It signifies that the car is running absolutely correct. Here is the reason why: A gasoline (petrol) molecule is made up as such: C8H18 (or 8 Carbon atoms and 18 Hydrogen atoms) Energy is obtained from the combustion of it by the conversion of a hydrocarbon to carbon dioxide and water. The combustion of octane follows this reaction: 2 C8H18 + 25 O2 → ...

If driving with multiple filters, your vehicle will lose performance. Your car will have a greater restriction in the intake system from having to pass through two separate elements. You would, however, have cleaner air coming into the system, but at a cost of the performance. You'll have to have more gas pedal to compensate which would cause other issues as ...

If you use more than one air filter, you will make it harder for the engine to suck air into the intake manifold, meaning you will lose power. Less restrictive filters will give you more performance, but will allow more dirt into the engine. If you use something like a cone filter (like in the second picture), you will have a change in sound, especially ...

Every gallon of fuel your vehicle burns produces a gallon of water out of the exhaust. If the weather is cold you will see it as steam. If the rear of the exhaust system is still cold even in warm weather it will be for a short time after start-up, you will see the drips. On a hot engine/exhaust you will not see any drips from the tail-pipe. If there are ...

Just some interesting info on high octane fuels the original method of refining fuel had an added amount of lead. The added lead increased the octane value of the fuel which gave the engineneers of old a better way to control the combustion rate in the internal combustion engine. an added benefit of the lead in the fuel was cooler temperatures at the exhaust ...

Reading through some of the Ducati forums has lead me to believe the selection between an open and closed clutch cover on these bikes is mostly for aesthetics. There is some consideration for cooling, but nothing which is earth shattering. So here is a list of pros and cons which I have compiled on the subject: Open vs Closed Clutch Covers - PROS: ...

I pulled the following information from this site: Unless you are a professional motorcycle mechanic, you normally can not see whether a motorcycle has a wet or dry clutch just by looking at the bike. But if you know your Italian motorcycles, you probably have a pretty good idea which ones do. A wet clutch is called wet because it is actually wet ...

Ther are many faults that this can be caused by. A scan on your vehicles engine and transmission would be a good first step. You can try revving the engine whilst stationary and with the e/handbrake applied and the vehicle in 'Park'. If the engine will rev up into the 6000 RPM range you will know the engine is OK. If you cant achieve a high rev, you may have ...

If you say all the hoses and clamps are in good order, then the only other things that come to mind are the wastegate and exhaust manifold. Either the wastegate is opening too soon, or the exhaust manifold is leaking from the gasket or a crack. This would mean that either you lose boost too early, or you never get enough boost in the first place. Or, if ...

The car has not been driving long. As the others have said, the water comes from the combustion of the fuel. When the exhaust system is cold, it cools the exhaust enough that the water can condense. After a while of operation, the exhaust system heats up. The same water vapor is present in the exhaust, but it stays vapor and doesn't drip.

A 'sudden' drop in mileage means a component has failed, especially if it was some time after the service. The first thing to do in this sort of event is to do a leak-off test on the injectors. If an injector has failed this will show it. A faulty injector will allow a lot more fuel through, usually accompanied with black smoke from the exhaust. Second ...

Well most of the car owners prefer alloy wheels because they offer both cosmetic and performance. However, I think alloy and steel both have their own significant points. Quality of an alloy wheels depends on the amount of Nickel added with aluminum in its making, whereas steel wheels are known as “unsprung weight” as they are not cushioned by suspension ...
