Is Synthetic Oil Better for High Mileage Cars?

If you have a high-mileage car, you may want to consider using synthetic oil. Synthetic oil is a popular engine oil choice for high-mileage cars because it helps keep them running smoothly. It also protects your engine against wear and tear, which is important if you’re driving a lot of miles.

Is High Mileage Synthetic Oil Worth It?

You know that synthetic oil has a higher level of performance than regular oil, but do you really need to go with synthetic oil? The answer is “yes!” Although you might know that synthetic oils outperform conventional oils, you might not know why. Synthetic oil does not contain impurities and molecular irregularities characteristic of conventional oils. Synthetic oils’ uniform, structural molecular structures provide them with exceptional properties that endow them with optimal performance and wear protection; when combined with other key attributes, you create an automotive lubricant that lowers your vehicle maintenance expenses.

How Long Does Synthetic Oil Last?

If your car runs on conventional oil, it can last up to 3,000 miles between oil changes. If you go with synthetic oil, you can get up to 25,000 between oil changes. This is because synthetic oil has a higher level of performance than regular oil.

What Is The Best Synthetic Oil?

AMSOIL Signature Series Synthetic Motor Oil is considered by many enthusiasts and professional engine builders to be the best high-mileage synthetic oil. Signature Series Synthetic Motor Oil offers 75 percent more engine protection than required by a leading industry standard, extending the life of vital components including pistons and cams. Its strong fluid film keeps metal surfaces separated while its powerful anti-wear additives reduce wear in metal-to-metal contact areas for maximum efficiency.

Protects Pistons from Low-Speed Pre-Ignition

We armed Signature Series with an advanced detergent system to protect vital engine parts like pistons and connecting rods. Most new engines feature gasoline direct injection (GDI), often combined with a turbocharger to boost power and improve fuel economy. These new technologies pose significant challenges to motor oil, one of which is the advent of low-speed pre-ignition (LSPI). LSPI is the spontaneous ignition of the fuel/air mixture prior to spark-triggered ignition. It occurs in today’s advanced engines and is much more destructive than typical pre-ignition. Signature Series provided 100 percent protection against LSPI in the engine test required by the GM dexos1® Gen 2 specification.

Protects Turbochargers

The tremendous heat and stress turbos create can cause some oils to break down and form harmful bearing deposits through a process known as turbo coking. Over time, turbos can suffer reduced performance or fail altogether. AMSOIL Signature Series Synthetic Motor Oil handles heat so well that it protects turbochargers 72 percent better than required by the GM dexos1 Gen 2 specification. It enables modern engines to achieve their full potential and service life. Signature Series provides the ultimate protection against extreme heat and the harmful deposits that can plague turbochargers and features the high film strength needed to guard against accelerated wear.

Maximum Cleaning Power to Battle Sludge

AMSOIL Signature Series Synthetic Motor Oil has 50 percent more detergents to help keep oil passages clean and promote oil circulation. Its detergent and dispersant additives are so effective, Signature Series provides 90 percent better protection against sludge than required by a leading industry standard.

Easier Cold-Starts

Signature Series Synthetic Motor Oil does not contain paraffin (wax) and stays fluid in temperatures as low as -58ºF. Extreme cold causes other motor oil to thicken, starving vital moving parts of lubrication, accelerating wear, and even preventing vehicles from starting. Signature Series provides 66 percent better cold-temperature performance than conventional oil for easier starting, better fuel economy, improved oil flow, and reduced wear. 

Reserve Protection

AMSOIL Signature Series Synthetic Motor Oil provides reserve protection, allowing you to go up to 25,000 miles or one year (in normal service) between oil changes if you choose. Its unique synthetic formulation and long-drain additive system are inherently stable to resist oxidation and neutralize acids over longer periods. 

Signature Series is designed to deliver outstanding engine protection, cleanliness, and performance over extended drain intervals – guaranteed. It provides peace of mind so you can fit oil changes into your schedule, while also reducing vehicle maintenance and waste oil.

Limiting Oil Consumption

Signature Series has a uniform molecular structure that limits evaporation and keeps it where it’s needed most – protecting your engine. Volatility (burn-off) occurs when oil gets hot, causing lighter molecules to burn off or evaporate. Signature Series falls far below the API limit for volatility, reducing the need for frequent oil top-offs and limiting vehicle emissions.

In conclusion, synthetic oil is better for high-mileage cars because it helps to keep the engine clean and free of sludge. It also helps to protect the engine from wear and tear, which can lead to longer engine life. It also lasts longer than conventional oil, so it is a more economical choice in the long run. If you have a high-mileage car, consider switching to synthetic oil to help keep it running smoothly.
