AutoKarnet advice
BMW N46 petrol engine (2.0 l four-cylinder)
This applies to every car fitted with the N46 engine.
What the N46 is
A naturally aspirated 1,995 cc four-cylinder petrol engine (84 × 90 mm). BMW’s workshop documentation lists it in the E87 1 Series 118i and 120i and in the E90/E91 3 Series among others; for the E87 118i, BMW gives the 100 kW N46B20U2 version. The direct-injection N43 and then the turbocharged N13 replaced it.
Engine oil
Oil change with filter: 4.25 l according to TIS data for the N46. Longlife-04 is approved for petrol engines only in the EU, Switzerland, Norway and Liechtenstein; elsewhere, use the approval BMW specifies for the country. CBS calculates the oil service; from September 2008, BMW encodes a 30,000 km starting value for the N46TU (except in countries with a shortened provision): a forecast adjusted to use, not a guaranteed interval.
