Carlube Triple R 0W-20 R-Tec 4 is a fully synthetic engine oil formulated to improve fuel efficiency and provide enhanced engine and catalyst protection for modern engines requiring low-viscosity engine oils. It delivers excellent performance in both engine protection and cleanliness, offering high-temperature deposit protection for pistons and turbochargers while improving sludge control. Additional benefits include enhanced fuel efficiency and ethanol fuel compatibility. This oil has been developed with distinct additives to maintain full vehicle performance, leading to a longer vehicle life. Unlike some traditional oils that contain higher levels of zinc and phosphorous which can damage catalysts, Carlube Triple R 0W-20 R-Tec 4 utilizes a combination of quality base oils and an innovative additive system to improve catalyst durability by reducing phosphorous content, thereby preventing catalyst poisoning and ensuring longer working life. This lubricant also helps convert harmful emissions into less harmful ones. Changing your engine oil should be based on your vehicle's type, mileage, driving style, and conditions. Always consult your manufacturer's manual for the best guidance on when to change your oil and the correct type to use. To check or top up your oil, ensure the car is on level ground and the engine is cool and not running. Open the bonnet, locate and gently pull the oil dipstick. Clean the dipstick, reinsert it fully, and pull it out again. The oil level should be between the high and low markers. If below the low marker, top up with the manufacturer's recommended grade and specifications, or book your vehicle for a service at your local garage.
