Looking for oil change recommendations for your 1998 GMC K3500? Get the advice you need at Firestone Complete Auto Care! We're experts in more than tires. We know the ins and outs of motor oil, too. We couldn’t put it better than our technician, Brianna. She likes to explain to customers that, “Oil is the blood of the engine. It’s the #1 thing you can do for your car.”
Your 1998 K3500’s oil should be changed according to GMC’s recommended oil change intervals. Check the interval for your vehicle mileage in the table above. No matter the mileage, your K3500 may need its oil changed ASAP if your check engine light is on, you hear engine knocking, smell oil inside the car, or see an excess amount of vehicle exhaust. You may also need an oil change more frequently than GMC recommends if you haul heavy loads, drive in dusty areas, enjoy off-roading, or drive at low speeds for long distances. In general, being extra-diligent about oil changes won’t damage your GMC K3500. In fact, every oil change is an opportunity to diagnose and treat any other issues, such as bad brakes or a failing battery.
Your local Firestone Complete Auto Care has the right 1998 GMC K3500 motor oil: either synthetic or conventional. GMC has specifically identified either synthetic or conventional as the ideal engine oil for your 1998 K3500. This oil helps lubricate engine parts, maintain proper engine temperature, and prevent harmful substances from accumulating in the engine. During an oil change, an auto technician will change your K3500’s oil, replace and recycle your used oil and filter, inspect the rest of your car’s filters, top-off important fluids, and perform a courtesy inspection on your entire vehicle. You can rest assured knowing that we seek to do what’s best for your K3500 by considering your driving style, and odometer.
Wondering if we carry the right motor oil for your GMC? We carry the best because your K3500 deserves the best. Check your owner's manual and talk with a technician to select the right GMC K3500 oil, whether it's Quaker State® Advanced Durability™ conventional oil, Pennzoil® High Mileage Vehicle® motor oil, Pennzoil Platinum® Full Synthetic motor oil with PurePlus™ Technology, or Shell Rotella® heavy-duty engine oil. There's a reason we carry these motor oil brands. They are tested and trusted. For example, when tested in taxi fleets across North America, Quaker State was shown to provide 2x more protection than the industry standard.  Pennzoil is another option. Pennzoil Synthetics are the most technologically advanced, fully formulated motor oils available and exceed current industry and manufacturer requirements. But don't forget about Shell Rotella for heavy-duty engines. It's specifically designed for diesel and gasoline engines that need to survive the toughest working conditions, and is uniquely strengthened to deliver heightened performance in extreme temperatures, increased wear protection, and better oxidation resistance.
