But SAE also allows designating an oil with two viscosity grades, referred to as a multi-grade oil. For example, 10W-30 designates a common multi-grade oil. A 10W-30 oil must pass the SAE J300 viscosity grade requirements for both 10W and 30, and all limitations placed on the viscosity grades, such as the requirement that a 10W oil must fail ...
The B48 engine was revised in 2018, dubbed "B48TU" ("Technical Update"), with notable changes and improvements; a new one-part timing chain as opposed to the earlier two-part, a new separate cooling circuits for the cylinder head and crankcase, and forged conrods and forged crankshaft is now 2.03 lb (1 kg) lighter due to the use of lighter ...
The Mk I Mini One, Cooper and Cooper S all used variants of the Brazilian-built Tritec engine, co-developed by US-based Chrysler and BMW; the Mini One D used a Toyota 1ND-TV diesel engine. In August 2006, BMW announced that future engines would be built in Great Britain, making the car essentially British-built again.
There are three versions of the engine, 1.4 L (1,397 cc), 1.6 L (1,598 cc) and supercharged 1.6 L (1,598 cc). BMW complained about the performance of the engine. According to Ward's Auto, Erich Sonntag of BMW described the Tritec engine as old fashioned and not very effective on function, performance and fuel efficiency.

The mini-rotary viscometer is a device used to measure the pumpability of an engine oil at low temperatures. [1] [2] Engine oils must meet viscometric standards including those determined by the MRV in order to be classifiable within SAE J300 viscosity grades. The requirement was added after the winters of 1980-81 and 1981-82 caused major ...
