First Marketing of STP's Synthetic Motor Oil ?

[CalYooper]

I had a '69 Cutlass which I switched to STP synthetic oil in the spring/summer of 1970 as my recall is working.
It was available in CA and I used it until it disappeared from the market (the local SF parts stores).

Does anyone recall that far back ?

Interesting, why are you asking?

Do you mean STP oil treatment?

A little online sleuthing says, yes indeed they offered a synthetic oil way back when. I was pretty young but recall it as well, and why I did the check.

I love old stuff like that. Thanks for posting.

Am I missing it, or where does it say synthetic?

15,000 miles OCI? Back then norm for mineral oils was 3,000.

wow a 15,000 mile non synthetic oil way back then. and it was not uncommon for manufacturers to recommend the filter to be changed every other service.

"Up to" 15,000 miles. Optimistic marketing.

I sure do not remember anything about this oil. I also don't remember ever seeing a 10W50 oil of any kind. Would like to hear more about this product.

I found this on eBay. You could also write them for a brochure with more testing pictures.

I do recall seeing those cans around during the early to mid 1970s. Back then I was working after school at full service gas stations close to home. I do recall how it just simply vanished and I did not hear or know anything about any STP motor oils again until within the last 4-5 years. Suddenly, STP "fully synthetic" motor oils started showing up at Walmart and AutoZone.
Found this current STP motor oil info:

I guess I would think they would have used the term “synthetic” of that was the case, Mobil sure wasn’t shy about it when M1 came out.

The fact that the product apparently did not last very long in the marketplace may be a clue to something.

Yeah we didn't have catalytic converters or fuel injection on most cars than at least mine didn't. Running a 289 4 Barrel carburetor. STP oil treatment was the shiznit! I still have an STP hat.

Just another day for "the King / R. Petty" advertising for STP. Guess he did have the STP racer's edge cause he walked away. Woof. What a ride.
