NOT buying a DI only engined vehicle is the preventative cure BUT since you got it i WOULD use a HPL top line oil or Redline or Motul, + depending on your location-heat where you live + drive a 10W or even 15W- 30 or 40 oil. i rarely move my 2001 TT 225Q actually about 300 hp + torque in the colder Pa weather but see MORE vacuum on my installed gauge with redlines 15w40-50 that i use. engine only has 60 thou but prolly loose + i top up as needed in summer months with Red 15-50 + consumption is minimal even thou i "air it out" at 30 lbs boost!!! i like to support the little guy + considering Redlines cost i could prolly buy a comparable or better HPL blended oil!! my 2001 slightly milder 275 TQ + 250 hp jetta another 1.8T went 200 thou without engine issues on REAL synthetic 10W30 in Pa weather + was my work-fun car averaging 30 mpgs after mods + running great when traded just because for my lo mile 2001 TT roadster my first rag top that i am still enjoying!! one thing is they both had small 4.25 qt sumps so real synthetic was warranted IMO. 10,000 changes while working + driving a thou more or less WEEKLY!!! jetta was great in snow with Quaife + 4 SNOW tires!! i tested a new 2001 wrx as well BUT VW build quality seemed better + it was 5G less, BUT easily put 5G's in the jetta that would surely outperform a stock wrx + NO rust even when traded 10 years later living + driving 200 thou in the NE Pa rust belt!! good luck with your rex's i still like them although i didnt buy one!
