Mobil Mobil 1 ESP X1 0W-30 Fully Synthetic Motor Oil — 6 Quart Pack, Low-Ash DPF-Friendly Protection

Mobil 1 121218-6PK ESP X1 0W-30 is a fully synthetic motor oil sold as a six-quart pack, engineered to support modern diesel and gasoline emission systems while delivering long-lasting engine protection.

This Mobil 1 ESP X1 0W-30 six-quart package supplies technicians, fleet operators, and car owners with a ready quantity of synthetic oil formulated for compatibility with diesel particulate filters (DPF) and gasoline catalytic converters (CAT). It replaces earlier Mobil 1 ESP formulas such as the 5W-40 and the prior 0W-30 versions, and is tailored to preserve emission-system efficiency without compromising wear protection, cold-start performance, or fuel economy in vehicles that specify low-viscosity synthetic oil.

How does this oil help emission systems last longer?

Mobil 1 ESP X1 0W-30 is formulated to be fully compatible with modern DPFs and catalytic converters, helping reduce deposits and ash buildup that can shorten component life. The low-ash technology and controlled additive package are designed to protect emission devices while maintaining engine cleanliness.

• Low-ash formulation to minimize particulate filter clogging
• State-of-the-art additive balance to reduce catalyst poisoning
• Engine-cleaning detergents to prevent harmful deposit formation

Is this oil suitable for both diesel and gasoline engines?

Yes — Mobil 1 ESP X1 0W-30 is engineered for use in a wide range of modern diesel and gasoline passenger vehicles that call for low-viscosity synthetic oils. Always confirm your vehicle manufacturer’s specification before use to ensure compatibility and warranty compliance.
