STP High-Viscosity Motor Oil

STP is not a motor oil, it is a additive

Yes I did mean to say motor oil additive.

STP's higher viscosity index allowed it to thicken the oil to fill larger gaps in clearances of OLDER engines.

Among other things, this allowed for quieter starts in clunkers. The oil hung around all night. The thicker mixture didn't help gas mileage.

If I had a race car, I might use it.

I wouldn't use it in my ordinary vehicles, and it's too thick for chain saw lube.

For modern engines in a good condition there is nothing better than a good synthetic. Its good for your pocket and good for the engine.

But do not replace it so often either as with Dinosaur oil......it can usually stay in the engine up to 5-7 times longer....

Such claims usually cause a whole bunch of folks from the USA to get up and disagree, in spite of the fact that they themselves have never used it!!!!! Even if they have, few have the 20 years experience that I have.....all good.

There are several other older blogs where I have detailed my experiences fully, I do not intend to write it all again here.....

We will see what happens......

STP oil additive increases the viscosity of your engine oil. If you need a heavier viscosity engine oil because of a worn engine, buy a higher viscosity oil.

If you have an engine without excessive wear, use the viscosity recommended by the manufacturer. A heavier viscosity will cause a decrease in efficiency.

Use a synthetic oil. Due to its inherent qualities, you will not need to change it as often, and it will increase efficiency.

The best-kept secret is Schaeffer Oil. They are 170 years old, and putting out a product that the winners are using. If you look in the engines of many of the Mobil 1 race cars, you will find Schaeffer's.

Is it true that STP stands for Stay Together, Please?

"Is it true that STP stands for Stay Together, Please?"

No: it stands for "Scientifically Treat Petroleum" (and before that, for "Studebaker Tested Products"). See http://en.wikipedia.org/wiki/STP_(motor_oil_company)

I can sure understand why Studebaker would have been interested in an oil treatment for oil-burning engines. I remember in the '50s that the biggest clouds of white smoke on the road had Studebakers in front of them!
