Page 213 2007 BMW X3 2007 BMW X3 ENGINE Engine - Operating Fluids ENGINE Engine - Operating Fluids ENGINE Engine - Operating Fluids 1.0 GENERAL INFORMATION The specified engine oil is extremely important for the operation and service life of an engine.
Page 214 2007 BMW X3 ENGINE Engine - Operating Fluids GOOD THERMAL CONDUCTIVITY/GOOD COOLING PROPERTY Engine oil makes an important contribution to the cooling of an engine. It must transfer heat from friction surfaces, and combustion heat away from affected areas. The oil absorbed heat is carried back to the oil pan where it is transferred to the surrounding air.
Page 215 A single grade viscosity oil has a limited temperature/viscosity range compared with multigrade oils. Due to the limited temperature/viscosity range of these oils they are no longer used in BMW engines and thus no longer listed in the BMW Engine Oil Temperature/Viscosity Table.

Page 220 2007 BMW X3 ENGINE Engine - Operating Fluids All engines normally consume a certain amount of oil. This is necessary in order to properly lubricate the cylinder walls, pistons, piston rings etc. In addition, engines with less than 6,000 miles will generally consume additional oil because the components are not fully seated.

Page 224 2007 BMW X3 ENGINE Engine - SI Techniques - X3, X5 (6-Cyl.) Vacuum is principally used for the brake booster. The vacuum in the inlet pipe depends on the varying engine load. Diesel engines do not normally have any vacuum in the inlet pipe. Vacuum on diesel engines is provided by a pump that generates the required vacuum.
Page 225 2007 BMW X3 ENGINE Engine - SI Techniques - X3, X5 (6-Cyl.) Throttle valve  The throttle valve changes the cross-sectional area of the inlet pipe. This creates an inlet pipe vacuum behind the throttle valve, especially in overrun mode.
Page 226 2007 BMW X3 ENGINE Engine - SI Techniques - X3, X5 (6-Cyl.) Exhaust gas recirculation With exhaust gas recirculation, part of the exhaust gas is take from behind the exhaust manifold. This is then fed back into the engine through the intake air duct. The exhaust gas recirculation pipe is located at the inlet to the intake manifold.

Page 537 BMW Group Fuel System Cleaner Plus uses polyether amine TECHRON® based technology developed and patented by Chevron. BMW Group Fuel System Cleaner Plus has proven to clean up deposits in fuel injectors, ports & intake valves and reduces the harmful effects of combustion chamber deposits. It helps restore performance lost due to deposit buildup.
Page 538 Additionally, vehicle's fuel sending units equipped with silver plated resistor card/contacts are especially vulnerable to attacks by elemental sulfur and/or hydrogen sulfide found in fuels. Adding BMW Group Fuel System Cleaner Plus immediately upon noticing erratic fuel gauge behavior may, in many cases, restore proper performance due to the additive's ability to remove the harmful sulfur compounds from the sending unit's contact surface.
