Looking for oil change recommendations for your 1985 GMC G1500? Turn to Firestone Complete Auto Care! Our expertise goes beyond tires. We know all about motor oil, too. After all, like our maintenance technician Brianna says, “Oil is the blood of the engine. It’s the #1 thing you can do for your car.”
GMC recommends having your 1985 GMC G1500’s motor oil changed at regular intervals. Check out mileage and month info for your G1500 in the above table. No matter the mileage, your G1500 may need its oil changed ASAP if your check engine light is on, you hear knock knock knock coming from the engine, smell oil inside the vehicle, or see an excess amount of vehicle exhaust. You might need an oil change more frequently than what’s recommended by GMC if you regularly haul heavy loads, drive in dusty terrain, enjoy off-roading, or go at low speeds on long distance trips. In general, being extra-diligent about oil changes won’t damage your GMC G1500. In fact, more frequent oil changes give our technicians more opportunities to catch and alert you to any issues, like worn brake pads or a weak battery.
Whether it’s synthetic, conventional, or a blend of both — your local Firestone Complete Auto Care has the right oil for your GMC G1500. GMC has most likely outlined either synthetic or conventional as the ideal engine oil for your 1985 G1500. Motor oil helps lubricate the engine’s moving parts, maintain proper engine temperature, and prevent harmful substances from accumulating in the engine. During your oil change service, one of our techs will change your G1500’s oil, replace and recycle your used oil and filter, check all of your other filters, top-off essential fluids, and perform a free inspection on the rest of your vehicle. You can drive with confidence knowing that we look out for you and your G1500 by taking into account your driving preferences, and mileage.
