Car Maintenance: Synthetic Oil Change

What's That Coming Out of My Car?

Your car functions because it’s filled with many fluids that allow every part of the car to do its proper job. Without all these fluids all those pieces would constantly be grinding against each other, making your car practically useless. Your Premium Oil Supply has prepared this short guide to help you identify the fluids in your car in case any of them are leaking in Houston, TX.

Looking for Leaks in Your Car

A great suggestion, when looking for a leak, is to use a piece of white cardboard and move it around under your car. The dripping on the cardboard will make the job of finding the location of the leak much easier. The cardboard will also help you better identify the color of the leaking fluid.

Transmission Fluid

You might confuse transmission fluid with engine oil, they look the same color, but transmission fluid is thicker. If it’s dripping, you’ll find it close to the center of the car. Vehicles that have automatic transmissions use a more reddish fluid and in some cases it might even be thinner. Just remember, to identify the leak the location is very important. In case you are dealing with leaking transmission fluid, you should check the seal and gasket, the transmission pan, torque converter, or fluid lines, perhaps they’re broken.


The coolant is one of the easiest leaking fluids to recognize because it comes in really bright colors like pink, green, or yellow; and it also has a very particular sweet smell. It’s more likely that you’ll find leaking coolant in an older car model. Older vehicles used to have hoses underneath the car to empty the coolant into the ground. Modern cars, on the other hand, have a recovery reservoir for the coolant to go back to, there shouldn’t be a reason for them to leak. If your vehicle has a coolant reservoir and it’s leaking, there can be something wrong with the radiator, or the water pump or hoses. It’s always a good idea to check the reservoir tank if your engine has been overheating, maybe you haven’t identified a leak, but the coolant levels are below what they should be.


Water is really easy to recognize: it doesn’t smell, it has no color, and it’s completely harmless. Water is the most common fluid you’ll find dripping out of your car. It comes from your air conditioning system. Here’s how the system works: the air from outside gets taken inside, where the A/C system sucks out all the humidity. The condensation that is formed is drained through hoses underneath your car. The more humid the air is outside, the more condensation that will be formed. A tip for hotter days: turn on the re-circulation switch, your A/C won’t bring in more humid air and your car will get cooler sooner.


Engine oil can be a color between amber and black, depending on how old it is. It can be easy to ignore, but if left unchecked it can cause damage to the rubber hoses or seals. Not only that, it will leave stains on your drive way, become an environmental threat and even risk a fire in your engine compartment. The leak may begin for many reasons; one of the being that the gaskets and seals loosened up because of the heat. Whatever the reason is, it’s important to identify it and fix it. If you do have an oil leak, it’s a great opportunity to try the benefits of a synthetic oil change.

You shouldn’t be driving your car when it’s low on oil, you run the risk of the engine overheating and eventually getting busted.

Brake Fluid

When looking for the origin of a leak in your car, color and location are essential. If you find a leak under your brakes of a yellowish color, it’s the brake fluid that’s leaking. Having lubricated brakes is absolutely necessary for everyone on the road. The brake fluid helps keep the pressure on the hydraulic pressure system which makes the brake work. If the pressure drops you will have trouble breaking.

Ask AMSOIL: How Often Should Synthetic Motor Oil be Changed?

Most motorists now understand that synthetic motor oil performs better than conventional oil. It delivers improved wear protection, offers better engine cleanliness and lasts longer. Not as well understood, though, is how often you should change synthetic motor oil.

Not long ago, it was common to change conventional oil every 3,000 miles/3 months. The practice originated in the 1960s as a way to time oil changes with the seasons. The quick lube market picked up the idea as a way to keep traffic flowing, touting it as an “insurance policy” for your engine.

Improvements in motor oil performance and engine technology have since rendered that guideline outdated. The advent of electronic oil life monitors struck a first blow. GM introduced its system in 1988, and it’s now on tens of millions of vehicles. The state of California has aggressively campaigned against changing oil every 3,000 miles, calling it wasteful. The final stake in the heart of the 3,000-mile oil change came in 2011 when Jiffy Lube, the face of the quick lube industry, abandoned the practice, advising motorists to follow the guidelines in their vehicle’s owner’s manual.

If synthetic oil performs better, it should last even longer, correct?
The fact is, most oil manufacturers don’t recommend a service interval for their products. They generally advise you to follow the oil-change recommendation in your vehicle’s owner’s manual, likely due to most motorists’ unwillingness to go longer between oil changes than what’s recommended in their owner’s manual. 

Why spend more money on synthetic oil if it doesn’t last longer?
It’s a good idea for the following reasons:

Improved wear protection – Synthetic oils are more durable than conventional oils. They form a stronger protective film between metal components to shield against wear. AMSOIL Signature Series 5W-30 Synthetic Motor Oil, for example, provides 75 percent more engine protection against horsepower loss and wear than required by a leading industry standard*, extending the life of vital components like pistons and cams.

Better engine cleanliness – Synthetics’ improved resistance to heat and chemical breakdown helps guard against harmful engine deposits, so your engine remains cleaner, runs more efficiently and lasts longer. AMSOIL Signature Series scored 93 percent better for piston deposits than required to meet the latest API standard.*

Maximum extreme-temp protection – The average operating temperature of a passenger car/light truck engine has risen to 235ºF, and higher under heavy loads. Synthetic motor oils do a better job of withstanding extreme heat, while their improved fluidity in cold weather helps the oil reach components faster at startup for reliable wear protection.

Many vehicle manufacturers now require synthetic oil – Automakers understand synthetic oils help their vehicles deliver improved performance and last longer. That’s why newer Toyota, GM and European vehicles, among others, use synthetic motor oil.

Not only that, but some synthetic oils, such as AMSOIL extended-drain synthetic motor oils, protect so well you can go longer between oil changes if you choose. Many motorists want to follow the guidelines in their vehicle’s owner’s manual. But lots of them still choose AMSOIL products that are capable of extending drains because they simply want maximum protection for their vehicles or the comfort of reserve protection should maintenance be delayed. Others desire the convenience of a once-a-year or twice-a-year oil change.

For these motorists, AMSOIL Signature Series Synthetic Motor Oil is guaranteed for 25,000 miles/12 months (15,000 miles/12 months in severe service). AMSOIL XL Synthetic Motor Oil is guaranteed for 10,000 miles/6 months, or longer where recommended by electronic oil life monitoring systems. They offer an outstanding combination of performance and value.

And, practicing extended drain intervals won’t void new vehicle warranties. The Magnuson-Moss Warranty Act protects you in these situations. Plus, the AMSOIL Limited Warranty provides an extra measure of confidence. For details, visit*

Based on independent testing of AMSOIL Signature Series 5W-30, in ASTM D7320 as required by API SN specification.
