Pennzoil rates its oil has the highest amount of cleaner installed in its processing

I'm am interested in the conventional oil only. could this oil eventually loosen up
particles of sludge in the motor and have them even in do time clog up the small oil passages.

Two equally slugged/neglected engines..

Fill one with the new pennzoil
Fill the other with diesel

Any given time span, minutes, hours, days etc etc e one filled with fuel oil will be cleaner after draining.
 
Any cleaning an oil will do will do it slowly. Its first job is lubrication. It's not a solvent like many seem to think it is, especially PYB.

HOWEVER YOU SHOULDNT REALLY USE A DIESEL OIL IN A GAS ENGINE? RIGHT?

They the advertiser's say the Pennzoil removes 40% of the sludge within the very first oil change.

Diesel fuel is an oil, and also very solvent. Fill to the brim. Leave it overnight, dump it out and everything will be spotless.
Fill with new pennzoil, leave it overnight and drain and it'll still be the same colour.

OP was asking about the cleanest oil - brand new they should all be equally clean but what I thought he meant was "which oil has the best cleaning ability'? To the best of my knowledge it's diesel.
 
Have a look at my valves..nothing but group 3 synthethics. All of them have good cleaning power
