1.0, 1.2 and 1.4 Fire vs 1.6 and 1.8 Ecotec 16v: which engine is more reliable?
According to our risk index, the 1.0, 1.2 and 1.4 Fire carries less risk than the 1.6 and 1.8 Ecotec 16v: 20/100 versus 23/100 (both low risk). The 1.0, 1.2 and 1.4 Fire has no documented serious faults; the 1.6 and 1.8 Ecotec 16v has no documented serious faults.
The index (0–100) weights the severity and frequency of the three most serious documented faults. How it is calculated
Is the 1.0, 1.2 and 1.4 Fire reliable?
The 1.2 8v Fire is one of Fiat's simplest and most widespread petrol engines, with more than two decades in production and no serious or systemic faults documented. The sources consulted describe it as robust: its most-cited issues are isolated sensor failures (lambda sensor, crankshaft sensor), the ignition coil and somewhat high oil consumption at higher mileages; there is no pattern of timing belt breakage.[1][2][3][4][5][6]
See the 4 of the 1.0, 1.2 and 1.4 Fire faultsIs the 1.6 and 1.8 Ecotec 16v reliable?
The 1.6 and 1.8 16v Ecotec (Z16XER/A16XER, Z18XER/A18XER) that Opel fitted between 2005 and 2015 to the Astra H and J, Zafira B, Vectra C and Insignia A have a reputation as reliable naturally aspirated engines: the sources consulted document no serious faults or failure patterns, only minor problems such as ignition coils and, on the 1.8, leaks from the oil cooler or thermostat.[7][8][9][10]
