Oil Change & Service in Marinette, WI

Oil does three things for your engine. It acts as a lubricant for all the moving metal parts so they don’t damage one another. Second, the oil flows through the engine and cools it prevent any overheating issues. Third, oil prevents carbon deposits from building up on and damaging the cooler parts of the engine.

• The Oil Looks Dark or Dirty: Fresh oil is a clear, golden-brown color. Over time, it darkens due to contaminants and engine byproducts. If you notice particles or a gritty texture, it's time for an oil change.
• Your Engine Sounds Louder: Oil lubricates the engine’s moving parts. When it gets too old or dirty, friction increases, causing your engine to run louder than usual.
• The Check Engine Light Stays On: A persistent check engine or oil change light is a clear warning that your oil needs attention. Ignoring it could lead to serious engine problems.
• Rapid Oil Level Drops: Engines naturally consume some oil over time. However, if the level is dropping too fast, don’t just top it off—check its color and consistency. If it’s thick, dark, or sludgy, a full oil change is necessary.

The thickness and/or the weight of the oil. This determines how fast or slow the oil will break down while running through the engine of your vehicle. Synthetic oil also gives you better engine performance and improved fuel economy.

Vehicles have made so many advances in recent years that it's possible to go longer between oil changes than you could say, twenty years ago without harming your engine. However, you should follow the recommendations in your owner's manual for oil change frequency based on your model and driving conditions.

GM oil change recommendations differ depending upon driving conditions, as well as model and year. If if the majority of your driving time is spent in the following conditions, you should have your oil changed more frequently:

• Extensive idling or in stop-and-go traffic
• Cold weather, less than 10 degrees
• Extreme heat, more than 90 degrees
• Extreme humidity
• Repeated short-distance trips of less than five miles
• Towing a trailer or hauling heavy cargo

The majority of GM vehicles are equipped with the Engine Oil Life System, which has made the 3,000-mile oil change obsolete. Depending on how old your vehicle is, your driving habits and the road conditions, vehicles with today’s advanced engines can go much longer than 3,000 miles between oil changes. Always be sure to check your engine oil level regularly, even with the Engine Oil Life System to avoid damage.
