MidShire Synth-X Ultra 0W-40

Product Overview

MidShire Synth-X Ultra 0W-40 is a fully synthetic, high-performance engine oil formulated to ACEA A3/B4 and API SN/CF standards. It is designed for use in high-output petrol and diesel engines — including turbocharged, supercharged, and high-revving naturally aspirated units — where maximum protection and performance are required.

The 0W winter rating ensures rapid oil circulation from cold start, reducing wear during the critical warm-up phase. The 40-grade high-temperature viscosity delivers strong oil film protection under sustained high loads and temperatures. This product is suitable for vehicles with extended drain intervals where the manufacturer's specification permits.

Typical Applications

High-performance petrol engines — turbocharged and naturally aspirated
High-output diesel engines in passenger cars and light commercial vehicles
Vehicles used in demanding conditions — towing, track use, sustained motorway driving
Older European vehicles requiring ACEA A3/B4 specification
Vehicles where the manufacturer specifies a 0W-40 or 5W-40 synthetic oil
