Unlike regular car oil, synthetic oil is more refined which can lower friction, reduce engine sludge, and increase engine performance. It’s recommended that you change synthetic oil every 7,500 – 15,000 miles, depending on the vehicle and the brand of synthetic oil used.
Should I change synthetic oil based on miles or months?
The number of miles a car sees begs the question, should I change synthetic oil based on months or miles?

How often should you change your engine oil?
There is a permanent thickening of the oil. Some automotive manufacturers are backing down on oil change intervals to 5,000 miles or less and some advocate changing the oil at least every 6 months as well. I think this is because of the tendency for oils to thicken in very hot engines (not ambient conditions, just hot engines).
How many miles between oil changes is normal?
Most manufacturers and mechanics that use synthetic oils are saying that 7500 miles between an oil change interval is completely normal for just about every vehicle in which they are used.

What happens if you don’t change your oil?
Of course, if you don’t change your oil on time and with the proper products, it could void your car’s warranty. However, car experts now say that the standard oil change interval of every three months — or every 3,000 miles (4,828 kilometers) — is old news, and that most cars can travel quite a bit farther before needing the oil replaced.
The longer an oil change is put off, the engine in general will start to show problems. Most commonly, your engine will simply become too hot, which can cause it to run less efficiently. If the heat doesn’t cause a gasket to blow, it will warp the parts of your engine.

The air cleaner is always suspect but that depends on where you drive. I believe it’s the oil that’s causing the change, the smoothness makes you rev the car more and it will feel more responsive.

What happens if you don’t change car oil for a year?
When oil has not been changed for a long time, it will begin to gel or solidify in an engine, eventually turning into sludge. When this happens, the oil will not be able to reach all parts of the engine, leading to oil starvation in the crankshafts, bearings, camshafts, and other valve train components.
What happens if you don’t change your engine oil?
One of the biggest dangers of not changing your oil is sludge buildup. Sludge occurs when old oil begins to gel or solidify in an engine. When sludge begins to build up, oil isn’t able to flow freely through the engine and can cause oil starvation to crankshafts, bearings, camshafts, and other valve train components not be lubricated.
Can you put too much oil in a car?
Yes, you can definitely put too much oil in a car. Each engine is different and will have a different oil capacity. The larger the displacement of the engine, the more oil it will take to keep it properly lubricated.
