How often should I change the engine oil in my Toyota Land Cruiser?

I've owned my Toyota Land Cruiser for a few years now and I'm not sure how often I should be changing the engine oil. I use my vehicle for both daily commute and off-road adventures. What is the recommended frequency for changing engine oil in a Toyota Land Cruiser and what type of oil should I use?

As a fellow Toyota Land Cruiser owner and off-road enthusiast, I recommend changing your engine oil every 5,000-7,500 miles or every 6 months, whichever comes first. This will ensure adequate lubrication for your engine and prevent potential issues down the road. As for the type of oil, always use a high-quality synthetic oil with a viscosity grade of 5W-30.

It is generally recommended to follow the manufacturer's guidelines for oil change frequency, but with the Toyota Land Cruiser being a reliable and tough vehicle, you can stretch it to 10,000 miles before an oil change. However, I still suggest changing it every 7,500 miles to be on the safe side. As for oil type, stick with a synthetic oil and avoid conventional oil as it may not provide sufficient protection for your engine.

I've been using my Toyota Land Cruiser for over 20 years now and I've always changed my oil every 3,000 miles. It may be more frequent than necessary, but it's a habit that has served me well. So my personal advice would be to change your oil every 3,000-5,000 miles. As for oil type, I've always used a conventional oil and I've never had any issues.
