Stp

[Brianfrench65]

Is it recommended to add any STP to the engine oil? Any recommendations would be appreciated.

Thank You;

No why? STP is for old worn out engines at used car dealers to thicken the oil and get some oil pressure. Put in the thickness of oil you want so no need for STP. Search the forum. Lots of talk about STP snake oil.

won't hurt, I add 1/2 bottle at the oil change...

Works good used straight in mechanical steering gears.
That's about all.

There has been so much said here over the years about good ole STP. Back in the day when Studebaker owned it we were told to try and sell that crap. We sold a lot of it, but, didn't really try to.
If one had a bad transmitter or rear end whine and didn't want to spend any time or money on it, then one could stick in some STP or walk across the road and buy some bananas. In the end the bananas worked best as you could feed the fellas in the shop
and slip the peels in the offending transmission or rear and the noise would go away. Use the STP and usually the noise remained.
OH, but, you're talking about the engine. It makes good assembly lube.

Look at the can. It says to add it to oil. It is meant to be mixed with oil. Using it straight is not good for anything. This has been discussed in earlier threads.

Yeah, I know it's been discussed to death but anyone that says it doesn't work in steering gears is full of shit!!!!

[Kahuna]

Yes, I remember Bananas & Saw Dust in rear axles. Works good, lasts long time.
Also Pepper, Cinnamon, Canned milk in radiators. All great stuff, ha ha

Heh Pete, don't hide your feelings, say what's on your mind ( lol ) ! Wayne

STP used to come in 2 varieties, a red bottle and the blue bottle. The red contained added zinc, which has been a source of much discussion for classic cars, especially early Porsche flat opposed cylinders, etc. Zinc has been removed from many oils, and the STP zinc product bottle isn't available at least in Cal. to my knowledge, for environ. reasons. One company in Colorado sells a ZDDP product to add to oil not as a thickener but soley for the zinc. ( but not cars with catalytic converters ).

Back in the 60's an older gentleman who was a Chrysler Dealer told me he had good luck with ground cork. I was very young at the time.

The model A engine is essentially an oversized lawnmower engine.

It'll run happily on almost any oil. But please don't add unnecessary snake oil additives to it. For that matter, don't put that junk in any engine.

It doesn't need STP, Marvel Mystery Oil and it doesn't need lead.

AND, it doesn't need zinc!

I put a bottle of STP in all three of my old cars when I change the oil.
I also add it to the 140 wt gear oil to thicken it up for use in tranny's and
rear ends. Works for me with neary a problem. I remember a thread on STP from a year of so ago from what sounded like a professional engine rebuilder. Of all kinds of engines and not just "A's". He always used
STP and every engine he tore down to rebuild/repair that had used STP.
Was found to NOT have any unusal wear or gauling problems and there was a thin protective film of oil/STP coating the complete inside of the motors. Sounds like my kind of snake oil!

If you want superior wear protection, use synthetic oil! STP is a viscosity index improver. Higher viscosity make it more difficult for oil to flow.

Thank you all very much. I appreciate all of the comments and suggestions.

Thank you.

I'm looking for a Band-Aid....

My original motor is worn out and never rebuilt at 84k.

I plan on a full rebuild this winter, but until then it smokes blue in a heinous way.
Runs great other than that!

I'm looking for a way to reduce the oil burn so we can at least enjoy the car this fall, because right now its too embarrassing to chug down the road with a cloud behind...

Any suggestions would be great!

change the oil to 15/50 mobil 1 synthetic.... a good overall weight and synthetic oil burns clear
remember the dipper tray will hold some of the old oil..
