Tempest,
That was the uneducated response I was waiting for. You must be Charlene Blake's husband, or mechanic.
You obviously DID NOT read EXACTLY what I wrote. I will spell it out for you one more time.
First, sludge is a PETROLEUM by-product. Therfore, if you use a TRUE synthetic, you absolutely CANNOT get sludge.
Notice all of my posts clearly specified "100% Premium synthetic oil". This would be a GROUP 4 oil which uses a CHEMICALLY ENGINEERED synthetic base stock for its base oil. This oil does NOT contain ANYTHING petroleum. NOTHING.
Unlike the GROUP 3 [wannabe] synthetic oils that use mineral oil for a base stock. This is your low end "synthetic" and "synthetic blend" oil like the stuff you buy with the Wal-mart brand or other store brand, etc. This is NOT a TRUE synthetic. This is the oil you are speaking about and is NOT the oil I was speaking about. This is NOT a "100% Premium synthetic oil".
I hope this clears up your confusion.
Steve

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. You can view the message here https://forums.noria.com/eve/forums?a=tpc&m=305601547&f=616604995--> A new post from forums.noria.com > Message Boards > Car and Truck Lubrication!
