What oil does a 94 LS400 take?

The 1994 Lexus LS400 (also known as the Toyota Celsior) takes 5W-30 motor oil. This is the recommended oil grade for this vehicle according to the manufacturer's specifications.


Detailed Explanation


The 1994 Lexus LS400 is a luxury sedan that was produced by Toyota's premium brand, Lexus. It was powered by a 4.0-liter V8 engine, which required a specific type of motor oil to ensure proper lubrication and engine performance.


According to the owner's manual and maintenance guidelines for the 1994 LS400, the recommended oil grade is 5W-30. This is a multi-viscosity oil that provides good flow at low temperatures (the "5W" rating) while also maintaining sufficient thickness at higher operating temperatures (the "30" rating).


The use of 5W-30 oil helps to:



  • Reduce engine wear and tear by providing adequate lubrication

  • Improve fuel efficiency by reducing friction within the engine

  • Protect the engine from sludge and deposits that can build up over time

  • Maintain optimal performance and longevity of the 1994 LS400's V8 engine


It's important to follow the manufacturer's recommendations when selecting the right motor oil for your vehicle. Using the wrong oil grade or type can lead to increased wear, reduced fuel economy, and potentially even engine damage over time.

What kind of oil does a ls400 take?


The recommended oil for a Lexus LS400 is 5W-30, which is the preferred viscosity for all temperatures. A full synthetic 5W-30 oil is an excellent choice for long-term engine protection. The engine typically requires about 5.9 quarts (or 5.6 liters) of oil when including the filter change, so always check the level after refilling.
 
Oil type and specifications

  • Viscosity: 5W-30 is the preferred viscosity for most conditions. Some owners may opt for a slightly thicker oil like 10W-40 in very hot climates, but 5W-30 is the standard recommendation. 
  • Type: A full synthetic 5W-30 is highly recommended to protect the engine, especially in high-mileage vehicles. You can also use a synthetic blend. 
  • Capacity: The engine requires approximately 5.95.95.9 quarts when changing the filter, or around 5.45.45.4 quarts as a base amount, so it's important to check the level with the dipstick after adding the oil. 

Other tips
  • Always replace the oil filter when you change the oil. 
  • It's a good idea to confirm the exact oil type and capacity in your vehicle's owner's manual to be certain. 
  • While 5W-30 is the standard, if your LS400 has over 75,000 miles, a high-mileage formula with boosted detergents and anti-wear additives can be beneficial.
