It does what i wanted it for.
I bought this stuff as a lube for the splines in my lathe and drill press. Very thick and sticky, which is what I wanted.

A good product to thicken oil and add adhesion
Used this to thicken and add adhesion to my truck 15-40 oil for a chainsaw. Worked well enough that I do not feel the need for special chainsaw oil. Many other quality lubrication uses if grease is too thick and 3in1 is too thin.

ZdDP is added to my synthetic oil for my old motor without a roller camshaft to act as anti sheer.
My pre 1986 motor has flat tappers and synthetic oil without ZDDP for better emissions but needs this added to the oil or my flat lifters will wear away.

Used in my 35000kms ran diesel Tiago just after oil change..I poured half of the bottle as the Tiago engine oil capacity is 4 liters and tass used petronas s5w-30 oil..they claimed 4 liters have poured on engine..so in terms of safety precautions I had poured 300 ml on engine.. Oil is very thick ,more than like honey After 75kms the oil began to show the miracle Previously car sounds like Jeep on idiling and heavy sounds of engine after 70kms..now peppy smooth like that of new engine and even better.. It not increased mileage But it makes car to pull stronger and smooth and reducing the diesel sound now excellent peppiness in eco mode!! Use liquy Molly engine flush before oil change!!

I thought that it will make a huge difference though it made little but it's okay nice product to use for old diesel car like when i say old means ... 2-3 years old .... since my car is 2014 and i have used CeraTech once and i drove 1.5L KMS since then ... now i was feeling little bit of vibrations from the engine and also NVH increased .... after using STP it came little down ... Though NVH doesn't bother me that much as i have a nice music system to listen ... but just added STP to keep the engine smooth and running Long lasting ...
