V8 engines

However do not let in to the temptation as you will end up with single digit mileage as driving at extreme speed will mean extra power. By maintaining a steady speed will result in better fuel efficiency and one can choose the cruise control whenever the possibility arises. Servicing of the used V8 engine at suggested period and keeping it well tuned up with regular oil change as well as the air filter change will make certain that the engine is operating at optimum efficiency giving greater fuel mileage.

Specifications by the manufacturer should not be ignored as the suggestion is always for the betterment of the vehicle. If premium fuel is recommended then do not compromise as a lower grade fuel will give substandard performance and fuel economy as well. Constantly utilize the exact octane specified by the manufacturer. When the vehicle is standing still at one place, do not let it idle for long, turn off the engine, as it will save fuel from unnecessarily getting exhausted. This will help your V8 engine parts to perform efficiently in its long run.  

There are basically two types of V8 engines. The Cross-plane and the Flat-plane engine. The cross-plane engine has distinctively placed four pins in the crankshaft at 90 degrees to each other forming a cross when viewed from the top. It has been found to be much smoother and balanced but lack in acceleration. On the other hand the flat-plane engine has only two pins in the crankshaft; however at 180 degree to each other. These types of engines have high acceleration and are prone to heavy vibrations causing it to be unbalanced. These are typically used in racing cars for greater acceleration. This permits the racing cars to reach maximum speed in the shortest time possible without vicious shuddering.

The V8 engine went through some fine tuning in the next five years; however the manufacturers who wanted economically viable cars were apprehensive to go in for the V8s. Currently the V8 engines are typically associated with high powered vehicles, and they come as an improved version for many cars around the world. There are many variants available in the market the world over. One of them is a 4.8 liter V8 introduced in 2009, is the next generation small-block engines. They particularly emphasizes on lower emission, nearly 90 percent lower and greater performance than its predecessors from the early 1990s.

The latest series of 4.8 V8 engines are quite economical due to its low maintenance cost. The 5.3 liter V8 provides greater horse power for trucks used for constant towing, they also have similar fuel economy due to its active fuel management system that has a provision to have the cylinders render inoperative when not needed. Post the world war II, there was a strong demand for larger status-symbol cars which rendered the common straight V6 not as much in demand. Straight V8 engines have a hitch with the crankshaft belt which requires a longer engine bay. In comparison the larger and wider body types would have the V8s fit in the same space as the V6. Thus manufacturers could further make things easier and offer the larger engines as possible upgrades to base models. For more information logon to www.automotix.net.
