Toyota Highlander Excess Engine Oil Consumption

(5 reports)

Sludge can build up in the engine because Toyota did not recommend frequent enough oil changes. Lexus will sometimes offer a discount on cleaning the engine if necessary. Owners who changed their oil every 3,000 miles did not experience these problems. This sludge build up can lead to excessive oil consumption.

Plan to have engine flushed with detergent. -
Suddenly started using one quart of oil per 100 miles but only on highway 60 mph or more. Around town used no oil. Regular oil changes were always done. -
3 quarts of oil in 500 miles, so much for toyota reliability. I sould have bought another Ford. -
