Lexus LS460 frequent oil consumption issue at 2500 miles on Lexus LS460

Some Lexus LS460 owners report experiencing excessive oil consumption, particularly at around 2500 miles, with some needing to add oil every few hundred miles, which can lead to engine wear and potential failure. Many owners have noted having to add a quart of oil nearly every 500 miles due to oil burning issues. While lighter viscosity oil is recommended for proper oil distribution and temperature regulation, acceptable oil consumption is typically around 1 quart per 1200-1500 miles, depending on driving conditions. Internal engine problems, such as worn oil control piston rings, valve seals, and issues with the PCV system, are often cited as contributing factors to this excessive consumption. Additionally, leaky valve-stem seals may exacerbate the issue, and replacing them can significantly reduce oil usage in certain engine designs. If frequent oil consumption is a concern, it is advisable for owners to have their Lexus LS460 inspected by a qualified mechanic to determine the underlying cause and address it promptly.
