Acura 2009 RDX - Manual (Page 340)

Reinstall the engine oil fill cap, and
tighten it securely. Wait a few
minutes, and recheck the oil level on
the engine oil dipstick. Do not fill
above the upper mark; you could
damage the engine.
Oil is a major contributor to your
engine’s performance and longevity.
Your vehicle is equipped with a high-
performance turbocharged engine
that requires the use of synthetic
motor oil. Always use Mobil 1
5W-30 or an equivalent oil that meets
the Acura HTO-06 standard. Not all
synthetic oils will meet this standard.
Only use oils that display the
HTO-06 standard on the label.
Failure to use Mobil 1 or an
equivalent oil that meets the HTO-06
standard can lead to a reduction in
engine performance or durability,
and can cause engine damage not
covered by your warranty. Unscrew and remove the engine oil
fill cap on top of the valve cover.
Pour in the oil slowly and carefully so
you do not spill any. Clean up any
spills immediately. Spilled oil could
damage components in the engine
compartment.
