening.

It's not going to hurt your engine. The only problem I see is that it may end up damaging your catalytic converters. That's why you don't see zinc in oil these days.

uugh why why why Brad Penn old school product that has not kept up with the likes of Quaker State Valvolien, Mobil or Pennzoil. Definately meets specs as a base lube and nothing more additionally the "semi syn" term how much syn is in there???? they do not tell you FYI. example Quaker State says there "semi Syn" is guarenteed @ 25 % food for thought

I'd be concerned about the longevity of the oil. How often do you rebuild your drag race engine vs your Jeep engine?

I'd say you're better off getting a brand-name, quality oil.

I have a Blackstone report on this oil. Very high zinc levels. I might have the report somewhere.

Its a quality oil.

It's a well known and well regarded product. It's simply lesser known across the board than the products you see in the shelf at your chain store. I've never run it simply because I had AMSoil at my disposal for my track car and I never had a bad lab result, thus I never had a reason to change.

To me, all the hoopla about adding extra zinc is totally unecessary with a stock 4.0L engine. I'd only worry about today's reduced zinc levels on a built high-performance engine with higher than typical cam pressures from extra-stiff valve springs.

I happily run conventional 10W-30 Valvoline oil with no worries.

I am in the process of installing a new cam, lifters, push rods and rockers on my 2004 4.0 with 140,000 miles.

Theses motors were designed when motor oils contained zddp ( zinc / phosphorus, etc. ).

I went to a very well known and respected performance machine shop locally to purchase some "break-in" oil / Lubes.

The old timer pointed to several 4.0's that he was in the process of rebuilding. I saw with my own eyes worn cams and lifters just like mine. His very frank experienced assessment was that many "modern" oils were deficient in ZDDP due to federal mandates to protect catalytic converters.

He recommended Brad Penn oil. It has a higher level of ZDDP. Brad Penn oil was previously Kendall Oil. From 100% American Pennsylvania base stock. It is a VERY high grade quality motor oil. It is formulated for various applications. I will use the conventional 10-30 version.

So many of you can "happily" use whatever motor oil you want. If you're running a 4.0, then you can "happily" do this until you suffer lifter / cam failure.

Speaking from experience here.
