The Importance of Brakes on your Car
BRAKES…The most important SAFETY feature of your vehicle. Routine checks & maintenance will not only save you costly repairs, but brake sensors may save your life. Worn discs will issue a grating, metal to metal squeal when pressure is applied to the brakes. At Vaal Autonostics we will inspect your brakes and perform preventative services - before your car’s brakes become a safety issue. ELECTRONIC SENSORS will illuminate a warning light on your dash when a brake pad wears to a point that causes the sensor to make contact with the brake rotor, alerting you of an impending failure. Vaal Autonostics cares for your safety and that of your passengers, and will only install high quality brake components. It is more important how quickly your car will be able to stop, than how fast it can accelerate! Do not gamble with your safety on the road, call us on 016 100 2220 and make an appointment to have your brakes checked.

Synthetic Oil vs. Conventional Oil
“Why should I pay more for synthetic oil?” The confusion over synthetic oil vs. conventional oil is understandable.
The mechanic has looked over your car. Then, he said something about engine sludge, oil filters, and asks when you last changed your oil. Even though you may not know the exact date, you remember seeing low prices on plastic banners. Now, the world of oil changes feels like snake oil sales. Synthetic oil? It’s not an oil alternative. It’s a man-made oil. Ecologically, it produces fewer emissions. It is more expensive at six to ten times the price. But, it is also a better oil.

So, why choose synthetic over conventional oil?
Is Synthetic oil worth the higher cost versus conventional oil?
What is Synthetic Oil?
Synthetic oil is nonetheless oil, though it is somewhat man-made. Synthetic oil is made from a base oil, powder additives, and a carrier oil that enforces an even distribution of the additives.
Refinement processes and ingredients also result in scientific control over molecular size and purity. That can lower friction, reduce engine sludge, and increase performance.

Synthetic oil technological advantages include:
• Uniform molecular size means less friction
• Refinement and engineering reduce deposits
• Additives boost protection and can clean engines
• Better function in cold and extreme weather
• Cleaner oil with fewer impurities
Full Synthetic vs. Synthetic Blend
Full synthetic oils are better understood as a grade of motor oil. Semi-refined--also called synthetic blend--oils are less refined than full synthetic oil. Semi-synthetic oil blends traditional oil with the more technologically advanced oils. You get the advantage of additives and more refinement. But, the impurities and inconsistent molecular size of conventional motor oil are still in the blend at lower degrees.
The benefit of synthetic blends is largely a cost-vs-benefit decision. Synthetic blends are cheaper than full synthetic motor oil but higher performance than conventional oil.
Oil change Intervals
Because synthetic oil is better on your engine and has fewer impurities, it can go longer than conventional oils or synthetic blends.
Schedule regular intervals. For conventional oil, twice a year is suggested as a safe way of keeping track. If you want to keep better track, every 12,000 kilometers is suggested for average cars. You should also change your oil filter every oil change. But, especially if using synthetic oil, every other oil change is sufficient if you don't regularly push your car hard or endure extreme conditions.
Check your owner's manual. Newer cars may be able to go 16,000 kilometers or only need an oil change once a year. Turbo engines and older cars may still require oil changes every 4,800 to 8,000 kilometers.
Synthetic oil change intervals range 16,000-24,000 kilometers or once a year (whatever comes first). Extended performance synthetic motor oil is on the upper top of that range. That extra 8,000 kilometers may be worth the investment.
Synthetic Oil vs. Conventional Oil
Visually, you cannot tell the difference between new synthetic and conventional oil. There are two major differences, however. First, how they are made is a distinction. We've explained that synthetic oil is far more refined than conventional oil.
Second, the way they run in your car is worlds apart. Used motor oil shows a lot thicker and sludgy in conventional oil vs. synthetic oil, given the same amount of wear. Synthetic oil is by far better for performance. It protects the engine due to lower levels of friction. Additives help clean the engine of deposits. And, fewer impurities mean it burns cleaner, thickens far more slowly, and has fewer deposits to start.
"According to industry tests, synthetic oil engines perform 47% better than engines using conventional motor oil." - AAA

The benefits of synthetic oil vs conventional oil:
• Fewer emissions
• Better fuel and oil economy
• Increased engine protection and wear from lower friction
• Longer intervals between oil changes
• Reduced engine drag from greater resistance to thickening
• Oil effectiveness/quality is more predictable and uniform
• Better all-weather protection
• Quicker engine start time
• Helps clean engine sludge and deposits
Synthetic oil is generally considered the best oil. It is designed for performance. However, that same manufacturing process makes it more expensive.
The real deal of synthetic oil vs. traditional oil:
• Better gas mileage won’t be an obvious difference to your short-term budget
• The added engine protection may save costs overall
• Synthetic oil is 6x – 10x the cost of traditional oil
• Switching to synthetics can clean deposits that are plugging leaks (You really shouldn’t have bad seals in the first place)
• You can switch back and forth between synthetic and traditional oil without consequence
• All cars benefit from the additives in synthetic oils
How to Choose the Best Motor Oil for Your Car
If you can afford it, choose a full synthetic oil. It is the best oil for any engine. Synthetic oil cuts down the hassles or oversights related to more frequent oil changes and deposits.
If synthetic oil is too expensive, go with a blend or rotate between a full synthetic and non-full synthetic every other oil change. Changing car oil will not damage your vehicle. Keep a record to remember the mileage, next oil change date, and type of oil.

Refer to your owner’s manual or look up the:
1. Viscosity grade
2. Oil specification
At Vaal Autonostics we will provide advice on the best oil for your specifications.
