It is fine. A car burns gas to run and that creates soot. I would not worry about it by truck is 10 years old and has 110,000 miles on it and runs great and there is and always was soot in the exhaust.
No lead fuel tail pipes on any car will have black soot. Gone are the days of leaded fuel and light grey tail pipes. Make sure you buy the recommended Denso spark plugs as listed on the specifications pages of your glove compartment manual. Get ready for a shock when you change them. Toyota recommends changing the iridium spark plugs every 100,000 miles or 164,000 kilometers.
I changed the Denso iridium plugs on my wife's Camry last Summer @ 99,000 miles. The spark plug gaps measured .044 (forty four thousandths) in the 100,000 mile plugs. The brand new ones were checked @ .044. Needless to say the iridium ground electrode hadn't worn at all.
Make darn sure you change the plugs when the engine is stone cold and you coat the threads of the new plugs with Never Seize Compound
That is normal.
If it was a electric car then it would be a issue.
Hi Everybody,
Today after getting home from a drive, I wiped my finger on the inside of my tailpipe and got black soot on my finger. It is a 2009 Toyota Corolla with the 1.8 4 cylinder. The car has 108,000 kilometres on it. All maintenance has been done at my local Toyota dealer since the car was new. Never missed oil change intervals or neglected the car whatsoever. I have no check engine lights and the car runs like the day I took it home. What could be the problem? I am due for an oil change in 3,000 kilometres and I will also change the spark plugs as well as the air filter. Hopefully this will be resolved. You'd think for a Toyota 108K is just a baby still.
