Consider the recommended oil change intervals for Amsoil or Liqui Moly motor oil to ensure optimal engine performance and longevity.

AMSOIL’s extended-drain synthetic motor oil offers significantly longer intervals before an oil change, lasting up to 25,000 miles or one year. This extended interval can be beneficial for reducing maintenance frequency and saving time and money.

Then again, Liqui Moly’s oil change intervals may vary depending on the specific product, driving conditions, and manufacturer’s recommendations. While Liqui Moly also offers motor oils with extended intervals compared to conventional oils, these intervals are often shorter than AMSOIL’s.

No 06: Sustainability and Environmental Impact

Both brands prioritize sustainability and have taken steps to reduce their environmental impact. But there are some small differences in approach.

AMSOIL focuses on responsible sourcing and manufacturing practices to minimize its ecological footprint. They’ve implemented measures to reduce waste, conserve energy, and control emissions throughout their production process.

On the other hand, Liqui Moly is committed to reducing its environmental impact and ensuring its products meet eco-friendly standards. They strive to develop biodegradable motor oils with low toxicity levels. And have worked to reduce their carbon emissions, saving both energy and money.
