Noticed my gas mileage started going down gradually. At first I thought it was just weather or maybe gas quality, but it kept dropping. Finally went in for a tune-up. Turns out my air filter was clogged, spark plugs were worn, and two tires were underinflated. After fixing all that – boom – mileage improved by 15%. For my truck, that’s a big deal. Over a year, that’s hundreds of dollars in savings. The crazy part? The whole tune-up cost less than what I was losing in fuel every month. The article I read after the fact explains exactly how small things like filters, tire pressure, and plugs all affect fuel economy:https://pickuptrucktalk.com/2025/07/why-regular-car-repair-can-save-you-thousands-in-the-long-run/ – great read for anyone watching their fuel bill.
