Performance

The Carlube Triple R 15w40 high mileage semi synthetic engine oil provides strong engine performance and protection. The multi-grade 15w40 viscosity provides excellent protection across a wide temperature range, from cold starts to high operating temps. It flows well when cold to reduce engine wear during start up but also maintains a protective viscosity when hot.

The semi synthetic formulation uses a blend of conventional and synthetic base oils to balance engine protection and fuel economy. It provides better protection and cleaner operation compared to conventional oils. The detergent and dispersant additives help keep critical engine parts clean to minimize deposits and sludge buildup. This allows the engine to run smoothly while maintaining fuel efficiency.

Overall, the Carlube 15w40 oil is designed to deliver reliable all-round performance in high mileage engines while helping extend engine life. The combination of synthetic base oils and advanced additives promote long engine life by reducing wear, controlling deposits, and retaining viscosity.

For those who need a fully synthetic option, consider the Carlube Triple R, R-TEC 20, 5W-30 ACEA C3-16 Fully Synthetic Engine Oil 1L. This oil offers superior protection and performance for modern engines. It meets the latest ACEA specifications and is designed to optimize fuel efficiency while minimizing emissions. Its low viscosity ensures excellent cold start performance and rapid oil circulation throughout the engine. The fully synthetic formulation provides enhanced durability and protection against wear, making it an ideal choice for those seeking maximum performance.

Oil Viscosity

Carlube Triple R 15W40 engine oil has a viscosity grade of 15w40, which refers to the oil's viscosity or thickness at different temperatures. The "15" indicates the viscosity when the oil is cold, while the "40" refers to the viscosity when the oil is hot.

A 15w40 oil like Carlube Triple R has a relatively high viscosity when cold, allowing for easier cold starts and cold weather performance. The oil flows well when the engine warms up due to the lower hot viscosity rating. This makes 15w40 oils a good choice for a wide temperature range.

The 15w40 viscosity grade is commonly recommended for gasoline engines in Europe and Britain. It provides adequate viscosity to protect high mileage and older engines from wear and oil consumption issues. 15w40 oils are also frequently used in diesel engines in Europe. Overall, Carlube Triple R 15W40 is formulated with a versatile 15w40 viscosity grade suitable for many vehicle makes and models.

In addition to the 15W40 option, Carlube also offers Carlube Triple R, R-TEC 21, 5W-30 ACEA C3-21, Low SAPS Fully Synthetic Engine Oil 5L. This fully synthetic engine oil is designed for modern engines, providing excellent protection and efficiency with its low SAPS (Sulfated Ash, Phosphorus, and Sulfur) formulation. It is suitable for a variety of high-performance vehicles, ensuring optimal engine cleanliness and longevity.

High Mileage Formulation

The Carlube Triple R 15w40 engine oil is specifically formulated for high mileage engines. As engines accumulate miles and age, they develop issues like oil leaks, reduced compression, and increased oil consumption. High mileage engine oils contain special additives that help address these problems.

Some of the key benefits of the high mileage formulation include:

• Seal conditioners - These additives revitalize worn seals and gaskets to reduce oil leaks. They help restore flexibility and expand seal size.

• Oil thickening agents - Polymers are added to increase oil film thickness and reduce oil consumption in older engines. This provides better protection.

• Anti-wear additives - Extra anti-wear additives protect against damage from friction as compression decreases. This extends engine life.

• Detergents - Detergents keep engines cleaner by preventing deposit build-up. This improves performance in high mileage engines.

The Carlube 15w40 utilizes premium high mileage additives to restore protectiveness and reduce common issues in older engines with higher miles. Drivers will benefit from optimized performance, reduced oil consumption, and protection against wear.

Pros

• Designed for high mileage engines. This oil is formulated to provide extra protection for older engines with more wear. The seal conditioners help reduce oil consumption in engines prone to leaks.

• Good thermal and oxidation stability. The synthetic blend stands up well to high engine temperatures over time. Reviewers report the oil retains its viscosity and doesn't thicken or break down prematurely.

• Decent all-weather performance. The 15W-40 viscosity provides enough flow for cold winter starts while maintaining sufficient protection in hot weather. Not the best for extreme cold climates though.

• Cleans and prevents sludge. Contains dispersants to suspend contaminants and detergents to help break down existing sludge deposits inside the engine. Helps maintain engine cleanliness.

Cons

• The oil viscosity of 15W-40 may be too thick for some newer engines that require lower viscosity oils like 5W-30. Using an oil that's too viscous can lead to increased fuel consumption.

• It's not a full synthetic oil, so it may not provide the same long-term protection against sludge and deposits as a full synthetic. The semi-synthetic formulation could require more frequent oil changes.

• While it claims to be suitable for high mileage engines, some reviewers report it did not resolve oil leaks in very high mileage vehicles over 150,000 miles. So it may not offer the best seal conditioners.

Value

The Carlube Triple R 15w40 high mileage semi synthetic engine oil offers excellent value for the price. At around £10-15 for a 1 liter bottle, it costs slightly less than many comparable engine oils from brands like Castrol, Mobil and Shell.

While not the absolute cheapest oil on the market, the Carlube oil provides very good quality for a mid-range price point. For drivers looking to balance price and performance in higher mileage vehicles, this oil hits a nice sweet spot.

The semi synthetic formulation helps provide enhanced protection and cleaning power versus conventional oils, without the premium price tag of full synthetics. For the average driver putting normal mileage on their vehicle, Carlube's Triple R offers solid value.

Overall, this oil gives you strong quality and protection per pound spent. While cheaper generic oils are available, the Carlube brand has a good reputation for reliability. For drivers who want a dependable oil that won't break the bank, the 15w40 high mileage formulation is a solid choice.

Conclusion

In conclusion, Carlube Triple R 15w40 is a quality semi-synthetic engine oil that offers good value for high mileage engines. Its 15w40 viscosity rating makes it suitable for a wide range of temperatures, while the high mileage formulation helps condition seals and reduce oil consumption in older engines.

The key pros are its ability to protect high mileage engines, reduce oil leaks, and maintain stable oil pressure. It provides good protection against wear and tear while also keeping engines clean. The price is affordable for a semi-synthetic option.

Potential cons are that it may not offer the maximum protection of a full synthetic, and some engines may benefit from a lighter viscosity oil. It also lacks any official certifications from major manufacturers.

Overall, for drivers looking to prolong the life of an older, high mileage engine, Carlube Triple R 15w40 is a solid choice with its targeted high mileage formula. The semi-synthetic blend offers a good balance of performance and value. Unless your engine specifically calls for a different viscosity grade or full synthetic oil, this Carlube oil should provide reliable performance in most older vehicles with high mileage. It's a good option for the money.
