Oil Changes for 1990 Lexus LS400

Not sure how or where to get your Lexus LS400’s oil changed? Turn to Firestone Complete Auto Care! We're experts in more than tires. We know the ins and outs of motor oil, too. After all, "Oil is the blood of the engine. It's the #1 thing you can do for your car," says our maintenance technician, Brianna.

Your 1990 LS400’s oil should be changed according to Lexus’s recommended oil change intervals. See mileage and month specifics in the above table. No matter the mileage, your LS400 may need its oil changed ASAP if your check engine light is on, you hear engine knocking, smell oil inside the car, or see an excess amount of vehicle exhaust. You may also need an oil change more frequently than Lexus recommends if you haul heavy loads, frequent dusty roads, go off-roading a lot, or go at low speeds on long distance trips. More frequent oil changes generally won't harm your Lexus LS400. In fact, every oil change is an opportunity to diagnose and treat any other issues, such as bad brakes or a failing battery.

Whether it’s synthetic, conventional, or a blend of both — your local Firestone Complete Auto Care has the right oil for your Lexus LS400. Lexus has recommendations as to whether conventional or synthetic oil is the best motor oil for your 1990 LS400. Motor oil helps lubricate the engine’s moving parts, keep the engine cool, and keep harmful substances from building up inside the engine. During your oil change service, one of our techs will change your LS400’s oil, replace and recycle the old oil and filter, inspect all of your other filters, top-off important fluids, and perform a courtesy inspection on your entire vehicle. You can drive with confidence knowing that we look out for you and your LS400 by taking into account your driving preferences, and mileage.
