Quaker State???? Any good?

Back in the 90's and even into the 00's you could tell a Quaker State engine just by the burned smell, as soon as you took a valve cover off. Clog up an engine indeed, horrible stuff. Saw it first hand myself.

It was a legit concern back in the day. I've never run Quaker State myself because of it, even though I readily admit it has nothing to do with the oils of today and the myth needs to die, along with adding ATF to diesel to clean things up.
Back when Quaker State was produced from Pennsylvania crude via clay and solvent extraction, it did make an inferior motor oil. Now, though, all motor oil is engineered to meet a sufficient level of performance regardless of the type of crude oil it's derived from.

When I was snowbirding in TX there was an 80's fella that said it was "really high in sulfur" or at least that was the urban legend back then. He still wanted nothing to do with that oil to this day. 😂

There is an element of truth there. Texas crude is "sweet" because it is low in sulphur. Pennsylvania crude is "sour" so it needs additional processing to get the sulphur compounds out.

I believe modern specifications put a max limit on sulfur? Back then I doubt there was any limit.
 
I've used Quacker State off and on for a few years now and in two cars I have gotten some decent UOA with it. The price is right never had a single issue with it YMMV.
 
I have 40 qts of 0w20 and 5w30. I use it in everything from my Honda generator, 1.4 turbo Buick and new Honda V6. Use with confidence.
 
It was bought by Pennzoil way back in the 80's, then both were bought by Shell (SOPUS) in the 90's. It's a very good bargain oil using largely natural gas bases with a mixed reputation based largely on ignorance and apocryphal boogyman stories. It was a fan favorite here in the 90's and I literally put it into hundreds or thousands of cars with no issues..

It's probably similar to Platinum with a slightly different additive package or base oil composition...
You're about ten years early on each of the buyouts, but other than that you're spot on.
 
For $13 a jug just send it.
It's gotta be as good or better than SuperTech or Kirkland.
As my non-oil nerd friends say...
Oil is oil😁
 
This is available through Walmart . . . priced very competitively, even cheaper than Pennzoil, Mobil 1, and others.

Mysteriously my Amazon package said it had to be refunded and couldn't be delivered.

Guessing the $13 price was a mistake and they decided NOT to deliver to buyers.

Although I have plenty of 5w30 in my stash (and a SOPUS fan) I was tempted to order several, but restraint prevailed. However, I couldn't just let a deal like this slip thru my fingers, so I did order one and it did arrive. Thanks for the Heads-Up.
 
I'm still seeing people claim Quaker State is made with candle wax. That story has been around since the 80s that I know of. Uh, no nitwit. Conventional motor oil is refined from "paraffinic oil" which is not candle wax.
