[QUOTE="Psykit, post: 663856, member: 25223"] Bro BMW520, seems you already replace most of the stuffs, however your engine oil is a bit heavy, try 10W-40 if you have no issues with engine consuming oil. Also have you ever replaced your pre-cat O2 sensor? I'm not certain on this yet as I've read that it affects fuel consumption very much. BTW, 36 psi is very high, don't you feel bumpy? I'm on 31 psi front and 32 psi rear only. Like all the other members mentioned, it could also be due to short trips you are making. I drive an avg of 55-65km a day passing the "horrigible" PG Bridge traffic. :motz: [/QUOTE]
