My oil seems to discipate very rapidly! I changed it abo9ut a week ago, then the dip stick barely shows oil....I don't leak any and there are no sings of smoke. My compression is 150 across the board. then engine does have 130k on it (LS engine B18b) 5w30 was used last fill up.

 

well,many miles do you have till you have to add oil?How much oil do you have to add?Info like this would help us out

 

added a quart about 500 miles after i filled up

 

check your pvc valve.

 

do you drive the car hard?

 

yes i do drive the car hard sometimes, not all the time, i'm thinkin i might have mad rings, since comp. is down at 150 like we discussed earlier.
