1990 Mitsubishi Sigma Oil Change

Looking for oil change recommendations for your 1990 Mitsubishi Sigma? Get the advice you need at Firestone Complete Auto Care! We are experts in car care — not just tires. We know the ins and outs of motor oil, too. After all, "Oil is the blood of the engine. It's the #1 thing you can do for your car," says our maintenance technician, Brianna.

Your 1990 Sigma’s oil should be changed according to Mitsubishi’s recommended oil change intervals. Check out mileage and month info for your Sigma in the above table. Outside of Mitsubishi-recommended oil change intervals, your Sigma may need an oil change if your check engine light is on, you hear knock knock knock coming from the engine, smell oil inside the vehicle, or notice excess vehicle exhaust. You may also need an oil change more frequently than Mitsubishi recommends if you haul heavy loads, frequent dusty roads, go off-roading a lot, or go at low speeds on long distance trips. Generally, getting more frequent oil changes won’t hurt your Mitsubishi Sigma. In fact, every oil change is an opportunity to diagnose and treat any other issues, such as bad brakes or a failing battery.

Whether you need high mileage oil, synthetic oil, or conventional oil, you'll find the right 1990 Mitsubishi Sigma motor oil at Firestone Complete Auto Care. Mitsubishi has recommendations as to whether conventional or synthetic oil is the ideal engine oil for your 1990 Sigma. Motor oil reduces friction between engine components, regulate engine temperature, and keep harmful substances from building up inside the engine. In an oil change service, an auto technician will change your Sigma’s oil, replace and recycle your used oil and filter, inspect the rest of your car’s filters, top-off essential fluids, and visually inspect the rest of the vehicle. You can rest assured knowing that we seek to do what’s best for your Sigma by considering your driving preferences, and mileage.
