Can I really go 25,000 miles between oil changes?

Castrol rates it for up to 25,000 miles or one year, whichever comes first. That assumes a healthy engine and the viscosity your car specifies. Follow your owner's manual if it calls for shorter intervals, and check the level regularly.

Is this the same as regular Castrol EDGE?

No. Extended Performance is the longer-drain version with a stronger additive package. Standard EDGE is rated for shorter intervals.

Does it work in turbocharged or direct-injection engines?

It meets API SP and ILSAC GF-7, which cover turbocharged and direct-injection gasoline engines. Check your owner's manual for the required viscosity and specification first.

Is it suitable for diesel engines?

No. This is a gasoline-engine oil and is not diesel compatible. Use a diesel-rated oil for those engines.

How many oil changes does the four-pack cover?

Each jug holds 5 quarts, enough for one change on most four-cylinder cars. The four-pack covers about four changes, more if your engine takes less than 5 quarts.

Is it good for high-mileage engines?

It has no high-mileage seal conditioners. If your engine leaks or burns oil, a high-mileage oil is the safer choice.

Buyers like: Great value for money, consistently lower prices; Smoother engine and improved fuel economy; Extra engine protection and longer engine life. Common complaints: Some reviewers still change oil every 5,000 miles rather than trusting the long drain interval.

What reviewers say

Owners rate it highly for smooth running, quiet ticking and low oil consumption, and several ran it close to the full 25,000-mile interval without trouble. The main doubt is the long drain interval itself, which some buyers ignore and change at 5,000 miles anyway.
