hi guys , yes they still make it , was reading the various articles on the 1967 loco motion l88 corvette and there low & behold the car had a STP sticker on it, the auto parts store had some in stock , bought a can and put alittle in the oil change for my snow blower .thought I'D ask to see if anyone was using STP in there Vettes, with complaints on oil , a additive might help ??
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.

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.
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.
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.

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