Frequently asked questions
Which Alfa Romeo Giulietta engine is the most reliable?
1.4 TB MultiAir (turbo) — Maint. Sensitive verdict. The 1.4 TB MultiAir turbo (105–170hp) is the volume Giulietta petrol — characterful and willing, but it asks for care. The MultiAir electro-hydraulic valve unit (the 'brick' on top of the head) is sensitive to oil quality/level and can fail expensively, the timing chain and turbo want clean correct-spec oil, and some examples use oil. A documented, oil-disciplined car is rewarding; an unknown-history one that's been neglected can get costly. Buy on service history.
