How do I properly maintain my Toyota Land Cruiser's engine?

I recently purchased a Toyota Land Cruiser and I want to make sure I am taking the best care of its engine. What are some recommended maintenance steps I should regularly follow to ensure my engine's longevity?

First and foremost, make sure to keep up with regular oil changes according to the manufacturer's recommendation. This will help keep your engine running smoothly and prevent any potential damage.

In addition to oil changes, it's important to regularly check and replace your air filter. This ensures that your engine is receiving clean air and helps with fuel efficiency.

Don't overlook the importance of regular tune-ups and inspections from a certified mechanic. They can catch any potential issues early on and help prevent more costly repairs down the line.

Investing in high quality fuel and regularly using fuel additives can also help keep your engine running smoothly and protect against wear and tear.
