It probably doesn't matter, but if Ford allows the option, I'd choose 5w-30 for the 1.5L engine. Direct-injected, turbo engines like the 1.5 EcoBoost tend to dilute the engine oil with fuel, which in turn can permanently reduce the oil's viscosity. Having the added viscosity of a 5w-30 provides extra protection if fuel dilution occurs. When the engine pressure warning light flickers there is insufficient oil pressure. When this happens the engine should be stopped immediately to prevent serious engine damage. Being a 1.0 ECOboost the flickering oil pressure warning light will most likely be caused by a disintegrated wetbelt (timing belt). The rubber particles of the wetbelt 345. Name: Ray.

Although my Ecoboom is older (2012) the mileage is not too different to the time it originally failed, due to a serious oil pump strainer blockage (wet belt debris). 2. amandstu Discussion starter. 10 posts · Joined 2020.

Engine Code: JTDA/JTDB Sigma EcoBoost On the 1.0 Ecoboost engine, Ford incorprate a ‘wet belt’ system, where the cambelt runs in engine oil and is sealed in the unit. If you use oil of the wrong grade or viscosity then the belt won’t be getting properly lubricated. If this happens, the engine will simply cut out, with disastrous consequenc­es. My source of info states. 5w20 wss-m2c948-b or 5w30 Wss-m2c 913-C for all petrol Ecoboost except 1.0l (5w20 required) and Wss-m2c 913-C for all diesels. My source (bobstheoilguy.com) is market independent, so checking your owners manual is the key. Identical revisions of the same engine often use different oil in different territories. Oil light stays on for 1-2sec. Hello guys i am a new member here in the forum. I bought a new Ford Focus 1.0cc with the 125hp.The car has about 14.000km and lately i notice that in the morning the oil pressure light stays on for about one or two secs and then goes off. Because i know that oil (Castrol ecoboost 5w 20) is the blood of the engine tfTHK.
