Hello, road warriors and wheel enthusiasts! When it comes to keeping your vehicle in tip-top shape, two terms that often get tossed around are "tire balancing" and "wheel alignment." At first glance, they might seem like they serve the same purpose – after all, they both involve wheels, right? But before you let your eyes glaze over at the thought of yet another car care jargon lesson, let me break it down for you with a touch of humor.

This essential component is responsible for providing warm air to the cabin, ensuring a comfortable driving experience. However, a blocked heater core can cause significant issues.

In the evolving landscape of automotive fuels, ethanol has become a significant component. But what exactly is ethanol, why is it added to fuel, and what does its presence mean for your vehicle? Let’s dive into the details. What is Ethanol? Ethanol is an alcohol-based fuel additive derived primarily from corn or other plant materials. It’s often blended with gasoline to create what’s known as "gasohol." In the U.S., common blends include E10 (10% ethanol) and E85 (85% ethanol). The primary reasons for adding ethanol are to reduce greenhouse gas emissions, enhance octane levels, and provide a renewable alternative to purely fossil fuels. Why Add Ethanol? Ethanol helps to lower the overall carbon footprint of gasoline, as it's produced from renewable resources. Additionally, ethanol raises the octane rating of fuel, which can improve engine performance and efficiency. This blend also supports domestic agriculture and r ... read more
