It's a way, way old product from the 1960's.\One of the very first detergent oils.
Formerly called Union 76 Royal Triton.
OK stuff.
I use one half quart of it mixed with my oil changes so I can see my oil level on the dipstick.
That's all it's good for really.
Consumer reports says all oils are the same in their tests.
I believe that.
