Most Slinger drivers are aware that manufacturers have service intervals for your car . The engineers that design our vehicles have tested the various systems and components to meet durability and safety standards. Some of these standards are self-imposed and others, like those for emissions components, are government mandated. The maintenance schedules are designed to achieve the standards. Think of the benefits of following recommended intervals as falling into three general categories: Protection, Efficiency and Safety.  Protection . Let’s start with motor oil. First of all, the engineers recommend a particular weight and type of motor oil. All of their oil change recommendations assume using the proper motor oil. Motor oil contains detergents and other additives that clean the engine and provide corrosion resistance. Over time, the additives are depleted. The oil also becomes contaminated by water, dirt and combustion gases. Extending your interval beyond the recommendation means that your engine will be operating without the full protection of fresh motor oil. It also means that sludge can form in contaminated oil and clog up passages in the engine, starving parts from needed lubrication. Efficiency . Some Slinger services are designed to keep automotive systems operating efficiently. For example, the fuel system gets clogged up with gum and varnish from the fuel. Fuel doesn’t flow efficiently which reduces fuel economy. A fuel system cleaning restores the fuel system’s efficiency and increases your gas mileage. Safety . Your brakes are obviously one of the most important safety systems on your vehicle. The has scheduled brake pad replacement as well as power brake fluid drain and replacement intervals. Because brakes are so important, a brake inspection is also on the schedule to head off problems before they result in an accident. Check your owner’s manual for recommended service schedules or talk with your friendly and knowledgeable Joe’s Slinger Service . You may be surprised to learn that various inspections may be on your list of factory recommendations. These inspections are usually at major intervals like 24,000 miles or 40,000 kilometers. They’re designed to uncover important parts that may be close to failing. Your owner’s manual can tell you when to change your oil, but it can’t tell you that you have a radiator hose that’s bulging and about to burst. For that you need a technician. These scheduled inspections are in addition to the multi-point inspections done with a full-service oil change at Joe’s Slinger Service.

When your car won’t start, the battery suddenly becomes the most important part of your vehicle. And when it’s time to replace it, many drivers are faced with a choice: grab the cheapest battery available or invest in one built for long-term reliability. At first glance, a budget battery from a big-box store like Walmart may seem like the obvious choice. But there’s more to the story than upfront cost. The Truth About Budget Batteries Budget batteries are designed to do one thing: start your car at the lowest possible price . For some drivers, that’s enough. These batteries are generally best for: Older vehicles with minimal electronics Light, short-trip driving Drivers who don’t mind replacing a battery more frequently While they can work, they often have: Shorter overall lifespan Less consistent cold-weather performance Limited reserve capacity for accessories and electronics That’s why many budget batteries fail sooner—especially in extreme temperatures or vehicles with modern electrical demands. Why We Choose ACDelco Batteries Today’s vehicles rely on far more than just a starter motor. From infotainment systems and safety features to remote start and stop-start technology, modern cars demand strong, consistent power . ACDelco batteries are built with higher-quality internal components designed to: Deliver stronger cold-cranking performance Handle higher electrical loads Last longer under real-world driving conditions Provide dependable warranty coverage In short, they’re engineered for reliability , not just price. Cost vs. Value: What Really Saves You Money? A lower-priced battery may save money today—but if it needs to be replaced sooner, struggles in winter, or leaves you stranded, that “deal” quickly disappears. A quality battery: Reduces the risk of no-start situations Lasts longer, meaning fewer replacements Performs better year-round Gives peace of mind every time you turn the key That’s why we don’t recommend batteries based on price alone. We recommend them based on what keeps our customers driving with fewer problems . Our Recommendation If your vehicle has modern electronics, sees extreme temperatures, or you simply want fewer battery issues, an ACDelco battery is the smarter long-term choice . We install batteries we trust—because your vehicle’s reliability matters to us. If you’re unsure which battery is right for your vehicle, stop by or give us a call. We’re happy to help you choose the option that fits your driving needs and keeps you on the road.

Preventive Maintenance Can Save You Thousands Most people think car problems come out of nowhere—but the truth is, many major repairs start as small, preventable issues. The one thing we wish every customer knew? Preventive maintenance matters more than fixing breakdowns. Small Problems Rarely Stay Small That tiny oil leak. That squeak when you brake. That warning light you’ve been ignoring because the car still “drives fine.” These are your vehicle’s early warning signs. Catching issues early usually means: Less expensive repairs Fewer breakdowns A safer, more reliable vehicle Longer vehicle life Waiting often turns a simple fix into a costly repair. Your Car Doesn’t Break Overnight Most major failures—engine damage, transmission problems, brake failure—happen because something small was overlooked over time. Regular inspections, oil changes, tire rotations, and fluid checks allow mechanics to spot issues before they become emergencies. Preventive Maintenance = Peace of Mind Staying on top of maintenance helps you: Avoid surprise repair bills Reduce stress Improve fuel efficiency Keep your family safe on the road At Joe’s Slinger Service , we believe honest communication and routine maintenance are the best tools for keeping your vehicle running its best. The Bottom Line If there’s one thing we wish every driver understood, it’s this: Preventive maintenance is always cheaper than reactive repairs. Your car talks to you—you just need someone who knows how to listen.
