5 qts plus about 3/4 for a std filter. Your dipstick was modified by Ford to exactly 34.0 inches long from the edge of the top plug to the tip. If it isn't (and I've seen a few that weren't), you should make it so, or calibrate what you have as you add oil to keep from over- or under-filling. The Boss 351C was spec'ed for 6 qts with the very same block, pan & an unmodified dipstick, so a little more won't hurt as much as adding less.
oil man,
My 72 uses 7 quarts, I replace one quart of Mobil 1 with a quart of "Prolong" It cost about 25-29 dollars a quart. I used it in both of my Porsche automobiles with excellent results, as well as my Ranger Pick-up. Prolong is the only additive recommended by Performance Engineering, a Porsche Racing Engine manufacturer.
Oil Man,
I've never heard of the product you mentioned. My memory fails me in trying to remember who manufactures Prolong. I've used Prolong for several years, and one particular car, a DOHC 3.0 litre Mitsubishi come to mind. The car had bad valve seals/guides. I put a quart of prolong in and drove the car 25,000 miles with total reliability and a greatly lessened smoke problem.
Good luck, Larry

Prolong Super Lubricants Settles FTC Charges

Performance Claims for Motor Oil Additive Were Unsubstantiated

Prolong Super Lubricants, Inc., marketer of one of the largest selling motor oil additives sold in the U. S., has agreed to settle Federal Trade Commission charges that the firm made unsubstantiated claims for its automobile motor oil additive, Prolong Engine Treatment Concentrate (ETC). Prolong Super Lubricants, Inc. is based in Irvine, California.

The complaint detailing the charges alleges that Prolong made unsubstantiated claims that compared to motor oil alone, Prolong ETC:

reduces engine wear at start-up; and
extends the duration of engine life.
The complaint also alleges that Prolong made unsubstantiated claims that ETC:

reduces corrosion in engines; and
protects against engine breakdowns.
The complaint further alleges Prolong made unsubstantiated claims that:

benefits that may be achieved by using Prolong ETC in race cars or under racing conditions can be achieved in ordinary automobiles in conventional use; and
testimonials and endorsements of consumers made in advertising reflected the typical or ordinary experience of members of the public who use Prolong.
This settlement is the latest in a series of FTC law-enforcement initiatives targeting claims made by engine treatment manufacturers. The Commission recently charged the marketers of Dura Lube and Motor Up with making unsubstantiated claims for their brands of motor oil additives. Those complaints are awaiting administrative trial. The FTC previously halted allegedly deceptive advertising by the marketers of Valvoline, Slick 50, and STP, other major brands of engine treatment products.

The Prolong settlement would require scientific substantiation for a broad range of claims relating to Prolong ETC, or any other product sold for use in an automobile, relating to engine-wear reduction, engine-life extension, corrosion reduction, protection against engine breakdown, or racing benefits being achievable in ordinary driving. The settlement would also require substantiation for claims made for any product marketed by Prolong Super Lubricants, relating to the product's performance, benefits, efficacy, attributes or use.

In addition, the order would bar misrepresentations relating to tests, studies or research, and would bar misleading demonstrations, pictures, experiments or tests relating to any product's features, superiority or comparability. If Prolong employs user testimonials or endorsements in promotional material in the future to depict typical consumer experience with any product, it would be required to have scientific substantiation for the representation, or disclose what results ordinary consumers could expect to achieve, and the applicability of the endorser's experience. Finally, the settlement contains certain administrative record keeping and reporting provisions to allow the agency to monitor compliance.

The Commission vote to accept the proposed settlement was 4-0, with Commissioner Orson Swindle concurring in part and dissenting in part. In his statement, Commissioner Swindle said,

" I support the provisions in the proposed order prohibiting Prolong from making . . . claims in the future without adequate substantiation. The consent agreement, however, also contains provisions prohibiting Prolong, in connection with the sale of any product, from misrepresenting the existence or results of tests and from misrepresenting that a demonstration confirms the benefits of a product. While firms should not misrepresent the existence or results of tests or demonstrations, it is inappropriate to include specific establishment and demonstration requirements as remedies in an order without corresponding complaint allegations. In this case, and in others from the recent past, there is a troubling lack of symmetry between the complaint and the order."

An announcement regarding the proposed consent agreement will be published in the Federal Register shortly. The agreement will be subject to public comment for 60 days, after which the Commission will decide whether to make it final. Comments should be addressed to the FTC, Office of the Secretary, 6th Street and Pennsylvania Avenue, N.W., Washington, D.C. 20580.
