Oil circulates through your diesel engine at a rate of up to 100 times a minute; all the while it is being subjected to intense heat of over 400° F, and is assaulted by acid, dirt and soot. In these harsh conditions, only the toughest engine oils can survive. While most diesel engine oils break down under the pressure, test results show that Castrol® Tection™ Extra provides superior protection over the entire oil change interval, not just the first few thousand miles.
The extreme stresses present in the engine gradually break down the oil, weakening its structure and causing it to lose its viscosity. This means that with every passing mile the oil is less effective at protecting your engine. Once viscosity is lost, oil thinning, reduced film strength, and increased oil consumption are likely to occur. These factors lead to reduced performance, more wear, and shorten the life of your engine. Castrol Tection Extra’s advanced formula utilizes Castrol’s unique Active Molecule Technology to deliver second-to-none protection against permanent viscosity loss. No leading engine oil protects against viscosity loss better than Castrol Tection Extra.
As your engine runs, its internal metal surfaces are being forced together. The only thing stopping these surfaces from causing irreversible damage to each other is your oil. That’s because oil forms a film that acts as a buffer between the moving parts in your engine. The stronger the film, the bigger the buffer, the more your engine components are protected. Castrol Tection Extra maintains the size of its film under harsh conditions better than any other leading engine oil. Tests have shown that Castrol Tection Extra allows the least amount of wear from the time when you first pour it into your engine until you drain it out. In fact, Castrol Tection Extra that has already been subjected to the stresses and strains of the harsh engine environment still protects better than the leading diesel engine oil does when it is fresh.
Castrol Tection Extra exceeds the specifications of API CJ-4 and SM, as well as all previous API service categories. It is approved for use in all major diesel engines, including Caterpillar (ECF-3, ECF-2, ECF-1a), Cummins (CES 20081), Detroit Diesel (Power Guard 93K218), Navistar International, Mack (EO-O Premium Plus), and Volvo (VDS-4).
The benefits of Castrol Tection Extra include:
- Unique reforming molecules that help actively resist oil breakdown to deliver unsurpassed protection against permanent viscosity loss
- Long lasting protection from metal-to-metal contact, protecting your engine from wear and extending engine life
- Highest level of detergent content to neutralize acids generated by EGR engines
- Leading anti-oxidation performance to fight sludge build up and preserve engine efficiency
- Low Sulfated Ash, Phosphorus, and Sulfur (SAPS) technology to protect exhaust after-treatment devices in new 2007 engines
