Signature Series Best Synthetic Motor Oil

What Is The Extra in Signature Series Compared to Ordinary Motor Oil?

The foundation of an extraordinary synthetic motor oil lies in its superior ingredients. It’s often asked, “Which synthetic oil is best?” For more than 50 years, the answer has been AMSOIL® Signature Series. Since the beginning in 1972, this line of synthetic motor oil has been the leader, bringing the first API-qualified synthetic oil to the market and never letting up since. What you get today is still the highest quality formula, and AMSOIL still backs the Signature Series motor oils with a 40,000km/ 1-year rating. Bar none… it’s the finest oil change you can buy.

You might’ve heard a little story from 1998. Mobil® took Castrol® to court over their looser definition of ‘synthetic.’ Like most blending companies, their base stock began with conventional oil rather than pure chemicals. That lawsuit was unfruitful, and Mobil soon joined Castrol in producing a lower-quality product to compete.

Unlike the competition, AMSOIL continues to use pure base oils for its Signature Series motor oil lineup. While it might be called ‘over-engineered,’ that’s exactly how we like it. It’s for those who want the absolute best synthetic oil change, no exception.
