Oil and filter change on the V35A-FTS

DIFFICULTY 2 / 5TIME ≈ 1 hourCOST Oil, a filter and a drain-plug gasket

Symptoms

The oil maintenance reminder is on, or it's been 10,000 miles or 12 months since the last change. Lexus's schedule cuts that to 5,000 miles or 6 months if you mostly drive dirt or dusty roads, make short trips below freezing, or idle a lot.

The fix, step by step

  1. Lexus's GX 550 owner's manual calls for ILSAC GF-6A SAE 0W-20.
  2. You can use 5W-20 in a pinch, but the manual says to go back to 0W-20 at the next change.
  3. It lists 7.7 qt with the filter and 7.4 qt without.
  4. The filter and drain plug are underneath.
  5. On the LC250, which shares the GA-F body but not the engine, owners on IH8MUD's oil-change thread say only the front skid plate has to come off.
  6. Several found the factory filter fitted very tightly, so have a cap-style wrench ready.
  7. AMSOIL's GX 550 lookup gives 30 ft-lb for the drain plug with a new gasket.
  8. Refill, warm the engine, shut it off, wait about five minutes and read the dipstick, as the manual describes.
  9. Then reset the oil maintenance reminder, which the manual lists among the items to initialize.

Tools & part numbers

  • Cap-style filter wrench
  • drain pan
  • torque wrench
  • tools for the front skid plate
  • a funnel that reaches into the filler neck (an LC250 owner found a standard funnel won't stay upright)
  • new drain-plug gasket. An LX 600 owner on the same thread, whose truck has the same V35A, uses Toyota filter 90915-10010. Confirm the filter for your VIN with a Lexus parts counter.
