You got me stumpt on this one... I'll be checking back though... wonder what it could be.

 

welp folks I have arrived again. I found what appears to be the problem..

to make it short I have always ran synthetic in all my boosted cars. After 15 trips to the dealership, and about a months of _____ing at them, I think I have solved the problem I simply switched back to reg NON-synthetic oil. I have drove 1k miles and with no issues I even put back on my 9.5 pulley and meth injection and had my car returned, and guess what! no massive oil consumption as before..

I guess it was all in vain because come hopefully this monday The car engine will be ripped out and completely rebuilt yippy..

thanks for all the help/advice

 

that's it? you just switched back to regular oil and poof? there has to be more behind this...

 

there still may be, Ill get to see the insides monday hopefully if my all the stuff arrives on time. So far though I haven't lost any oil and this is running in boost 80% of the time.

 

I got the same issue. I do have 95k miles now... he he. but I get a huge plume of black smoke at high rpm at WOT. 9.5 pulley, I run synthetic. I am loosing 1.25 quarts every 2k miles. I guess I can try regular oil. Why not. I am about ready to trade this sucka in anyways.
