Why is it important to regularly change your Ford Focus's oil?

I've had my Ford Focus for a few years now and I've never changed the oil. Is it really necessary and if so, how often should I do it?

Yes, it is very important to regularly change your Ford Focus's oil as it helps to maintain the engine's performance and prolong its lifespan. Generally, you should change the oil every 5,000 to 7,500 miles, but it's best to consult your owner's manual for specific recommendations.

Regular oil changes also help to prevent any build-up of sludge or debris in the engine, which can cause damage over time. It's a small investment that can save you from costly engine repairs in the future.

I recommend using high-quality synthetic oil for your Ford Focus as it offers better protection and lasts longer than conventional oil. It may cost a little more, but it's worth it in the long run.
