Richard Petty's 1981 STP vs 2020 STP? Let's find out!

Is Richard Petty's 1981 STP Better than the new formula of STP sold now? A big "thank you" to Matt from the LsxMatt YouTube channel for sending the vintage STP to me. STP tested for cold oil flow, thermal breakdown and lubricity. Also, STP was tested by an independent oil testing lab for viscosity, anti-wear additive content, detergent/dispersant levels, and total base number. Finally, a blend of the vintage and new STP was used in a small engine that smokes badly and has a bad knock. Thanks and best regards, Todd

Hearing 1980's and 40 years old in the same sentence hurt my soul LOL

Back in the late 60's or early 70's, they drove around in our neighborhood with a STP themed street rod, and handed out STP stickers to the kids. They were like gold to us kids, and really got the name out. 😊

What's the viscosity of STP?
Independent Oil Lab: Yes.

Originally STP was supposed to be added to old oil, midway through the oil change interval. Used in that fashion, with mineral oil it was helpful with oil viscosity breakdown and fuel dilution. Mixing it with brand new oil makes no sense. Todays synthetics hold viscosity much better. Good video, thanks. You're presentations are a pleasure to watch.

"Both the vintage and the new STP seem ok with giving Supertech a head start." I love the perspective you brought to that.

Great test!

Back in the day (mid 80's) I purchased a used MGB from a used car dealer. It had great oil pressure and no smoking. Changed the oil and the pressure dropped and it started smoking as the oil got older. Talked to a mechanic and he told me it was a used car dealer trick to put 2-3 cans of STP in the engine and it would temporarily boost the oil pressure and slow the smoking.

[electronicsNmore]

I remember those cans. You can't dispute the lab results. Thanks for the great video!

I love your video style! We see your face on screen for the intro and conclusion but the content is you showing us what you're doing. You don't spend much time talking about yourself. Other YouTubers should take note of this. Your explanations are clear and not overly dumbed down. I've seen your methods and testing equipment improve over time and you do a great job of giving us those real world test results the rest of us wish we had the time and money to try for ourselves. Please keep up the good work!

You've confirmed what experts have been telling us... That good oil doesn't need additives, generally.

[EarlSinclair]

Project Farm is the most articulate YouTube personality of all time!

[Doctor.Dooms.Diecast]

As someone born in 1981, hearing an oil from that time being called vintage is a kick in the junk. Good video by the way haha.

[Maoshung]

I have to say my heart cried a bit when you opened that vintage STP. So cool to have something that old untouched.
