On the 2007-2017 Lexus ES, the 3.5L 2GR-FE V6 in the ES350 consumes excessive oil between changes, often burning 1 quart every 1,500-2,500 miles. The root cause is typically worn piston rings that allow oil past the ring lands into the combustion chamber. Toyota/Lexus issued a TSB acknowledging the issue and revised the piston ring design in later production runs.

This issue also affects: Lexus IS, Toyota Highlander, Lexus GS

Common Symptoms

Oil level drops significantly between oil changes
Blue smoke from exhaust on startup
Low oil pressure warning light
Need to add oil every 1,000-2,000 miles

How to Fix

Perform an oil consumption test at the dealer to document the rate. If consuming more than 1 quart per 1,200 miles, the repair involves replacing piston rings and possibly pistons. Use 0W-20 synthetic oil and check levels every 1,000 miles. Some owners switch to 5W-30 for reduced consumption.
