We all know race engines means high tech and expensive. Because these engines are only produced in small volume and usually working in high load/high stress circumstances, they usually uses some technologies that are not available in massively produced passenger cars.

One interesting fact is, because the race engine has higher assembly precision standards, there is less energy loss due to frictions between internal moving parts. Therefore, some race engines do have better fuel efficiency when comparing to a similar massively produced passenger car engine.

But some good stuff in race engines may act reversely in cars that are designed for daily driving...

Chinese Auto Maker, CH Auto Exhibits New Concept Car

During the 2014 Beijing Auto Show, Chinese auto maker CH Auto exhibits a new concept car called the “Event”.

Currently for all 2014 Subaru vehicles, the car maker recommends changing the engine oil for every 7,500 miles (this is the minimum requirement).

But we have got confirmation from our Subaru source that, the manufacture will reduce the mileage number to 6,000, starting for all 2015 model year Subaru vehicles.

Different from most of other auto makers, Subaru uses horizontally opposed-cylinder engine (called “boxer engine”) in its cars.  This type of engine has low center of gravity, which benefits the car’s handling. But this comes with expense that other V-shaped or I-shaped engine don’t have.

For example, because the cylinders are lying flat in the engine bay, the engin...
