Gasoline Direct Injection, or GDI, represents a significant shift in how modern engines deliver fuel to the combustion chamber. In a traditional port-injection system, fuel is sprayed into the intake port, where it mixes with air before entering the cylinder. This process has a secondary benefit: the gasoline, which contains various detergents, constantly washes over…
Why Your Engine’s Health Dictates Your Fuel Economy When I walk a driver out to their car after a service visit, the conversation often turns to how they can stretch their dollar at the pump. The reality is that your engine is a complex system of chemistry and physics, and even a small mechanical hiccup…
The Science Behind GDI Engines and Carbon Buildup Gasoline direct injection, or GDI, has become the standard for modern efficiency, but it comes with a specific mechanical quirk that most drivers don’t realize until their engine starts acting up. In a traditional port-injection engine, fuel is sprayed behind the intake valve, which effectively “washes” the…
Imagine for a moment that your vehicle’s engine is a living, breathing heart. In this analogy, engine oil isn’t just a lubricant—it is the very blood that keeps that heart beating. Here at Newton Nissan of Gallatin, we see thousands of vehicles every year, and if there is one universal truth we’ve learned, it’s…
