0W20 Fully Synthetic Engine Oil Fuel Efficient Chrysler MS-6395 Dexos 1

0W-20 Fully Synthetic Fuel-Efficient Engine Oil

Westway Oils 0W-20 fully synthetic engine oil is a low-viscosity lubricant formulated for petrol engines that require SAE 0W-20 and the specifications listed below. It supports rapid cold-start circulation, engine cleanliness and fuel-efficient operation while helping protect against wear, corrosion, oxidation and deposit formation.

This oil is particularly well suited to modern driving conditions, including short journeys, urban use and frequent stop-start traffic. Available in 5-litre and 20-litre sizes.

Specifications and performance levels

• SAE 0W-20
• API SN
• ACEA A1/B1
• GM dexos1
• ILSAC GF-5
• Ford WSS-M2C947-A
• Chrysler MS-6395

Typical applications

Suitable for Chrysler, Ford, Vauxhall and other petrol vehicles when the handbook requires SAE 0W-20 oil with one of the stated performance levels. Vehicle make alone does not determine compatibility; the exact specification in the handbook must match.

Key benefits

• Low-viscosity formulation supporting fuel-efficient operation
• Fast oil circulation during cold starts
• Helps minimise engine wear and oxidation
• Helps control sludge, deposits and corrosion
• Suitable for year-round use in typical UK conditions
• Fully synthetic formulation for consistent performance

Before ordering

Check the vehicle handbook or manufacturer service information for the required viscosity and specification. Do not select an engine oil solely by vehicle make, model or fuel type. If your vehicle requires a different Ford, GM, Chrysler, ACEA or API standard, choose an oil carrying that exact requirement.

Frequently asked questions

Is this oil suitable for every Ford, Chrysler or Vauxhall?
No. It is suitable only when the engine requires 0W-20 and a matching specification such as Ford WSS-M2C947-A, Chrysler MS-6395 or GM dexos1.

Can it be used in diesel engines?
Use it only if the diesel engine handbook explicitly lists a matching viscosity and specification. Many diesel engines require a different low-SAPS oil.

Which size should I buy?
Choose enough oil for the stated sump capacity plus any allowance required for the oil filter and future top-ups.
