Very dramatic overstatement.
quote:that is PHYSICALLY IMPOSSIBLE to get sludge when using 100% premium synthetic oil.
Not true. PAO and esters will degrade, just at a much slower rate. The AO and dispersant additives in the oil are another important factor. Expensive oils (syn) will tend to have better/more AO/ dispersant than cheap dino oil.
The degredation can be easily seen on the oxidation and nitration values in a UOA.
