Okay when i bought my Cavalier i did a 'normal' oil change to it.
And she took 1/2 a quarts of oil inside of 3500 km's wich is probably normal since i redlined it a couple of times to see how fast she was.
Now i decided to make the synthetic move.
I put some Lucas Synthetic oil with and additive to be sure that the engine would have maximum protection and also that winter is comming soon.
Anyway....
I've done 1000 km's on Synthetic.....and she burned 2 LINES on the dip stick!!!! WTF!!! And i'm driving normally without redlining her!!!
I've noticed yesterday night at work that the valves were making noise....so i figured....i'll check th oil.....and i was so pissed off when i saw the dipstick

(((((
So my engine doesint like synthetic oil?? Should i go back to normal oil???
Any help will be appreciated!! Thank you!!!
