Brad Penn Oil

[Harry L.]

Does anyone have any experience using Brad Penn oil? I am currently using Walmarts API Service oil C-J-4/SM. I have been questioning the different levels of Zn and P , between the 2 oils. Is there any ? I drive a 66 Big Block with factory air. DUTCH

Harry,

Go to the Corvette Forum website and click on the Technical post under the C3 section. There is a sticky post that has extensive tests done on the Brad Penn oil. I currently use it in both of my '71 LS6 coupes.

Harry, I just completed my 68 BB coupe and Brad Penn is what I used and will continue too.

Re: Brad Penn Oil

Harry,

I would vote for sticking with the CJ-4 oil. Here's the Duke Williams engine oil article that explains why:

Ron,

I'm pretty sure the article I provided a link to is the same Duke Williams article that appeared in the Restorer.

Re: Brad Penn Oil

My reasons:
Best protection for my engine (ZDDP + HD additive package)
Local distributor in Houston
Cost $68/ 12 qt case not excessive
Not sure diesel oil best for gasoline engines

specs are not that far off the "Brad Penn" oil and a lot less expensive.

Despite digging, I can't find specs for Shell oil on their site. Other sites mention specs but I'm not going to necessarily trust them.

Ron, I have run diesel oil in my cars since I started driving, 1961. Some of my cars racked up 250,000+ miles with absolutely no problems. I have run Shell Rotella, Texaco Ursa, and Gulf ? 30W and 15W40 with the same results. I was assistant director of maintenace for a fair sized fleet, 2,500 vehicles, and we only had one motor oil for cars, trucks, diesels, and that was the current spec "diesel" oil, from Mil Spec 2104-A to the current CJ-4. There is no reason to have reservations about running "diesel" oil.

Chevron has the most accessible, best formated specs on the Web, and you can be sure that any other motor oil of the same API certification - like 15W-40 CJ-4- will have, effectively, identical specs.

They all have to pass the same tests, and the all the manufacturers have essentially the same additive package to pass the various specifications and tests.

The majors like Chevron-Texaco, Shell, and Exxon-Mobil spend a lot on marketing their C-category products to the commercial market, which is why you can buy the same product under Walmart's house brand for less because, comparatively, Walmart doesn't spend any money marketing their house brand engine oils.

We can lead the horses to water. It's up to them to take a drink.

Yes, it was reprinted with NCRS and my permission in that club's online newsletter.

Re: Brad Penn Oil

Has there been any more changes in CJ-4 oils since Duke"s article in 2008. The last owner of my car put in a COMP CAM 280H Grind high energy. It was not driven much before Me, and this was 10 years ago. Dukes article is very informative and by using the C-J-4 OIL , my cam and engine properties stay up to date . thanks for all your inputs.

Re: Brad Penn Oil

Specific API specifications do not change during their lifetime. At some point in the future there will undoubtedly be a follow-on to CJ-4 as CJ-4 was a follow-on to CI-4.

At the present time I am not aware that API is actively working on a follow-on C-catergory spec, but they constantly receive and review suggestions for the future from API members, which includes all the automotive and engine manufacturers.

Also keep in mine that new API specs are driven by NEW VEHICLE/ENGINE REQUIREMENTS, so it will remain to determine the best available specs that meet the requirements of vintage vehicles that don't have "roller everything" valvetrains.

As I have said before, I would not buy a camshaft from Comp Cams unless they were the last cam manufacturer on the planet and I could not find a serviceable or regrindable used OE cam to install. In particular their "Extreme Energy" product line is probably the least reliable in the entire industry.
