I use it for assembly lube when I build engines. Works great !

You scored major cool points if you had an STP sticker on your bicycle in the 60's.

No doubt!!

What Elba and Hotrod said! I even had them stuck on my dresser!! Still have a can that's so old it says"Paxton Products division of Studebaker" sitting around. Great assembly lube, and helpful when I was driving my worn out flathead six powered '47 Chrysler. Useless in todays engines with today's oils, and pretty much useless in any engine that's not flat worn out.

Remember selling a can of Bardial I think it was called that cleaned Varnish off the engine top end , pumping gas in the 60's , each can had 25 cents in them that you kept . Yes also using STP in my 6 cylinder 1951 Chevy 2 door hard top car.

I did a thread in the NCRS TDB and there were a bunch using it. I still use it for assembly and now they say STP has Zink in it.

If it has zinc in it, I think I’ll start using it in my un-rebuilt 63 327.

I used it back in the 70’s on ‘tired’ engines, helped smoking a bit, for the next 600 miles or so.

My understanding is that STP does have high levels of both Zinc and Phosphorous and thus is useful as an additive in older engines with flat tappets, given the low levels in todays oils. The best is actually the red bottle designated for 4 cylinder cars - if you can find it.

Of course, you could also use diesel oil.

It was the same with my Zundapp moped in West Africa in the 1970s. I had an STP sticker on the gas tank and people thought I was Richard Petty.

Had a 71 Chevelle years ago with self changing oil. It both leaked and burned it. I would add a can of that mud from time to time to stem the tide temporarily...

I tried the stuff in my 65 in the early 70's to slow oil usage. When I tore my engine down for a rebuild I swore I'd never use it again - sticky, nasty stuff, especially when cold.

SDVette

I used to run it in my 76 Vega... Kept the smoking down to a minimum!

In 1963, my summer driver was a $100, '58 Biscayne, 283 with a cracked piston. Used a quart of 30W oil every 50 miles and smoked accordingly along with a lot of noise from that cracked piston.

A buddy came up with 4 1/2 quarts of STP so I dumped it in the crankcase. The smoking stopped, the knocking stopped and I used less than a quart of oil/STP the rest of the summer.

I don't really know what other value that stuff has other than to slow down oil burning.

LouieM

Amazing that your car started at all with that much heavy goo to pump thru the engine.
