The Renault F3P 758 is a 1,721 cc, inline‑four naturally aspirated petrol engine produced between 1992 and 1996. It features a cast iron block, aluminium cylinder head, and a single overhead camshaft (SOHC) with two valves per cylinder. Output was typically 79 kW (107 PS), with torque peaking at 145 Nm, providing responsive performance for its class.
Fitted primarily to sportier variants like the Clio 16S and Laguna 1 RT, the F3P 758 was engineered for a more spirited drivin…
Production years 1992–1996 meet Euro 1 standards (VCA UK Type Approval #VCA/EMS/5679).
The Renault F3P 758 is a 1,721 cc inline‑four naturally aspirated petrol engine engineered for sporty compact and family hatchbacks/estates (1992-1996). It combines a robust cast iron block with a simple SOHC 8-valve design to deliver linear, rev-happy power. Designed to meet Euro 1 emissions standards, it prioritized driver engagement and mechanical simplicity.

The Renault F3P 758 was used across Renault's Clio 1/Laguna 1 platforms with transverse mounting. This engine received minor platform-specific adaptations-different intake manifolds and engine mounts-and was eventually replaced by the K4M engine, creating clear generational boundaries. All adaptations are documented in OEM technical bulletins.
The F3P 758's primary reliability risk is camshaft lobe wear, with elevated incidence in high-mileage or infrequently serviced engines. Renault workshop data indicates this is a known failure mode for engines over 180,000 km with poor maintenance history, while general owner feedback highlights it as a critical concern for neglected units. Regular oil changes and using the correct specification oil are paramount to prevent costly internal damage.

The most common questions about engine codes, what they mean, how to find them and how this database works
The F3P 758 can be very reliable long-term, but it demands diligent maintenance. Its Achilles' heel is camshaft lobe wear, which is almost always caused by poor oil maintenance. With strict adherence to oil change intervals using the correct 10W-40/15W-40 oil, it can easily surpass 200,000 km. Neglect, however, can lead to expensive repairs.
The most critical issue is camshaft lobe wear, followed by the common F3P problems like broken exhaust manifold studs, worn timing chain tensioners, and leaking rocker cover gaskets. These are well-documented in Renault service manuals. The camshaft issue is specific to this higher-performance variant and is maintenance-related.
The F3P 758 was the engine for the sportier models of its era. It was primarily used in the Renault Clio 16S (B/C57) and the Renault Laguna I RT (B56) between 1992 and 1996. It was the top-tier naturally aspirated petrol engine for these platforms before the K4M arrived.
Yes, modest gains are achievable. Common upgrades include a performance exhaust, a high-flow air filter, and ECU remapping, which can yield an extra 5-10 kW. More significant power increases are limited by the 8-valve head. Its robust bottom end makes it a good candidate for mild tuning if the camshaft is in good condition.
Fuel economy is typical for a 1.7L performance engine of the early 90s. In a Renault Clio 16S, expect around 9.0 L/100km (31 mpg UK) in combined driving. Highway cruising can be around 7.0 L/100km (40 mpg UK), while aggressive city driving will push consumption to 11-12 L/100km (23-25 mpg UK).
No. Like the F3P 706, the F3P 758 is a non-interference engine. If the timing chain were to break or jump, the pistons and valves will not collide. This is a major advantage, as it prevents catastrophic engine failure from a timing issue.
Renault mandates a mineral or semi-synthetic 10W-40 or 15W-40 engine oil meeting ACEA A3 specification. Using the correct oil is absolutely critical for this engine to prevent camshaft lobe wear. Full synthetic is not necessary. Change the oil and filter every 10,000 km or annually, whichever comes first.
