There are a full range of Mobil™ engine oils suitable for different models of Vauxhall cars, including oils suitable for petrol engines and oils suitable for diesel & Vauxhall TDI diesel engines. For example, there are Mobil engine oils engineered to be suitable for Vauxhall Corsa models such as the Vauxhall Corsa SXi 1.4, and also engine oils engineered for Vauxhall Astra models such as the Vauxhall Astra 1.4i 16v VVT.
Mobil 1™ ESP 0W-40 is a fully synthetic low ash oil approved by General Motors for both petrol and diesel Vauxhall cars requiring the dexos2 oil standard. The dexos2™ standard is backwards compatible with the older GM oil specifications GM-LL-A-025 and GM-LL-B-025.
Fully synthetic oils such as Mobil 1 circulate around your Vauxhall engine more easily than traditional mineral oils, so your engine operates more efficiently. Mobil 1 also gets to work faster so your engine reaches peak operating efficiency quicker. Both of these benefits mean potentially improved fuel efficiencies that save you money on fuel.
Tests show that Mobil 1 can reach all moving parts of the engine 15 seconds faster than some conventional oils. Until your oil circulates fully, friction between dry parts of the engine will slowly reduce the life of the engine. Synthetic engine oils like Mobil 1 start circulating right away, protecting every moving part within the engine, and over time this can translate into savings in maintenance costs.
It is important to use the right oil in your car to comply with the Vauxhall / General Motors manufacturer specifications. Using the right Mobil 1 product during routine servicing and according to your vehicle's handbook will not affect the Vauxhall / GM manufacturer's warranty. You can obtain a recommendation by using the Mobil 'Which oil' tool and searching by make and model or car registration.
