When to use high mileage oil?

If you own a high mileage car, then your engine is probably quite worn out at this point. There could be all sorts of problems with your engine. The biggest problem is the gaps between the engine components. High-mileage oils have ingredients to take care of older engines, like conditioners, seal swells, antioxidants, detergents and wear or friction additives.

Typically they use a viscosity modifier that is durable and won’t lose viscosity very easily. These oils need to stay thicker longer to protect engine parts.

Engine oil is produced from crude oil and is used for lubricating, cleaning and cooling engines. Engine oil types include conventional, synthetic, diesel, bio-based, hybrid (blends of conventional and synthetic) and recycled oils. Engine oil varies in weight and viscosity as well as in additives that some manufacturers add to the oil during the refining process. A numerical code system developed by the Society of Automotive Engineers (SAE) sorts engine oils by viscosity – the higher the number between 0 and 60, the more viscous (thicker) the oil is. Most consumer engine oils are rated with two numbers, with the first number indicating cold weather performance (winter or “W”).

This oil has a weight of SAE 5W-40, i.e. it has a SAE viscosity of 5 at low temperatures and a viscosity of 40 at normal operating temperature. Always read your vehicle’s owner’s manual to ensure that this is the correct weight of engine oil for your vehicle.

This oil is a full synthetic oil, i.e. crude oil is not used in its manufacture. Synthetic oil can be used in vehicle engines instead of engine oils refined from crude oil and often offers better mechanical performance than conventional engine oil, including higher gas mileage and less engine wear at extreme temperatures. Due to its complex production process, it can often cost more than conventional engine oil.

Pros:

• Excellent thermal and oxidation stability reduces oil aging and provides extended drain interval protection.
• Increased film strength at high temperatures. Reduce engine abrasion and polish holes.
• Inherent Stay-in-Grade shear stability for wear protection and reduced oil consumption and maintenance of viscosity in heavy high temperature applications.
• Advanced formulation and viscometry to improve fuel economy

Cons:

• Oil jugs could have crushed filters

As vehicles age, they change, and some of these changes can result in costly repairs or replacements. Catalytic converter failure is one of the most common – and expensive – problems with higher mileage vehicles. The phosphorus in all engine oil wear protection packages is also an industry recognized catalyst poison. Castrol GTX High Mileage is specifically formulated with less phosphorus than other leading oils and is replaced by an advanced technology invented and patented by Castrol that helps prevent catalyst and emission system failure and provides unsurpassed protection against sludge, wear and oil burn-up compared to leading conventional oils, 5W-30 tested.

Castrol GTX High Mileage Engine Oil is a synthetic blend oil that helps extend the life of your engine by protecting it from mud, wear and tear and burn-off, and is also liquid designed to protect your exhaust system.

One of the most common causes of engine indicator lights turning on in high mileage vehicles is catalyst failure caused by phosphorus in the engine oil.

Pros:

• Helps prevent the failure of catalytic converters and emission systems.
• Excellent dispersion against sludge formation
• Exceptional oil burn protection that exceeds industry standards.
• Seal conditioner to reduce leakage
• Advanced additives to minimize engine wear
• Improved fuel consumption

Cons:

• You may have problems with packaging of the oil
