i have a 2005 s/c tc with 48K miles.. i recently had an oil change with mobile one and now i have notice that its leaking oil... i took it in to the dealership and they said no leaks..... so they filled her up and it leaked again.... so i took it back in they said it was bone dry( meaning no leaks)... i have had the car since november 07 and it has not leaked until about a month ago now.... also whenever i get give a lil gas it shoots out black smoke>>> any ideas on what this can be??? has anybody expiernced this problem?

 

maybe you're running lean? and where is the oil leaking from? cause its an issue with the s/c's that they leak oil but it could also be a leaky head gasket or something.

 

my car is now stock with just super charger with no other mods.. i cannot find a leak nowhere... could it be internally??

 

well where are you finding the oil?

 

not on the dip stick.... its got to be going somewhere right??

 

how much oil did you lose? your manual says the more you beat on it, it'll start to lose oil and will need to be refilled.


if not, then find out where the leak is coming from.

 

like i got my oiled changed and about two weeks after it was about a quart and a half low.. so i filled it up and within a week it was about a quart low and today which is about a month its about half a quart.. do you think possibly the motor is not taking the synthetic and its too thin??

 

Try not to drive it hard and see if that effects the oil consumption. Your car should not smoke. Black smoke is caused by running too rich. when oil burns and comes out the exhaust it is a blue color.

 

i know black smoke is caused by being too rich... what could be wrong with it???

 

I recommend getting a piece of cardboard about 2 feet x 4 feet and lining it up with a known point under your car so you can find where it is coming from. As far as your car running lean it may just be a cooinky dink that it started happening after your oil change but I doubt it. I would check to see if maybe your MAF sensor was disconnected by accident or something to possibly cause you to run lean. Sometimes the mechanics can get their shirt snaged on something and accidentally pop connectors out and stuff. Good luck

edit: nevermind on the MAF sensor if it was disconnected you should have a CEL
