Todd at Project Farm is the man when it comes to comparing tools, parts, lubricants, and more. I love his videos and we feature them here on the site whenever one of his tests hits home. This one is from 2020, but it sure is relevant in our hot rodding world since everyone always waxes romantic about everything being better “back in the day”, or “in my day”. I wish I had a quarter for everytime a car guy said something about wishing they had an old part, or the “original formula” of something like STP.
But were things really better back in the day? There is only one way to find out! Watch the video and you’ll see.
Video Description:
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.
Hmmm.
