Product Description
PRODUCT DESCRIPTION
Taro® 40 XL is a high performance, very high alkalinity diesel engine oil for medium speed trunk piston diesel
engines burning residual fuels with a maximum sulfur level of 4.5%.
CUSTOMER BENEFITS
Taro 40 XL delivers value through:
• Wear protection — High BN levels control cylinder liner wear effectively and protects bearings from
corrosion. High performance antiwear additives provide excellent protection against adhesive wear
for cams, camshaft and bearings.
• Excellent foaming and water tolerance — Helps provide a high degree of water tolerance and
antifoam protection.
• Detergent/Dispersant Properties — Keeps crankcases and oil control rings clean. Prevents
deposit formation throughout the engine. Reduces lube oil filter blockage. Effectively handles
insolubles.
• Oxidation stability — Oxidation inhibitors protect the oil against high thermal stresses, protect engine
parts from corrosion and reduce undercrown deposits, while promoting extended lubricant life.
• Rust protection — Prevents corrosion of engine parts when the engine is not in operation.
• Balanced additive components — Provides minimal maintenance and down-time, long engine
life and economical operating costs.
FEATURES
Taro 40 XL is blended from high quality base oils and additives that provide an extra margin of protection
against ring sticking, piston deposits, and wear under severe operating conditions.
Taro 40 XL has very good viscosity control when used in severe high temperature service and its excellent
alkalinity retention characteristics help prevent corrosive wear over long periods of operation.
The unique detergent and dispersant additive system promotes outstanding piston cleanliness as well as
superb heavy fuel related contaminants handling characteristics. This helps reduce both “hot” (piston
lands and grooves, piston undercrown, purifier preheaters) and “cold” (crankcase, cambox, rocker
area, fuel pumps, purifier bowl) deposits.
Taro 40 XL has good water separation and base retention properties.
APPLICATIONS
Taro 40 XL is recommended for trunk piston diesel engines burning residual fuels with a maximum sulfur
level of 4.5%.
Taro 40 XL SAE 40(X) meets the requirements of most
major marine diesel engine manufacturers.
