i change oil for a living and have been doing it for 3 years sucks :P but heres a quick story. my friend kept saying MY OILS LOW, MY OILS LOW, so i went over there and the dumbass had his car on his kinda steep drive way . 1. make sure you have the car perfectely flat. go under it and check for leaks. if you dont see nothing that bad mabey you didnt fill it right? get on a flat surface 100% horizontal fill the oil till its fully full and you know for sure. then check it a week later

 

Have you always been using synthetics, I've heard if you switch to synthetic it will cause your seals to leak!? correct me if I'm wrong. Rubber absorbs regular motor oil but not synthetic...if you switch the seals release the regular oil and contract, which could cause oil leaks...Just a though...Matt

 

yep this is the problem I have but I don't lose as much oil as he says he does.............maybe 1/2 quart every 2-3weeks

 

actually its the syunthetic that causes the seals to swell up. The reason why people say that switching to synthetic makes your car leak oil is cause the synthetic stuff is 'thinner'. so if your car already has a lleak or a really small leak, expect it to get bigger with the synthetic.

 

It will make your car leak more! It isn't really thinner though, just slippery as ----! When you break an engine in you aren't supposed to use it because it it too slippery. Won't let parts seat properly. It WILL slip right past your gaskets, and even a turbo seal if the turbo is used.

 

Well if it is the seal trouble... what seals should i replace??
