1990 Infiniti Q45 Oil Change Questions

  • Should I check my Infiniti Q45 motor oil level? Engine oil is a lubricant for the moving parts in your engine. If you're low or out of oil, engine parts can grind together, overheat, and cause your Infiniti Q45 engine to fail. That’s why you’re better off checking your oil levels and investing in routine lube services.
  • Can I change my Infiniti Q45 oil at home? First off, changing your own oil isn’t as easy as you’d think. It requires special tools and old oil must be disposed of properly. Having your oil professionally changed reduces the chances of something going wrong with the oil change, but it’ll also help your car perform smoothly down the road.
  • Why is my Infiniti Q45 exhaust smoke grayish or blue? There could be an oil leak and your engine is burning oil. Looks like it’s time for a professional to take a look. The leak could be the result of worn valve seals, damaged piston rings, or worn cylinder walls.
