There are various oil brands that are more powerful and gives a guarantee of 75000 km claiming that additives help reduce engine wear and provide anti-aging benefits. Various auto mechanic repair shop tells that some oils may be more beneficial than others because they contain conditioners purported to rejuvenate seals to prevent or stop oil leaks, a common ailment in engines with a lot of miles on them. Internal seals and gaskets become brittle and shrink as they age, allowing oil to flow by.
Sometimes this becomes visible as oil stains on a garage floor or as streaks of oil on lower engine parts. When valve guide seals wear, oil can leak into combustion chambers and the engine will literally start burning oil. With small leaks, blue smoke from burning oil may not be visible from the exhaust, but your oil level will probably drop below the full mark on a regular basis.
If you are using high-performance oil, it is good for your vehicle but never the less your car has 100,000 miles on it but it is still using little or no oil. Most of the auto mechanic repair shop tells that it is normal for an engine to consume some oil between oil changes from low to high. Every high-quality oil though makes similar claims that it does great things inside an engine and also improves power, engine life, and mileage.
Some auto mechanic repair shop recommend switching to a thicker oil such as 10W 30 instead of 5W 20 or using oil additives to stop oil leaks. As these oils are heavy but it similarly maintains the vehicle life. Thicker oil makes an engine harder to start in cold weather, reduces oil circulation around the engine and increases oil pressure, which means there will be more pressure trying to push the oil past seals and gaskets inside the engine.
Hence it is said that whether you use high power oil or low power, do change oil at regular intervals to maintain engine life and improve the health of the vehicle.
