Lexus LS500 excessive oil consumption issue with no resolution from mechanics on Lexus LS500

Some Lexus LS500 owners report experiencing excessive oil consumption, which can be frustrating, especially when mechanics offer no resolution. This issue has been noted in other Lexus LS models, such as the 2008 LS 460, where owners frequently need to add oil. It's crucial to distinguish between sludge problems and oil consumption problems, as they involve different issues and engines. If not addressed promptly, excessive oil consumption can lead to engine wear and other complications. In some cases, owners find that old and brittle valve stem seals contribute to oil burning during combustion. Replacing these seals with new ones often resolves persistent oil burning issues. If you're dealing with excessive oil consumption in your Lexus LS500, discussing these points with your mechanic may help identify potential solutions and ensure your vehicle's longevity.
