Maintenance

How does this save money?

When the engine is shut off there are still vapors in the intake manifold as well as the combustion chambers. These vapors come in contact with the many surfaces, they dry on the surfaces and form as carbon deposits. Over a period of time they build over and over, causing restrictions.

The restrictions have a negative effects on fuel injectors, valves, throttle plates, variable intake runner plates, intake ports and in combustion chambers on top of pistons, valve faces, spark plugs, cylinder heads and head gasket seal edges. This process will occur regardless of the type of fuel used.

So What is the Problem?

When the engine is cold, carbon deposits soak up fuel needed for start-up. This can lead to prolonged cranking. After the engine warms up, this fuel-soaked carbon dries and forms more carbon. This continues to rob fuel from the combustion chamber and will restrict fuel and air flow, and fuel atomization. This will diminish fuel economy and performance. It can lead to hesitation, stalling and surging. In the combustion chamber, high temperatures make This leads to over working of catalytic converters. Catalytic converters are expensive mandatory emissions devices that fails naturally, so you don’t want to add to the problem!

Carbon deposits actually start to glow and will cause pre-ignition. Pre-ignition is a condition when fuel ignites before it is supposed to. This further increases NOX, and engine knock. Today's highly computerized engines retard engine timing, reducing efficiency, compounding the problems. Head gasket materials over worked and can be weakened. This does take time to build up and could take as long as 15,000 to 40,000 miles to occur.

So What?

Well as the brake fluid is hydroscopic this means it starts to absorb moisture naturally. Because of this, the brake fluids boiling point lowers. This can lead to brake fade and internal system corrosion. Corrosion leads to possible leaks. If the leak goes unnoticed, it will lead to brake system failure, which is a most dangerous situation. Corrosion in system can cause Master cylinders, calipers, wheel cylinders, proportioning valves, hoses, abs valving and seals to bind tear or leak. The importance of having the system flushed is to remove moisture and help stop and minimize the creation of corrosion.

How Does this Break Down?

There is a different criterion for knowing when to change the oil. It's determined by driving conditions, that is how the vehicle is driven. Auto manufacturers take severe driving conditions into account when planning their recommendations. Severe driving conditions are frequent stopping and going, (as in city or urban driving,) short trips (as in running errands around town,) towing (as in pulling a trailer or loading the vehicle with heavy items,) or weather extremes (such as a hot summer or freezing winter) If you use your vehicle in any of the severe driving conditions listed above, then auto manufacturers will recommend more frequent intervals than the average 3,000 mile recommended the change oil intervals.

Don't forget to change the filter each time as well, as filters are also negatively affected by severe driving because the filter gets dirtier quicker with those conditions, along with more condensation and contaminates will be present. To stay on the safe side, changing the oil and filter every 3,000 miles with conventional oil and every 6,000 miles with full synthetic oil, is usually recommended by auto manufacturers.
