Most cars sold today state their fuel economy on their website. So the best way to do this would be to get out a pen and paper and write down several cars fuel economies.
There are websites where you can check the fuel economy of each car. One good website is fueleconomy.gov. You can search about any car to compare the mileage.
No, it could actually decrease fuel economy by decreasing the oil viscosity.
About 90 percent of Auto Insurance Companies will not be in the mix on any single rate comparison website.
I was not able to find any price comparison websites that compare the cost of houses and renting in the London area. You could look at your local classifieds and compare the prices yourself.
Yes, Hybrid engines are good for the fuel economy and they are very enviromentaly friendly. Unlike regular cars, they do not emit any pollutants in the air.
Yes. In my exprience a cold air intake and an exhaust can increa fuel economy. It gives the motor more power so you step on the gas less. Also a modified fuel injection system with proper air mix ratio can increase economy but may decrease power.
Yes, performance and fuel economy will suffer.
There does not appear to be any company dedicated to tire comparison. You may, however, find websites that do reviews. One such website is CarsDirect.
The absolute best cars in terms of fuel efficiency are the newest fully electric vehicles. As they don't run on any gasoline at all, there is really no comparison for these.
The following websites are available that show a cost of living comparison between Toronto, Ontario and Vancouver, BC: http://www.expatforum.com/articles/cost-of-living/cost-of-living-in-canada.html http://www.canadaimmigrants.com/costofliving.asp
Yes, if you have any fuel leaks on your vehicle it's bad. Especially in the engine compartment. If the fuel heats up enough it can ignite for starters. It's also bad for your fuel economy.
I think every mobile website provides such function most of websites i found mobile features comparison, price comparison, comparison on basis of users reviews and many other functions, just check it on Google for any such function you want to check, i am a mobile reviews writer and have found thousands of such websites which you are asking for .You may visit whatmobiles.com etc also. Thanks
