Read the articleElectricity vs. Gas vs. Diesel: The Real Cost per 100 km
Summary: Electricity vs. Gas vs. Diesel (Cost per 100 km)This article breaks down the real cost of driving 100 kilometers based on average consumption cycles and market prices:Home EV Charging (Off-Peak Rates): The undisputed financial winner. Consuming $17 \text{ kWh/100 km}$ at an off-peak rate of €0.20/kWh brings the final cost down to just €3.40.Highway EV Charging (Fast Charger): Using ultra-fast public charging networks (€0.50/kWh) drastically inflates the bill, raising the cost to €8.50 per 100 km.Diesel: Thanks to its high thermal efficiency ($5.2 \text{ L/100 km}$ at €1.75/L), it maintains a highly competitive cost of €9.10, making it a great economic rival to highway fast charging for long-distance drivers.Gas (Petrol): The most expensive daily option, coming out to an average of €12.03 per 100 km ($6.5 \text{ L/100 km}$ at €1.85/L).Tankly's Verdict: Electric cars are the absolute best choice for daily commuters who can plug in at home, running up to 4 times cheaper than gas. However, for drivers who spend most of their time cruising on long highway journeys, Diesel remains an incredibly practical and financially sound option.
Read the articleWhy Is Fuel So Expensive on the Highway?
This article explains why fuel prices skyrocket on highways compared to city stations or supermarkets. The steep price difference is driven by three main factors: heavy concession fees (rent) paid to highway management companies, strict operational guidelines (compulsory 24/7 opening hours and the maintenance of free public services like clean restrooms and showers), and a captive customer base with no immediate competing stations nearby. To avoid the highway premium, Tankly advises drivers to always fill up before passing the toll booths, or to use the price comparator to locate budget-friendly supermarket stations just a two-minute drive off an upcoming highway exit.
Read the articleSupermarket vs. Brand-Name Gas Stations: Is the Quality Really the Same?
Summary: Supermarket vs. Brand-Name Gas StationsThis article settles the debate between buying budget fuel at supermarkets (like Costco or Walmart) and premium fuel at major brand-name stations (like Shell, Chevron, or Exxon). The Same Core Fuel: All fuel originates from the exact same regional refineries and must strictly comply with mandatory national standards. Your car will not break down simply from using supermarket gas. The Secret is in the Additives: The major difference lies in the proprietary blend of chemical additives injected by brand-name stations. These include detergents, anti-corrosion agents, and friction modifiers designed to clean and protect your engine over time. Supermarkets generally stick to standard fuel with minimal required additives to keep prices low. The Tankly Expert Verdict: To balance your budget and your engine's health, use the "1-in-4 rule". Fill up at a cheaper supermarket station three times in a row, then use a premium brand-name station for your fourth tank to flush out any carbon deposits and keep your injection system clean.

In short: Quick wins to lower your fuel gauge right away: Anticipation: Look far ahead to let the car coast instead of coming to a dead stop. Re-accelerating a rolling car burns three times less fuel than launching from a standstill. Shift Early: Shift up before 2,000 RPM (gasoline) or 1,800 RPM (diesel) to keep the engine from working too hard. Engine Braking: Lifting your foot off the gas while in gear completely cuts fuel injection (0.0 MPG), unlike coasting in neutral which still burns gas to keep the engine idling. The Speed Factor: Dropping your highway speed from 80 mph to 70 mph cuts fuel consumption by 10%, costing you only about 4 minutes over a 60-mile trip. Hidden Savings: Beyond saving hundreds of dollars a year on fuel, smooth driving can double the lifespan of your brake pads and tires.
