- THE EXTRA MILE: Fuel, Oil, and Transmission Truths Every Driver Should Know. (2-14-26)

🎙️ Drive Radio: The Extra Mile — Additives, Myths, and Mechanical Truths What really helps your vehicle—and what’s just expensive hype? In this episode of https://Drive-Radio.com: The Extra Mile, host John Rush takes listeners deep into the world of automotive additives, separating proven maintenance from marketing myths. Are there truly “miracle” products that fix engines, boost fuel economy, or make fluids last forever? Or are some of these claims quietly costing you performance, longevity, and money? John explains why top-tier fuel matters, how inconsistent gasoline complicates diagnostics, and why buying quality fuel up front can prevent drivability issues later. He breaks down fuel additives that actually serve a purpose—and warns against pump add-ons and “repair-in-a-can” solutions that can damage engines or exhaust systems. The conversation shifts under the hood to engine oil, direct-injection engines, and cold starts, revealing why modern engines demand precise oil viscosity, regular service intervals, and high-quality filters. John also tackles common myths around extended oil change intervals and “lifetime” fluids—especially when it comes to automatic transmissions, which he describes as one giant hydraulic system that thrives on clean fluid. From fuel stability in classic cars to the real cost of deferred maintenance, this episode asks a simple question with big financial implications: Do you want to pay now—or pay later? If you want fewer surprises, lower repair bills, and a vehicle that lasts, this is an Extra Mile worth taking.
