Oil, coolant, or transmission fluid leaks can lead to significant repair costs, so make sure the ground under the car is free of rapidly spreading pools of liquid. sshepard/istockphoto 5.
With modern synthetic oils and new tests such as BMW's LL ("long life") oil specifications, most current cars can go over 6,000 miles (9,700 km) before needing an oil change. Even most modern conventional oils (also called mineral oils) can take a car engine at least 5,000 miles (8,000 km) before needing an oil change.
This harmful debris along with normal engine wear in high mileage engines causes an increase in clearances between bearings and other moving parts. Low oil pressure may be simply because there is not enough oil in the sump, due to burning oil (normally caused by piston ring wear or worn valve seals) or leakage.
This prevents oil burning and valve guide failure in the future. Although these efforts theoretically would have decreased oil burn, a flawed piston ring design affected all engines without VVT-i. This new engine design, [12] although decreasing oil consumption from some components ultimately caused oil burning in higher mileage examples. [13]
After isolating the pump problem, cars and trucks built for the war effort (no civilian cars were built during that time) were equipped with carbon-seal water pumps that did not leak and caused no more geysers. Meanwhile, air cooling advanced in memory of boiling engines even though boil-over was no longer a common problem.
The California Air Resources Board found in studies that 50% or more of the air pollution in Southern California is due to car emissions. [citation needed] Concentrations of pollutants emitted from combustion engines may be particularly high around signalized intersections because of idling and accelerations. Computer models often miss this ...
Example energy flows for a late-model (pre-2009) midsize passenger car: (a) urban driving; (b) highway driving. Source: U.S. Department of Energy [4] [5] Most of the fuel energy loss in cars occurs in the thermodynamic losses of the engine. Specifically, for driving at an average of 60 kilometres per hour (37 mph), approximately 33% of the ...
