Features and Benefits

Many modern, low emission diesel engines generate more soot and operate at higher temperatures than older engines. This significantly increases the need for supreme performance lubricants. Current tighter engine designs reduce oil consumption, resulting in less fresh oil makeup to replenish depleted additives. Top piston rings are located higher, bringing the oil film closer to the combustion chamber and exposing the lubricant to severe thermal stresses. Mobil 1 Turbo Diesel Truck 5W-40 helps to maintain outstanding performance at significantly higher temperatures than other high performance diesel engine oils. It is also fully compatible with conventional oils. The key potential benefits include:

Features	Advantages and Potential Benefits
Meets or exceeds demanding specifications of a major OEM	One engine oil for mixed fleet operations
Outstanding thermal and oxidation stability	Helps to reduce low temperature sludge build-up and high temperature deposits
Enhanced film strength at high temperatures	Helps to reduce engine scuffing and bore polishing
Inherent stay-in-grade shear stability	Wear protection and reduced oil consumption; helps to maintain viscosity in severe, high temperature service
Advanced formulation and viscometrics	Aids fuel economy
Low volatility	Helps to control oil consumption
Exceptional low temperature pumpability	Easy engine start-up and helps to reduce wear
Enhanced TBN quality reserve	Helps to deposit control and extended drain capability
Outstanding resistance to corrosion	Helps to extend life of critical wear surfaces
Long drain capability	Helps to increase operating efficiency and lower overall cost
Component compatibility	Long gasket and seal life, helps to extend service intervals

FAQs

What’s the difference between new Mobil 1™ Truck & SUV motor oil and Mobil 1™ Turbo Diesel Truck motor oil?

One is for gasoline‐powered engines and the other is for diesel‐powered engines. Mobil 1 Turbo Diesel Truck motor oil is designed for light‐duty diesel trucks that require an oil that meets or exceeds the latest industry and diesel engine builder requirements. Mobil 1 Truck & SUV motor oil is designed for gasoline‐powered, light‐duty trucks and SUVs. This newly formulated product provides outstanding performance and protection in normal and more severe driving conditions, such as towing and hauling. Performance has been proven in a 120,000‐mile test, which included over 50,000 miles of simulated towing of a 5,000‐pound load.

How often should I change the oil if I'm using Mobil 1™?

Mobil 1 Supercar 0W-40 motor oil is the result of almost 24 months of grueling tests and precise engineering. While the viscosity is identical, the formulation of Mobil 1 Supercar 0W-40 motor oil is specifically designed to guarantee it meets the strict dexos^®-spec required for all seventh-generation and later Corvette models and it is not interchangeable with Mobil 1 0W-40.

Will the use of Mobil 1™ void my new car warranty?

With the exception of the Mazda rotary engine (Mazda does not recommend any synthetic oils), Mobil 1 will not void new‐car warranties where an American Petroleum Institute (API) certified oil is recommended. Mobil 1 meets or exceeds API and International Lubricant Standardization and Approval Committee (ILSAC) motor oil service requirements of all new‐car manufacturers, both import and domestic. If in doubt, always check your vehicle owner's manual or contact the vehicle manufacturer.

Rated 5 out of 5 by DonL from I'm a believer I switched my 2005 TDI Jetta wagon to Mobil 1 TDT at 100,000 miles. That was 253,000 miles ago. At 353,000 the engine still runs pretty much perfectly. I do 5,000 mile oil changes religiously. MPG ranges from 48 to 53.

Rated 5 out of 5 by Cpl Ski from Keeps the generators going I started using Mobil 1 5W-40Turbo Diesel, in my portable gasoline generators, for ease of starting in winter, and for ability to handle the heat of air cooled engines in summer. Fuel usage is down, so is internal engine noise. If you find a better oil, buy it.

Rated 5 out of 5 by 5.9 Cummins from 220000 miles and still going We stuck a bore scope down and everything looks brand new still. I will admit I change every 6000 miles when I know we can go longer but for an 07 5.9 common rail the 15 year old engine looks great for hauling a 14k lb 5th wheel for most of its life and miles.

Rated 5 out of 5 by Sizmo from Best Wear Numbers from oil analysis I’ve ever seen I have a 2014 VW Passat TDI and sent the oil in for analysis to see how it was wearing. I couldn’t believe all the low wear numbers. Way below the averages for my engine and mileage. My car’s DPF, EGR, and SCR system fell off which is why I’m not using the VW 507 approved oil by the way. If you have a TDI with the emissions still intact, I would recommend using this oil instead of the “approved” VW 507 oils. The oil thickness once warm (100* celcuis spec) is not much higher than the 507 approved oils. Think of it as the TDT is a “thinner” 40 weight, and the VW 507 oils a “thicker” 30 weight oil. The ash # is still low enough to use in anything with a DPF. I have switched over to the Mobil TDT in all 6 of my Diesels I own. The anti-wear additive is very robust.
