Is synthetic or conventional oil better for high mileage cars?

High mileage oil If your vehicle is high-mileage and high performance, it’s suggested that you go with this type of 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.

How many miles should you go on conventional oil compared to synthetic oil?

Check your owner’s manual. Newer cars may be able to go 10,000 miles or only need an oil change once a year. Turbo engines and older cars may still require oil changes every 3,000 to 5,000 miles. Synthetic oil change intervals range 10,000-15,000 miles or once a year (whatever comes first).

What are the benefits of synthetic oil over conventional?

Better viscosity. At both low and high temperatures, synthetic oils enjoy better viscosity and stability than conventional oil or synthetic blends. Full synthetic oils are designed to flow quickly in winter temperatures and resist extreme heat, allowing your engine to run smoothly year-round.

Is synthetic oil bad for high mileage engines?
