vw says 10k oil change:ahhThe oil looks so bad if they wait to 10k. i change the bug,gti 3k my wifes every 5k. the main topic question was not a serious question right? oil has detergents meant to clean the insides of the motor and with all the emission crap oils have less lubricity and more detergents so the oil not being changed lets all the shit on the bottom of the pan get sucked into the oil pump. I know everyone knows this but if you were serious I just wanted you to save your motor. bg makes a bad ass compression restore and moa. keep the toyota motor running a 400,000 if the body lasts :lol
