Anybody remember the Prolong oil additive controversy? Interesting forum post here, makes me think there was more to the story than I was led to believe. Did they change the formula for the stuff on the shelf after the litigation?

Quote
Anybody used this? When this first came out, I saw the commercials of Al Unser Sr. driving many laps around a race track, without any oil in the car, but after they had used prolong. All oil was drained before the test. No damage was done. So I was talking with Smokey Yunick one day about this, and he too thought it was BS. So, being Smokey, he tested it. He told me he had tested about every oil known to man, and that ALL of them squished out of bearings at about 300 psi. Anything higher than that, and there was metal to metal contact on mains and rod bearings. So he tried prolong oil additive. He got close to 3,000 PSI before metal to metal contact. Many months later, we were talking again, and word had got out about his Prolong tests. Smokey then said that ALL the NASCAR teams were using it, whether they claimed so or not. I have been running it in vehicles ever since. SO I was thinking, since this Porch engine seems to have oiling problems when hard cornering, we ought to be using Prolong. My last vehicle was a Chevy 1996 extended cab pickup. I ran Prolong and REDLINE Synthetic oil, and grease since day one. I gave the truck away at 218,000 miles. The rear end, inside looked brand new out of the box. The engine ran like new as well. It also still had original ball joints, and they were fine. No I am not a salesman for these products. I first used REDLINE oil in the rear end of my sprint car. The temperature went down around 80 degrees using that oil, and nothing wore out.

I'm not sure if it still does, but Prolong used to contain a good bit of chlorinated paraffins. It can be good for anti-wear but is also corrosive.

Many laps around a race track? Maybe do a 100 and report back. How about just keeping the engine full of oil? No damage will be done either without spending extra for an additive.

Correct! That was it's secret. The temporary lower oil temps could also be attributed to the evaporation of the product.

Here is a note on it: https://fuelandfriction.com/weekend-warrior/dangers-chlorinated-paraffin-additives/

I wonder if that was a German aviation wartime discovery like zinc dithiophosphate? I remember seeing a 1960's era STP display with the wording "Invented by German Scientist" with the circling electrons that was so popular in marketing back then.

Given the short life expectancy of a piston engined fighter corrosion wouldn't be a concern.

Chlorinated paraffins make hydrochloric acid as a byproduct of the combustion process. No thanks.
