Straight STP is there now. A little stiff at first in the winter (like to the end of the driveway) but I don't drive much in the winter anyway.

But the umbrage? How can anyone fault someone else for what they think works! And all those parts SHOULD they wear before their time are replaceable. It's only money.

Dunno. Some think there is only one way.

Shadetree exists to find OTHER ways. And that's part of the adventure. And the delight!

You're right, "It's only money".

As I've posted NUMEROUS times over the last 15 years "STP is NOT a lubricant!" As always, folks are welcome to do what ever they wish with their cars.

For those that haven't seen STP labels, there are a couple points of interest below. The first is an old STP label I first posted in the late 90's.



Now, fast forward 15 years and here is info straight from their web site:


"10. Can I use STP® Oil Treatment in my manual transmission?"

"STP® Oil Treatment has been used successfully in manual transmissions, gearboxes and differentials at a 10% treat-rate, by volume (i.e., 90% oil and 10% Oil Treatment, by volume). Do not overfill."
