The Renault F3R 728 is a 1,995 cc, inline‑four petrol engine produced between 1990 and 1996. It features a single overhead camshaft (SOHC) and 8 valves, delivering outputs around 79 kW (107 PS) and 158 Nm of torque. Its simple, robust design prioritized reliability and ease of maintenance for everyday drivability.

The Renault F3R 728 is a 1,995 cc inline‑four petrol engine engineered for compact and mid-size hatchbacks and sedans (1990-1996). It combines multi-point fuel injection with a single overhead camshaft to deliver adequate low-end torque for city driving. Designed to meet Euro 1 standards, it prioritizes mechanical simplicity and serviceability.

The Renault F3R 728 was used across Renault's Clio, 19, and Laguna platforms with transverse mounting. This engine received platform-specific adaptations-minor ECU mapping differences between models-and no significant facelift revisions during its production run. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
The F3R 728's primary reliability risk is exhaust manifold stud failure, a common issue across its production run. Renault workshop data indicates this is the most frequent cause for exhaust-related repairs. Thermal cycling in all climates makes using upgraded replacement studs critical during any repair.

The most common questions about engine codes, what they mean, how to find them and how this database works
The F3R 728 is renowned for its mechanical simplicity and robustness. With regular oil changes and basic maintenance, these engines can easily surpass 200,000 km. The main long-term concern is exhaust manifold studs, which are a known weak point but are inexpensive and straightforward to fix.
The most frequent issues are broken exhaust manifold studs, carbon buildup in the throttle body and idle air control valve causing idle problems, and coolant leaks from aging plastic components. Ignition system wear (distributor, plugs, leads) is also common as the engine ages.
The F3R 728 was primarily used in the first-generation Renault Clio (1990-1996), the Renault 19 (1990-1996), and the early Renault Laguna I (1994-1996). It was fitted to various trim levels like RN, RT, and RL.
Yes, but gains are modest due to its SOHC 8-valve design. Common modifications include a performance exhaust, air filter, and ECU chip remap, yielding around 10-15 additional PS. Significant power increases require internal modifications, which are often not cost-effective for this engine.
Fuel economy is reasonable for its era and displacement. Expect around 9.0 L/100km (31 mpg UK) in combined driving for a Clio or 19. Highway cruising can drop consumption to around 7.0 L/100km (40 mpg UK), while city driving may see figures closer to 11.0 L/100km (26 mpg UK).
No. The F3R 728 is a non-interference engine. This means that if the timing chain were to fail or jump, the pistons will not contact the valves, preventing catastrophic internal engine damage. This is a significant reliability advantage.
Renault originally specified a 10W-40 mineral or semi-synthetic oil meeting CCMC G5 standards. Modern equivalents meeting ACEA A3/B3 are perfectly suitable. A 5W-40 fully synthetic can also be used for better cold-start protection and extended drain intervals.
