Why Oil change Matters
When it comes to routine maintenance, changing your oil is one of the more inexpensive services. Despite its relatively low cost, oil plays a vital, multifaceted role in your engine, and spending a little money on routine oil changes can help prevent you from forking over large sums of cash down the road.

The Role of Oil
Engine oil provides three key functions in a modern internal combustion engine. First of all, it helps keep engine components working smoothly together. Secondly, the inside of an engine, a place where there are thousands of controlled detonations happening every minute, can be a hot place, and oil helps draw heat away from the combustion chamber. Lastly, it helps prevent carbon and varnishes from accumulating in the engine.

What Oil Should I Use?
There are many types of engine oil, but it's fairly easy to determine what kind you should use in your car. Your owner's manual should tell you the appropriate viscosity of oil - like 5W-30, for instance - that your engine requires, and the viscosity may also be stamped on the oil reservoir cap on the engine itself. Viscosity is the measure of how much resistance a fluid has to flowing. Many would refer to it as the "thickness" of a fluid; honey has more viscosity than water, for example.

There's more to oil, though, than just viscosity. The American Petroleum Institute certifies oil based on performance criteria determined by automakers, engine builders and oil producers. Oils that meet the standards receive the API Certification Mark, which should be easy to see on an oil container.

How Often Should I Change My Oil?
Oil changes are often recommended when a certain mileage or time limit is reached. The most familiar interval is 3,000 miles or three months, but what's more important? The Mileage or The Time?

Why Tune Up Matters?
A tune-up is regular maintenance performed on an automobile, or more generally, any internal combustion engine. An old spark plug causes the engine to starve for spark, results loss of Gas Mileage, lack of power & Hesitation. Most automobile manufacturers recommend a tune-up be performed at an interval of 30,000 miles (48,000 km) or two years, whichever comes first. Tune-ups can prevent a myriad of problems from occurring on a vehicle. Spark plugs have a recommended service lifetime of either 30,000 miles or, in the case of platinum or iridium plugs, 60,000 to 100,000 miles (96,000 to 160,000 km), and old spark plugs may cause engine misfire.

Why changing Air filter & Fuel Filter Filters Matters?
The old filters can clog with use and prevent flow, starving the engine of fuel or air, results loss of Gas Mileage, lack of power & Hesitation.

Why Transmission Fluid matters?
Transmission fluid is a slippery liquid that acts as a lubricant for all of the moving parts inside your transmission. In an automatic transmission, this fluid also serves as a coolant and a viscous fluid that transmits power from the engine to the transmission. A variety of fluids are used for different transmissions. Automatic transmissions use something shockingly called automatic transmission fluid. Manual transmissions use a variety of oils: regular motor oil, heavyweight hypoid gear oil or even automatic transmission fluid in some cases. Your owner's manual will tell you what your transmission calls for.

Should I do this service when it's recommended?
Yes, definitely, regardless of whether you have a manual or an automatic transmission.
Manual:Most manufacturers recommend that manual transmission fluid be changed every 30,000 to 60,000 miles. Under heavy-duty use, some manufacturers suggest changing transmission fluid every 15,000 miles.
Automatic: Service intervals for an automatic transmission vary from every 30,000 miles ... to never. The typical service interval is 60,000 to 100,000 miles. Changing it more often does no harm.

Why do I have to do this?
Manual: In a manual transmission, the problem is not so much the fluid degradation, but rather fluid contamination. This contamination occurs over time as the synchronizers, bearings and gears in the transmission wear out. The resulting metal particles then float around in the lubricant. And we all know that oil with microscopic particles of metal in it does not lubricate as well as clean oil. So if these contaminants are not drained out, they will shorten the life of your transmission.
Automatic: Because more heat is generated in an automatic transmission, automatic transmission fluid actually degrades and breaks down with use. In addition, like in a manual transmission, automatic transmission fluid will also become contaminated with worn bits of the transmission. If these contaminants are not drained out, they will shorten the life of your transmission.

What happens if I don't do this?
If you don't change the transmission fluid on schedule, you'll be lubricating your transmission with metal shavings and other contaminants. This will shorten the transmission's life. The result could be a hefty boat payment to your mechanic. In other words, changing your transmission fluid at the correct interval is a good investment.

Why radiator Fluid Maters?
The radiator fluid is perhaps the most vital part of your car's cooling system. The radiator fluid, or antifreeze coolant, is the liquid mixture of antifreeze and water that runs throughout your car's cooling system and helps keep your car engine cool while running. It also helps to keep the engine block from freezing in extreme cold temperatures when the vehicle is parked.

Periodically Change Your Car's Radiator Fluid
You should periodically change the radiator fluid in your vehicle to help your car's cooling system function at its best. Over time, dirt and other contaminants can build up in the fluid, or it may become acidic. When this occurs, the radiator fluid is much less effective and should be changed. Most car manufacturers recommend that you change the radiator fluid in your vehicle every 24,000 to 36,000 miles, or every 24 to 36 months. However, your personal driving habits will also determine the frequency of needed radiator fluid changes. If you drive your vehicle in extreme extremely hot temperatures often, you may want to consider changing the fluid once a year or every 12,000 to 15,000 miles.

Factory Scheduled Maintenance
If you want to live a long life - you routinely go to the doctor's office do what they recommend and with a little luck you will have a long life. The same holds true for your vehicle. This is what we call Preventative Maintenance. If you want your vehicle to have a long and healthy life you have to maintain it on a regular basis.

Recommended Maintenance Schedule
Maintaining your vehicle when it's new is easy; but when it's out of warranty. Our Recommended Maintenance Schedule in conjunction with the Scheduled Maintenance Services from your manufacturer will help you continue maintaining your vehicle to get the most out of your ride.

Factory Schedule Maintenance Guide
The factory maintenance guide that's created by the car manufacturer every year is model specific and should be used as a minimum guide for routine maintenance. Not all vehicle models require the same schedule so it's important to use the specific manual for the specific year and model. Not maintaining a vehicle by specific factory minimum standards could result in denied warranty repairs.

Normal or Severe Duty Vehicle Operation
Many factory maintenance schedules will have two separate mileage and/or time intervals, one for normal operation and one for severe duty operation. Normal operation means the car owner drives at consistent highway speeds more often than stop and go city driving. Severe duty operations can include a vehicle that does the following:
operated in consistent stop and go traffic
consistently operated at an idle
operated in dusty areas
operated in extremely hot ambient temperatures
towing a trailer
Cabin Filter Replacement

There are many harmful contaminants in and around your vehicle every day. Most newer vehicles have a Cabin Filter that filters these contaminants in the air you breathe when in your vehicle. Make sure you replace this filter as recommended by the manufacturer, normally once a year.

Fluid Exchange Services
Sure I take care of my vehicle, I change my oil regularly. Sound familiar? Your oil is not the only fluid you should maintain or change. There are many systems that need lubricating. Your manufacturer's Recommended Maintenance Schedule helps advice you on when to maintain or get an?oil change

Our Fuel System Service will restore that like new drivability to an engine's performance and keeps it running better, longer and more efficiently.

Why Replace Your Vehicle's Belts, Hoses Regularly Matters?
Losing a belt today can mean big trouble for the engine because serpentine belts are used on most engines to turn the water pump, alternator, power steering and air-conditioning compressor. If a belt snaps, everything is lost and you may be stranded. Older cars use individual V-belts for these various accessories. A blown hose could result in an overheated engine and can cause additional engine damage.

It's not easy to know the true condition of a belt hose by its outward appearance, because most belts and hoses fail from the inside out,? said Rich White, executive director, Car Care Council. The Car Care Council urges replacing belts, radiator and heater hoses at specific recommended intervals to prevent your car from breaking down.

Rubber hoses can become hard and brittle, deteriorating with age and exposure to heat, causing the hose to split, blister or leak. Belts also break down with heat, mileage and age. Every time a belt passes around a pulley, it bends. Flexing produces heat that causes the rubber to harden over time. In addition, if the belt is loose or slips, the wear process can be accelerated.

Typical Service for Belts and Hoses:
- Hoses should be checked at each oil change for age hardening (or softening) by pinching. Any hose that feels rock hard or mushy is due for replacement. Leaking, visible cracks, blistering or any other visible damage on the outside of the hose would also indicate a need for replacement.
- The clamps should be replaced when new hoses are installed.
- V-belts should be replaced every three to four years or 40,000 to 50,000 miles.
- V-belts and serpentine belts should be checked for looseness.
- Replace the timing belt between 60,000 and 90,000 miles or based on the interval specified in the owner's manual.

According to a recent survey, nearly one-third of all cars and light trucks have belts or hoses that should probably be replaced. Proper maintenance of your vehicle's belts and hoses is an easy way to protect your car's reliability and prevent more costly repairs down the line.
