When you peruse Mobil 1’s catalog, you realize that it has plenty of lubricants to match various needs, and they come at different prices.

Mobil 1 uses plenty of base stocks, from group I to V, explaining the price diversity. On the other hand, Amsoil products are pretty expensive, justified by their extensive use of high-grade group V base oils.

Still, on price, we can bring up the Amsoil vs. Mobil 1 vs. Castrol discussion. Here, Castrol is the victor with cheaper products without compromising quality. The downside of Castrol is its shorter drain intervals.

Mobil 1 Vs. Amsoil Performance

Performance is a crucial aspect to consider when picking ideal motor oil. Mobil 1 and Amsoil outdo one another regarding functionality, courtesy of their high-quality lubricants.
