Frequently Asked Questions

What are the advantages of using synthetic oil over regular engine oil?

There are a whole host of advantages when using synthetic oil. This type of oil tends to last a lot longer than regular oil so most car owners will get far more use out of it.

Although it is more expensive, it allows you to change the oil every 5,000 to 7,000 miles as opposed to 2,000. Over time, this will save a considerable amount of money and, of course, effort.

Furthermore, unlike regular oil, synthetic oil doesn’t contain any impurities meaning it is better for the environment and ecosystem. It also leaves a lot less sludge on your engine so your motor can run smoother without parts getting clogged up.

Synthetic oil is more advantageous in hotter and colder weather conditions too. It keeps levels of oxidation very stable so your vehicle can start quickly and become more efficient on colder days as well as in hot temperatures.

Is synthetic oil better for high mileage cars?

The overall consensus on this is that synthetic oil is better for high mileage cars because of its special formula that extends the life of high mileage engines. It is rare to see brands advertise high mileage oils for cars with over 75,000 miles on the clock.

Although it isn’t vital to change to synthetic oil at this point, you should consider changing it the closer you get to 100,000 miles as synthetic products will add an extra layer of protection to your engine and its parts.

Like most things, the older your vehicle gets, the more care and attention it will require.

How often should I change synthetic oil?

This can vary with each vehicle. Most of the time, the timing can depend on the way you drive your vehicle and how much stress has been put on the engine.

Nonetheless, it is highly recommended you change synthetic oil every 3,000 to 5,000 miles to ensure it continues to protect all assets of your engine.

If you’re unsure about your particular engine, you should consult your car’s user manual. Different manufacturers make recommendations on how often you should change it so the overall recommended mileage could differ with some car models.

Every engine has different circumstances such as its age, how often it is used, and how it is driven. If you’re in any doubt, it is best to change it every 3,000 to 5,000 miles just to have peace of mind and err on the side of caution. 

Synthetic engine oil will ensure your vehicle runs for a longer period of time with higher fuel efficiency so it is recommended you change to synthetic oil to save money and improve your vehicle’s performance.
