..for lubricating my Dillon, RCBS and MEC presses?
Lee Precision recommended STP, that's what they said they use.
And sticky as hell. I had a can of it one Winter years ago in my garge...it would not pour out of the can. I cut the lid off and found it was "jelled" from the cold...had to heat it with a propane torch to get it to pour. I have not seen it for years also.Wow. I haven't even heard of that stuff since my high school days and my 396 Impala.
STP pretty much has the viscosity of peanut butter, doesn't it?
Its sticky because its an additive and not an oil.And sticky as hell. I had a can of it one Winter years ago in my garge...it would not pour out of the can.

Yes, I added a can of STP to the oil when I changed oil im BSA 650 c.c., "Spitfire-Hornet", and 650 scrambles bike. I remember commercials for STP showing how to dip a screwdriver in the STP, pinch the tapered bit between one's thumb and index finger, that the weight of the screwdriver was enough that it would slip through your fingers no matter how much pressure one applied. It was consider good stuff back in the day.Its sticky because its an additive and not an oil.
That's pretty scary. STP isn't a lubricant, it's a viscosity index improver (a.k.a. oil thickener).BoboBob said:Lee Precision recommended STP, that's what they said they use.
It is a lubricant. It contains huge amounts of friction modifiers. Anyone who still runs a flat tappet camshaft is aware that STP is loaded with friction modifiers.That's pretty scary. STP isn't a lubricant, it's a viscosity index improver (a.k.a. oil thickener).
