Exhaust Pipes And Mountings - Lexus GS 350 2013 Warranty And Services Manual

EXPLANATION OF MAINTENANCE ITEMS
Engine Oil and Oil Filter
Replace the oil filter and drain and
refill the engine oil at specified inter-
vals. SAE 0W-20 oil is the best
choice for good fuel economy and
good starting in cold weather. If SAE
0W-20 is not available, SAE 5W-20
may be used; however, it must be
replaced with SAE 0W-20 at the next
oil change. See your Lexus dealer for
oil specifically formulated for your
vehicle' s engine. For instructions on
how to reset the reminder light, refer
to your Owner's Manual.
Note: If you do the majority of your
driving under any of the special oper-
ating conditions indicated on page
44, you should replace the engine oil
and oil filter every six months or
5,000 miles, regardless of the oil
used or the certification of the vehicle.
