What is the engine oil capacity of the BMW 3 Series (E90) (2005 – 2008)?

Engine oil capacity with a new filter is 4.5 US qt · 4.25 L. This is the service-refill quantity, not the dry/overhaul fill; add most of it, then top up to the dipstick mark and use the viscosity grade listed above. Verified from the manufacturer's documentation and cited.

What is the coolant capacity of the BMW 3 Series (E90)?

The total cooling-system capacity (including the heater core and expansion tank) is 7.6 US qt · 7.2 L. A routine drain-and-fill replaces less than the full system, so bleed the air and re-check the level warm. Use the coolant type specified for this vehicle — mixing incompatible coolants reduces corrosion protection. Verified from the manufacturer's documentation.

Per-engine engine-oil and coolant capacities for the BMW 3 Series (E90) (2005 – 2008), read from the manufacturer's owner's manual and cited per value. Oil figures are the service-refill quantity with a new filter; where the generation offers more than one engine the figures differ — match the row to your engine. Fill quantities differ by procedure: a drain-and-fill is usually less than a dry (overhaul) fill — confirm the method in the manual before topping up.
