It helps to reduce fuel consumption by reducing friction and improving engine efficiency. Overall, if you're looking for a top-quality engine oil that offers unbeatable protection and performance for your modern vehicle, the Castrol Edge Titanium 5W-30 LL Car Engine Oil is the perfect choice.

It has the strength to maintain this unsurpassed level of engine protection for an extended drain cycle of up to 10,000 miles between oil changes which is the interval recommended by many vehicle manufacturers.

Castrol® EDGE® is our strongest motor oil, fully synthetic and liquid engineered with Fluid Titanium Technology to make it strong enough to handle the demands of today's engines at all times.

Is Castrol Edge a better engine oil for a car? Castrol make good quality oils at a reasonable price. But whether Castrol Edge is "better" depends on the specifications your engine manufacturer recommends. If that oil meets the specifications for your car, then by all means use it.

TRANSFORMS TO BE STRONGER UNDER PRESSURE This showed that Castrol EDGE with Fluid TITANIUM physically transforms its structure – becoming stiffer at points of extreme pressure, to keep metal apart and reducing friction. When the pressure subsides, the oil reverts to its free-flowing state.

Kendall Liquid Titanium forms an extra layer of protection around critical engine parts to dramatically reduce friction and improve fuel economy.

Castrol® EDGE® Extended Performance is Castrol's most advanced full synthetic motor oil. It provides ultimate performance and the strength to enable an extended drain of 20,000 miles or a full year*.

Engines with newer technology often use synthetic oil and can travel 5,000, 7,500, and even 10,000 miles between oil changes.

The smaller the number, the better it will flow. So a 5W-30 will flow easier than a 10W-30 at start-up temperatures and a 10W-30 will flow easier than a 10W-40 at normal engine operating temperatures. This is important, as engine oils naturally thicken as they cool and thin as they are heated.
