So the 1.5 engine is not using a wet-belt? That could be a serious improvement if the engine is really more reliable than the 1.0 Btw are you referring to the 3- or 4-cyclinder 1.5 engine? I got confused from the specs I found Ford 1.5L EcoBoost Dragon Engine (3-cylinder) Ford 1.5L EcoBoost I4 Engine (4-cylinder)
The most reliable engine is the 2.0 GTDi in the Focus ST, if looked after they are very reliable 1.6 Petrol non turbo is OK but gutless, really gutless, turbo unreliable 1.5 4 cylinder is prone to failure, I have read, but no seen much evidenceI'm a Ford technician and I can tell you, that the 3.5 ecoboost is far more popular than the 5.0, and all the major problems I've seen in the 3.5 are due to lack of maintenance. Ford says 10,000, but from what I see, 10,000 even with full synthetic is too long and you'll run into cam phaser and timing chain concerns, as well as turbo concerns.Which is potentially more reliable/dependable motor the 1.0 or 1.5 Ecoboost for the III.1 (facelift) Ford Focus? I couldn't find any statistics on the internet, so I am reaching out for your experience. I am looking to buy a used 2015-2016 focus estate with max 90-100k KMs (not miles). FshO9N.
