Is it OK to use synthetic oil in high mileage cars?
Myth: Full synthetic oil is not good for high mileage cars or older vehicles. The myth is rooted in the idea that synthetic oil is “slipperier”—lower in viscosity, or not as compatible with seals and will therefore leak or leak more in places conventional oil might not. Again, completely untrue.
When should I use high mileage synthetic oil?
The first is to switch when your vehicle reaches 75,000 miles. The second is to switch if your older vehicle is beginning to show signs of engine loosening. If you notice an oil drip, that’s a sign you should start using high-mileage engine oil.
How many miles can you go on full synthetic oil?
It used to be normal to change the oil every 3,000 miles, but with modern lubricants most engines today have recommended oil change intervals of 5,000 to 7,500 miles. Moreover, if your car’s engine requires full-synthetic motor oil, it might go as far as 15,000 miles between services!
Should I use full synthetic or high mileage?
The short answer is full synthetic is always better, but cost is the main reason why I buy high mileage oil vs synthetic oil. If you have over 75,000 miles on your modern car or truck, consider switching to a high-mileage motor oil.

What’s the difference between high mileage oil and synthetic?
High mileage oil is designed for vehicles with more than 75,000 miles. As a rule of thumb, most new cars require synthetic oil. Older cars generally run well with conventional oil, unless your vehicle has more than 75,000 miles on it, in which case high-mileage oil is recommended.
What kind of oil do you use for high mileage?
All of these various additives help the oil do its job, but they can only go so far, which is why the world’s first high-mileage motor oil, MaxLife™ Synthetic Blend, augments natural oil with synthetic oil as its base, and MaxLife™ Full Synthetic goes all the way with a synthetic base oil.
How many miles do you need to change synthetic oil?
With later formulations of conventional oils, it was perfectly fine to go up to about 5,000 miles between changes. Some people maintain that the 3,000 mile rule was really just a marketing concept to sell oil. Synthetic oil is a lot more resistant to breakdown than conventional oil, which starts to lose its lubricating properties over time.
When to use synthetic oil in your car?
If your vehicle is older, you might want to consider one of the synthetics billed as “high mileage” oil. These oils do have a different combination of additives that might be a little better suited to engines with a lot of wear, tear, and miles on them.
Why is synthetic oil so much better than conventional oil?
Synthetic oil is now required for warranty coverage, in most cases. So why is synthetic so important, and why is it so much better than conventional oil? Let’s talk a little about the pluses and minuses of synthetic vs. conventional, and then we’ll get into why synthetic oil can go for such a longer interval between changes.
