5W-40 is the grade for winter and summer being a multigrade so 5W relates to viscosity in winter and 40 the grade it will cope with in summer. You are unlikely to notice any difference in a 5W-30 and a 5W-40. the latter will be marginally better to keep in grade. All multigrades lose grade after time due to various reasons, primarily the products of combustion. All multgrades these days are excellent. You may even see 0W-50 grades in more costly oils.

This vehicle can use both grades of oil, so there should be no issue using 5w/40.

Check the spec in your manual and see what it recommends. You are looking for a number such as this 502.001 or something like these ACEA A3/B4, A3/B3, C3, API SN/CF or
GM LL-A-025 or GM LL-B-025 specified products were originally required. All oils carry a specific code of the manufacturers. I am sure that the Halfords oils will caryy your correct codes.

Question
Is this different to the diesel version?
You supplied this in error and I have filled my 110 JTD Fiat Multipla engine with it. Do I have to replace it? The old 5W/40 oil used to say suitable for petrol or diesel.

In this case Halfords 5W/40 Fully Synthetic Oil should be fine for your Fiat Multipla JTD as it meets the appropriate specifications for the vehicle. There should therefore be no need to drain the engine and refill it with the diesel version.

more information is needed here as there are quite an array of engines for the Fabia. Check the hand book and see the specification recommended. It will say the grade, possibly, but more likely a series of letters and numbers. Check that the oil you are buying is to that spec. Many oils are developed to car makers individual requirement. Diesels with DPF filters need Longlife oils (available from Halfords)

This, like almost every 5Wxx oil on the market at present is based on hydrocracked base stock. PAO is only needed for extreme low temperature work (below -35 deg C) and hydrocracked stocks are capable of meeting the highest levels of current industry and OEM performance.

"Yes Halfords oil is supplied by a subsidiary of Exxon Mobil." However this does not mean it is supplied by mobil or advertised under the mobil label.
