How to check for sludge ?

[thejimrose]

disagree with 'change more and often'. 3k mile intervals is a COMPLETE waste
of oil and $ IMO. 5k [at least] intervals miles is more reasonable and
plenty safe even for a chipped motor. i've been changing the oil in my 1.8 t
every.. once in a while... ish or the past 100k miles and makes great
compression and no sludge [m1 0w40 with big filter and seafoam every other
change]. k04 and ecu for 90k miles [100 to 190].

its not like the ecu makes the engine run hotter longer - you get more boost
on wot runs, for a few seconds at a time. yea temps will go up, yea it's
harder on the oil for those few seconds, but the car has a radiator and
intercooler for just such eventualities. probably less than 2% of total
drive time is the 'chip' doing anything. as long as you're not running her
hard and putting her up hot you'l be fine.

i never sit w/ the car idling either. just stay out of boost the last 10
mins of a drive to cool it down.
