Oil Change FAQ

Oil Changes in Spokane

Keeping up to speed with routine oil changes is one of the simplest and best ways to protect your engine and extend the life of your Mitsubishi. At Arrotta's Mitsubishi in Spokane, WA, we'd like to address your most asked oil change questions—so you can cruise with confidence wherever life leads you.

How frequently should I have an oil change?

For all of the Mitsubishi vehicles, an oil change is recommended every 3,000 to 5,000 miles using conventional oil, and every 7,500 to 10,000 miles with synthetic oil. But your ideal schedule is totally your call and your vehicle, driving habits, and oil used. If you're unsure, our service center would be happy to review your owner's manual or vehicle history with you.

What is conventional vs. synthetic oil?

Conventional oil is derived from natural crude oil and is appropriate for everyday driving. Synthetic oil, on the other hand, is chemically formulated to deliver greater performance, flow, and protection of the engine—especially under difficult weather conditions like Spokane's winters or extended driving on sweltering summer days. Certain newer Mitsubishi vehicles are even designed to operate with synthetic oil.

How do I know if my vehicle needs an oil change?

Watch for signs like a light oil change or check engine light, gray or gritty oil on the dipstick, engine noise, or reduced performance. If your vehicle isn't running as smoothly as it used to, perhaps it's time to bring it in for service—perhaps even if you haven't yet reached the mileage milestone.

Can I switch from regular oil to synthetic oil?

Yes, you can switch to synthetic oil whenever you'd prefer. In fact, a lot of Mitsubishi owners prefer to make the switch for increased engine protection and more extended oil change intervals. Our service advisors can help you determine what is optimal for your vehicle and your driving habits in Spokane.

Why are regular oil changes important?

New oil lubricates the moving parts of your engine, reduces friction, prevents overheating, and cleans your engine. Neglecting regular oil changes can lead to sludge accumulation, decreased fuel efficiency, and ultimately damage to your engine. Oil changes are one of the most cost-efficient ways of ensuring your automobile performs well.

How long does an oil change at Arrotta's Mitsubishi take?

Most oil changes will take 30–45 minutes, depending on your vehicle and if you're adding other services. We aim to make your visit as quick and easy as possible—stop by and hang out in our waiting room or inquire about drop-off.

Do you use Mitsubishi-approved oil and filters?

Yes, we use top-quality oil and OEM oil filters approved by Mitsubishi. Whether you drive a Mirage, Outlander, Eclipse Cross, or any model, we have the right products to provide long-term performance.
