Best Full Synthetic Diesel Oil

Bardahl 1511-CS Engine Power Booster Additive - Reduces Friction and Improves Gas and Diesel Engine Performance - 12 fl. oz. (Pack of 12)

Extra protection for engines using low sulfur diesel fuels.
Reduces friction and wear to improve gas and diesel engine power and performance.
Inhibits oxidation to reduce formation of sludge, gum and varnish deposits.
Synthetic oil stabilizer increases oil viscosity to decrease oil consumption and lower emissions.

Full synthetic 5W-40 diesel engine oil with Triple Protection Plus technology protects against wear, deposits, oil breakdown, and improves low-temperature flow.
Exceptional wear protection for longer life in a wide range of heavy-duty engine applications — from pickup trucks to tractors to semi rigs.
Enhanced fuel economy capability of 1.5 percent without compromising engine protection or durability (compared to 15W-40 oils).
Multi-functional dispersant additives provide an enhanced level of protection against the effects of soot, dirt, and other contaminants (compared to previous formulation).
Increased shear stability for better viscosity control and optimal engine oil pressure.

Mobil Delvac 1 ESP 5W-40 Engine Oil is a fully synthetic supreme performance heavy duty diesel engine oil..
Extends engine life while providing long drain capability and potential fuel economy for modern diesel engines operating in severe applications..
Utilizes state-of-the-art technology to deliver exceptional performance in modern low emission engines..
Recommended for use in a wide range of heavy-duty applications and operating environments found in the on-road transport and off-road mining, construction, and agricultural industries..

Synthetic blend 15W-40 diesel engine oil with Triple Protection Plus technology protects against wear, deposits, and oil breakdown.
Ideal for on-highway fleets, construction, and agricultural machinery, and diesel pickup trucks — including high-power vehicles that require resistance to heat and stress.
Improves low-temperature flow (compared to conventional 15W-40 oils).
Helps control engine deposits for reliability at extended oil drain intervals (always follow the OEM recommended oil drain interval).
Controls engine wear 37 percent better than the maximum wear requirements in API CK-4 engine wear tests.
Improved oxidation performance for increased resistance to oil breakdown under high temperatures compared to the previous formulation.
Case of three 1-gallon bottles with ergonomic design for easy handling and pouring.

Works with all brands of synthetic and petroleum-based oils. Including full synthetic, semi- synthetic, conventional, and mineral. Gas or Diesel engines..
Recommended to be used in all automobile, truck, lawn, marine, agriculture and heavy-duty equipment..
Increases horsepower, lowers operating temperatures and reduces engine noise and vibration in all engines..
USAGE: Use 2 ounces per quart of oil in crankcases, 3 ounces for heavy duty and towing applications. Transmissions (Automatic or Manual) Use 1 ounce per quart of transmission fluid. Differentials use 1 ounce per quart of differential fluid. Power steering systems use 1 ounce per quart of fluid. Hydraulic fluid 1 ounce per 2.5 gallons of hydraulic fluid. Motorcycles 1 ounce per quart of fluid max. Lasts multiple fluid changes but maybe used more frequently for best results..
