After 75,000 miles, 95% of all cars will develop oil leaks. That's the nature of pressure and gravity. It appears that Italian cars are the worst and Japanese cars are the best. All the rest are in between with maybe Honda the best.How much are you willing to spend to have a clean undercarriage and garage floor? The Audi with it's awd system is especially prone to oil leaks, front and back. My Audi dealer is always pressuring me to have all my seals and gaskets replaced(I have 87,000 miles). For a mere $ 5000!. Guess what, I decided to save $ 5000. and instead regularly check my fluids( My car lift facilitates the job) and bought a nice mat for under the car. Also, as the engine oils are dropping in viscosity andgoing all synthetic, it gets harder for seals to keep everthing nice and tight. And, the benefit of living in the Northeast, much less rust under the car during the winter! Oil is good. The solution? We need to pressure the car manufacturers to build better seals. Tough job because it is a great$$$ money maker for dealers.But, if we get the various green car people on the bandwagon( how many barrels of oil would we save in a year, in the world, were we to eliminate oil leaks? And how about pollution from that dripping oil?) we can start a green movement that will please us all!

Any comments?

 

<shrugs> My car does not leak any oil. Many of the seals are original. I hate a leaky car.

 

Just for contrast, mileage is now over 140k and all seals are original. No oil leaking (at least none hitting the floor) with the belly plan in place and the engine is clean. I've used Mobil1 0w-40 since I bought the car with 37k miles and the original owner told me he always used synthetic. Go figure.

 

203,000 miles just replaced valve cover gaskets for under $60. No more oil leak. I have all new seals sitting in my garage but I'm not in a rush to put them in since I'm not leaking any oil.

 

x4, never had a leaky engine on any of the cars ive owned that ive done the maintainence on... well im not counting project cars that were hackedup or jerry rigged

 

please no green movment, please leave it alone.

 

I cannot believe those of you who have over 100,000 miles don't have oil leaks! Obviously, you've never checked your cars out under a lift. Or, you're constantly torquing bolts and washing your engines. Come on fess up!

 

By the way TT2Cabo, we can start by buying your girlfriend a much tinier green bikini and making her the official Audi Green maskot! Do you think she'll go for it?

 

honestly i believe your talking more about condesing oil vapors forming gunk and deposits rather then a sustained dripping leak

 

What you're asking is almost impossible. Yeah cars leak, it's a normal part of life. If you can't afford to have the dealer fix it, go to an independent, or do it yourself.
