How Often to Change 1991 Lexus LS400 Oil

Not sure how or where to get your Lexus LS400’s oil changed? Get the advice you need at Firestone Complete Auto Care! Our expertise goes beyond tires. We know all about motor oil, too. After all, like our maintenance technician Brianna says, “Oil is the blood of the engine. It’s the #1 thing you can do for your car.”

Your 1991 LS400’s oil should be changed according to Lexus’s recommended oil change intervals. See mileage and month specifics in the above table. Your LS400 may need an oil change right away if your check engine/oil change light is on, you hear knocking sounds coming from the engine, smell oil inside the car, or notice an unusual amount of exhaust. You might need an oil change more frequently than what’s recommended by Lexus if you regularly haul heavy loads, frequent dusty roads, go off-roading a lot, or go at low speeds on long distance trips. Generally, getting more frequent oil changes won’t hurt your Lexus LS400. Each oil change is actually another chance to check and resolve other car issues, such as worn brake pads or tire treads.

Oil Change Q&A for Your 1991 Lexus LS400

  • Why check the motor oil level in my Lexus LS400? Engine oil is a lubricant for the moving parts in your engine. If you're low or out of oil, these parts can grind together, overheat, and cause your LS400’s engine to fail. That’s why you’re better off checking your oil levels and investing in routine lube services.
  • How hard is it to change Lexus LS400 oil at home? First off, changing your own oil isn’t as easy as you’d think. You’ll have to buy special tools and figure out a way to recycle the old oil properly. Getting a professional oil change reduces the risk of something going wrong during the service, but it’ll also help your car perform smoothly down the road.
  • Why is my Lexus exhaust smoke gray or blue? There could be an oil leak and your engine is burning oil. It may be time for a pro to take a look. The leak could be caused by several issues like leaking valve seals, fried piston rings, or damaged cylinder walls.
  • Who does Lexus LS400 oil changes? You can count on Firestone Complete Auto Care for your Lexus LS400 oil change, oil filter replacement, oil leak diagnostics, and more! Our expert technicians will even advise the right oil for your vehicle.
  • What can cause the oil light on my Lexus LS400 to illuminate? Your Lexus LS400 oil change reminder light may come on if you're overdue for an oil change. The oil pressure light will typically come on if the oil level in the engine is too low, the oil pump is failing, you have a clogged oil filter, or there's a faulty oil pressure sensor.
  • Should the oil filter be replaced when getting an oil change for my Lexus LS400? You should replace your Lexus LS400 during each oil change. The filter captures debris and contaminants to help keep your oil clean, which means the filter gets dirty. If you skip replacing the filter, you’ll contaminate your new oil with the dirty filter.
