Pep Boys has the Penzoil oil change packs for sale that include a bottle of Slick 50. It's good to see that Penzoil has finally stepped up in quality to match a product like Slick 50. Now we know where Penzoil wants their oil placed in the market place, right next to Slick 50. If anyone asks you how good Penzoil is, you can can say that Penzoil, themselves, have answered the question, it's as good as Slick 50. This makes me want to rush right out to Pep Boys and pour some Penzoil.

Barkerman, what product have you been drinking? And whay aren't you sharing!!!!

I believe Quaker State has been packaged with Slick 50 also.

Quaker State must be a stand up product, just like Penzoil, if they sell you Slick 50, too. There are a lot of Penzoil fans around here and I can see why. I just did not know that Penzoil was as good an engine oil as Slick 50 is an oil additive. Now we know that Quaker State, too, is as good as Slick 50. There maketing is becoming so clear I'll bet they could say, 'We lay it on, so you can pour it it'.

And all three are owned by Shell Oil.

As for me, I will stick with Valvoline. They have an excellent additive, Synpower Oil Treatment.

So, TallPaul, we have a third party moving to the level of quality expressed by Slick 50. Now, I know if I want the quality of Slick 50, I can use either Penzoil or Quaker State oil and then stop at a Shell gas station for a fillup. It's good to know that Shell stands for the lofty quality standards extablished by Slick 50. That Penzoil/Slick 50 coupon is still available from Pep Boys. Just becareful, you might get trampled by the Penzoil faithful running down the isles.

As an oil additive manufacturer I'm sorry to inform all of you that there are many products on the market with fantastic claims.
