Italian Tuneup: Myth or Engine-Saving Practice? Italian Tuneup Explained-Benefits for Modern Engines

Ever heard of the Italian Tuneup? This classic car practice has sparked debate for years. In this video, we explore its origins, how it works, and whether it benefits modern engines. Plus, we answer the burning question: How often should you redline your engine? Let’s dive into the history, science, and practical tips for using the Turin Tuneup to keep your car in top shape.

The Italian Tuneup originated in the carbureted engine era, where carbon buildup and fouled spark plugs were common. By driving at high RPMs over long distances, drivers would burn off carbon deposits, clean exhaust passages, and restore engine efficiency. Back then, it was a necessity, as spark plugs needed regular maintenance and carbon buildup could significantly affect performance.

Modern engines, however, have come a long way. Designed with precision and efficiency in mind, today’s engines feature advanced fuel management systems, direct injection, and longer-lasting spark plugs made of materials like iridium. So, is there still a place for the Italian Tuneup?

Surprisingly, yes! While it’s not as essential for modern cars, periodic high-RPM driving can still clean injectors, help manage carbon buildup in combustion chambers, and even clear soot in exhaust systems like diesel particulate filters (DPFs). The benefits are particularly noticeable in engines that are turbocharged or driven gently for extended periods.

But how often should you redline your engine? The answer depends on your car. For smaller turbocharged engines, occasional high-RPM driving (not necessarily at the redline) can keep things running smoothly. For larger engines, the need may be less frequent. It’s essential to warm up your car first, ensure the oil is at operating temperature, and never hold the engine at redline for long.

This practice isn’t about maxing out the rev limiter but exploring the upper RPM range to improve airflow, fuel injection, and overall performance. So, if your car feels sluggish or you’re prepping for a long journey, the Italian Tuneup could help.

I do a lot of three or four hundred mile trips with London driving inbetween. Most of the time the ML350 3.7 litres is running at about 2, 500. And I try to use Momentum 99 Super Unleaded. On the long trips I'll just do a brief burst at say 5, 000 revs - just two to three minutes. I also take off cruise control every ten to fifteen minutes to pull oil up into the engine.
Not sure if any of this helps? But as a 2005 it's now at 160, 000 miles and sounds very smooth. My guess is that twenty year old cars don''t like cheap unleaded.
