1.8T motors sludged because dealers (or owners) used mineral oil in them.
My friend has 03 1.8 GTI, chip tuned, more boost, cai and bla bla bla to many to remember, he drives car very hard, races it. More than 120k on the odo. No sludge, engine looks very clean thru filler hole, no oil burning ether, or any other issues related to engine.He used only Syntec oil, since 40k when he got it. Don't know what was there before. Probably same way, since car was already lightly modded when he got it.
