How Long Can You Wait Until Your Next Oil Change?

Wondering how long you can go without an oil change? Learn what happens if you don’t get an oil change, the signs of overdue oil, and why routine maintenance matters.

Your Subaru is built for adventure, but no matter where the road takes you, routine maintenance is key to keeping it running at its best. One of the simplest yet most essential services? Regular oil changes.

But life gets busy, and sometimes, that oil change appointment keeps getting pushed back. How long can you go without an oil change before it affects your car’s performance? And what happens if you don’t get an oil change for too long? Let’s dive in.

Why Oil Changes Matter for Your Subaru

Engine oil is more than just a lubricant—it helps protect your engine from excessive heat, wear, and contamination. Fresh oil keeps all the moving parts working smoothly, whether you’re cruising down the highway or tackling rugged trails.

Over time, however, oil breaks down and collects dirt and debris. When that happens, it loses its ability to properly lubricate your engine, increasing friction, overheating, and the risk of long-term damage.

Ignoring an oil change might seem harmless at first, but it can lead to major (and expensive) problems later on.

How Often Should You Change Your Oil?

The right oil change schedule depends on your Subaru model, driving habits, and the type of oil you use. Here’s a general guide:

• Older Subaru models: Every 3,000 miles
• Most modern Subarus: Every 6,000 miles
• Subarus using full synthetic oil: Every 10,000 miles or more

While these are standard recommendations, it’s always best to check your owner’s manual for the exact interval for your specific model.

What Affects Your Oil Change Schedule?

Your driving conditions can greatly affect how often you need an oil change. If you use your Subaru for:

• Off-roading or gravel roads: More dirt and debris can cause oil contamination faster.
• Frequent short trips: If you don’t drive far enough for your engine to warm up fully, the oil may not circulate properly, leading to buildup.
• Towing or heavy loads: Hauling gear, trailers, or extra cargo can put extra strain on your engine and oil.
• Extreme temperatures: Hot Texas summers and cold winter mornings can impact oil performance.

If any of these apply to you, consider scheduling oil changes more frequently to keep your engine in top condition.

What Happens If You Don’t Get an Oil Change?

Skipping oil changes can lead to some serious engine issues. Watch out for these overdue oil change symptoms:

• Oil Warning Light or Check Engine Light: These dashboard warnings can signal low oil levels or poor oil quality.
• Strange Engine Noises: Knocking or ticking sounds can indicate that your engine isn’t getting enough lubrication.
• Reduced Fuel Efficiency: Old, dirty oil forces your engine to work harder, reducing your gas mileage.
• Overheating & Engine Damage: In the worst-case scenario, running with degraded oil can cause overheating and even engine failure.

The longer you wait, the higher the risk of costly repairs. Regular oil changes are one of the easiest ways to extend the life of your Subaru and keep it adventure-ready.
