Is Synthetic Oil Really Better Than Conventional?

-

 According to the experts at AMSOIL INC., synthetic oil is now widely accepted as superior to conventional oil, making it a preferred choice for consumers and vehicle manufacturers. While they both serve the same fundamental purpose – reducing friction and wear – synthetic oil is engineered to deliver enhanced performance and protection.

One of the most notable benefits of synthetic oil is its molecular and composition uniformity. Unlike conventional oil, which is refined from crude oil and contains natural impurities and inconsistent molecule sizes, synthetic oil is chemically engineered to have a more consistent molecular structure. The uniformity of synthetic oil allows it to change less in viscosity over a wider range of temperatures, aka, the oil’s viscosity index. A higher viscosity index can help deliver superior film strength for better protection under stress and flow more readily and efficiently to protect critical engine components better and faster.

Temperature stability is another major advantage of synthetic oil in both high and low temperatures. In cold conditions, it’s lack of impurities and waxes help it flow more easily, ensuring quicker engine starts and immediate protection. In high-heat environments, synthetic oil resists evaporation, thermal shear and oxidation better than conventional oil.

Synthetic oils also offer superior engine cleanliness. By containing fewer impurities
and resisting oxidation, synthetic oils help prevent sludge formation and deposit buildup. This keeps engine components clean, which helps extend engine life and retain performance and efficiency.

Another technical benefit is reduced oil consumption and longer intervals between oil changes. Because synthetic oil is more stable and durable, it doesn’t evaporate or degrade as quickly as conventional oil. This means fewer top-offs and extended oil change intervals, which can save time and money over the life of a vehicle.

Synthetic oil may come at a higher upfront cost, but its technical advantages make it a worthwhile investment for many who seek optimal engine health and performance.

AMSOIL Synthetic Motorcycle Oil is Engineered for Extremes

  Modern motorcycle engines are highly refined and benefit from specifically engineered lubrication. For example, engines that spin up to 10,000 rpm or higher can cause oil to foam, reducing its ability to protect engine components. Motorcycle oils usually serve dual purpose as clutch lubrication and the shearing transmission forces can also reduce an oil’s lubricating ability, leading to notchy shifting. Additionally, touring and adventure bikes are built for long, cross-country trips that benefit from extended drain intervals. And the increased heat generated by compact, high-performance engines can rapidly accelerate oil breakdown, leading to deposit formation that robs motorcycle engines of efficiency and power. Protection and Performance The advanced technology in  AMSOIL Synthetic Metric Motorcycle Oil  is specifically engineered to deliver maximum performance to prevent oil breakdown under extreme heat and pressure. It promotes smooth,   consistent shifting an...

How Exhaust Power Valves Improve Two-Stroke Performance.

  Restore your lost engine power. All engines draw air into the cylinder for combustion and expel the spent gases through an exhaust system. Exhaust power valves improve two-stroke engine performance by managing exhaust-port timing to maintain optimal throttle response and power delivery at any engine speed. Power valve inserted in the right exhaust port. Why exhaust power valves matter. all exhaust ports increase air velocity, which translates into improved power and throttle response at low rpm. However, small ports cannot move enough air as engine speeds increase, leading to reduced high-rpm performance. In other words, a narrow exhaust port will be more powerful launching the machine from a stop but lack top-end power. Large exhaust ports create the opposite effect, reducing low-rpm air velocity, throttle response and power, but increasing top-end power. To solve this problem, engineers designed variable valves for two-stroke exhaust ports that change size relative to operating...
