What’s the best choice for your vehicle?
When it comes to taking care of your engine and maximizing your car’s efficiency, it’s not just how you drive — it’s also the fuel you choose. At Alas Estaciones, we offer two types of high-quality diesel designed for different needs: Diesel Plus and A‑Diesel. Both improve performance, protect your engine, and reduce fuel consumption — but which one is right for you?
Here’s a breakdown of their differences, technical benefits, and how to pick the best option for your vehicle.
What is Diesel Plus?
Diesel Plus is our standard high-quality fuel, enhanced with additives that:
-
Improve engine lubrication, reducing internal wear.
-
Help keep injectors clean, optimizing combustion.
-
Enable smoother cold starts.
-
Reduce fuel consumption by 1 % to 2 % compared to regular diesel.
It’s ideal for everyday diesel vehicles: cars, vans, SUVs, and light trucks. If you make short trips or drive regularly, Diesel Plus is a reliable, efficient, and economical choice.
What is A‑Diesel?
A‑Diesel is our premium version, designed for those who want superior performance or own more demanding vehicles. It features an advanced formula with specific additives that:
-
Provide greater lubrication — perfect for modern, high-pressure engines.
-
Deep-clean the injection system, preventing buildup and extending engine life.
-
Enhance performance under extreme conditions (cold, heat, prolonged use).
-
Offer up to 4 % fuel savings thanks to more efficient combustion.
It’s perfect for new vehicles, sports cars, industrial use or long-distance travel — and for anyone who wants to get the most out of their engine.
