Volvo Cars have a long and amazing history that spans over years and decades. Starting from 1927, to today, they have been manufacturing cars for over eighty years. And over the years, they have only improved.

Hybrid system – Where the car uses a combination of power sources to run – ie. petrol or diesel and electric. The Toyota Prius is a well known example.

CONSUMPTION RATE – The gasoline consumption rate for every mass-produced car has been carefully ‘designed in’ as a market asset. As an indication, simply observe how quickly and closely ALL the local different gas stations adjust their prices. Even the hybrid cars which use electric motors still consume a designed amount of gasoline, and their price tags are prohibitively high.

Does it smoke? With the engine running, take the oil fill cap off the valve cover. If smoke comes out, the rings or valves are shot and you need to leave now. It will be an expensive repair and perhaps a complete engine rebuild.

Your muffler is one of those parts you’re unlikely to think about until it fails. When it does, you’ll hear it. The problem is, a failing muffler can also be dangerous. If corrosion causes a breach or leak, fumes can escape. This exposes you and your passengers to harmful carbon monoxide gases.

The RMM (or Rod Millen Motorsports) Cat-less Downpipe is the most commonly used. However many other brands exist. Some down-pipes, such as the Random Technology DP, feature an emissions legal high-flow catalytic converter recyclers.

Test the acceleration. Try to accelerate quickly from a stop, a couple hundred feet is more than enough distance for this test. It should accelerate nicely, if not, you are looking at some adjustments or repairs. If it sputters and dies – this is not a good sign. It could be simple, it could be a big problem. Have a mechanic look at it before you buy if you just gotta have THIS car.

What comes out of the tail pipe is ideally something that has already been filtered. This will help trucks reduce the pollution they inevitably generate. One must remember that the engine needs clean fuel too, hence the installation of assemblies such as the emissions and exhaust system. After all, what comes in to the truck is what comes out of it. So if one will only feed the truck clean oil, then the emissions will be cleaner too.
