@greenvil_omete Here are six signs of oil on spark plugs Sure! Here’s a simpler version:

  1. Blue Smoke from Tailpipe: If there’s engine oil on your spark plugs, they can’t make a good spark.
  2. Gas Smell from Exhaust: If you smell gas from your car’s tailpipe, there might be a problem.

Increased fuel consumption, misfires, and a foul-smelling exhaust are some of the indicators that there is oil on your car’s spark plugs.

Your engine might feel like it’s stumbling or misfiring at idle or during acceleration. This can happen when oil interferes with the spark plug’s ability to generate a spark.

I’ve dealt with oil on spark plugs before, and here are some signs to look out for. Your engine might misfire or run rough, and you could notice a drop in fuel efficiency. The car might feel less powerful, and you could see blue smoke coming from the exhaust. If you pull out the spark plugs, they might look oily or dirty instead of clean and dry.
