drain off critical engine parts, however Castrol Magnatec’s intelligent molecules don’t, they cling
to the engine like a magnet, providing instant protection from the moment you turn the key (this is where a 10W40-20W50 would benefit,because it all won`t drip off the engine`s internals like water and all be in the oil pan,instead of clinging to the internals).
I guess engine oil is always a compromise,a give and take per se. Is ester the *magnatec* ingredient? Because aren`t esters polar,whereas pao`s/grp III`s arent?
I had a dinner sitting at a table with one of the Castrol chemists who worked on the Magnatec project and have been a convert, although not a regular user.
His take was that the UMA (Unique Molecular Attractant) ester molecules formed their own layer on the metal surfaces, and protected in the warm up period where the viscosity was dropping from being cold and thick and holding parts away from each other to allowing closer approaches, and the temperatures at which the additives kick in and protect those areas that rely on the AW additives...
Their test mules used M1-flushing oil-Magnatec-flushing oil-M1 to test that the before and afters were consistent, and the test reflected the test, and they found that the residual UMA improved both the flush and the baseline oil performance for a while (bear in mind it was a test, and short duration).
At the time he was talking to me, he was an employee of another company, and really didn't have anything to gain by talking it up.
