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 1 out of 5 by Hendu from Different color oil between gallon and quart sizes Purchased 2 gallons and 2 quarts on 6/27/2020. Both quarts were a much darker color than the gallons. If I wasn't forced to use these two quarts, I would not have. Might need to switch to Rotella....

Rated 1 out of 5 by J513 from Different products in same jug Today (3/7/20) I purchased 2 gallons of 5W-40 Mobil 1 TDT. During my oil change I noticed whil pouring the second gallon, the oil color was different from the first gallon. It appears to be 2 diferent products in the same labeling, nothing denoted "new formula" or any other changes, just a slightly different label design on the back.

Rated 5 out of 5 by Jack75 from Great product Have a 2015 Ford Superduty 6.7. Been using this product for 244,000 miles with no issues. Changing the oil at 7500 mile intervals. Only down fall is the cost, but you get what you pay for.

Rated 5 out of 5 by Jeffes4500 from Works for me 2002 7.3 Even though it isn't recommended for a 7.3 Diesel I've been using it 4 years now. My truck loves the stuff. It starts much easier on cold mornings not even plugged in you can tell a big difference from the standard 15-40 Diesel oil. I pull a 10,000 lb trailer from Ogden Utah to Aguilar Colorado once or twice a year. I haven't had any oil related issues at all. Starts and runs quieter with great oil pressure and no oil leaks period. I change the oil once a year now 5000 -7000 miles is normal. The truck has 168000 miles on it so it isn't a high mileage truck but it gets used for pulling. It might not be recommended for the 7.3 but my truck runs better with it. Doesn't matter the weather conditions either...cold or hot this oil makes my truck run better. I don't know much about oils I just wanted to try it cause I had slow cranking issues in cold weather here. Won't go back to 15-40 stuff unless I can't get the 5-40.

Rated 2 out of 5 by Chuckwagon from Not recommended for older powerstroke diesels Mobile one's online product finder does not recommend this for 7.3 Powerstroke Turbo Diesel trucks. Too bad. I use M1 in my cars and like it. Probably it's lower viscosity won't work properly with injection system.

Rated 5 out of 5 by Ron25 from Best oil on the market I have a 2005 Silverado 2500 with LLY duramax diesel. I have used mobile 1 turbo diesel since new. I now have 351000 miles without ANY problems, truck still runs like new, I have original injectors and turbo, I change oil using vehicle oil monitor, usally at 10000 miles between changes . I also use mobile 1 synthetic trans fluid and mobile 1 75w 90 synthetic gear oil. Never had a rebuild on trans or differential. I wouldn't use anything else.

Rated 5 out of 5 by MacAttackKamaaina from Perfect for nissan v6 VG33E Used this in my gasoline engine. After purchasing my used 2001 Nissan Xterra V6 I noticed a little engine noise. I messed with a few different oils and noticed how picky this engine is with different viscosities. To make a long story short, finally I tried the 5w-40 tdt and I couldn't be happier. The engine runs like new, smooth as butter, has plenty of power and is quieter than ever. For smooth, quiet operation with maximum protection I would use this oil in anything requiring 5w-30 , 10w-30 or 10w-40

Rated 1 out of 5 by Jesse from Contaminated fresh oil Upon opening a new 3.78 liter jug I noticed a purplish tint and after filling the engine there is fine dark residue left inside the jug. Going back to AutoZone foot reimbursement of said oil and now a new filter. Hopefully this didn't ruin my engine before I make it to AutoZone and back home.

Rated 5 out of 5 by JimB from Run your engine FOREVER! I own a 99 VW Golf . Ive repaired or replaced near every major part on this car but the engine which has never been touched. Only Mobil Delvac1 or Turbo Diesel 5w-40 used every 6-7000 miles since it came off warranty. Still get 50+ highway MPG and the only oil it burns is the diesel its supposed to. The car now has 432,000 mile on it! I attribute that to your oil as I know other TDI owners who use other brands that haven't made half that distance before rebuild or junk yard. Great stuff.

Rated 5 out of 5 by Brett97 from worry free performance When i bought my 1997 f250 from the original owner i didnt immediately switched to mobil 1 oil. I use my truck for some daily use, towing, and traveling and noticed some cold weather performance issues. I switched over and the hard starts went away, it ran smoother with less warm up time, and I've noticed small MPG gains. I've even stretched a couple oil changes out to almost a year and 8k miles and I could still see through the oil when i drained it. Money well spent!

Rated 5 out of 5 by LongtimeBenzOwner from Beneficial in 1985 Mercedes 300D Turbo Diesel Quiets valve train noise better than any other brand I have tried. This product keeps cam follower noise completely subdued all the way to the next oil change. With all the other brands I have tried some valve train noise begins to be heard a few thousand miles after oil change and by the time the oil change mileage is reached the valve train noise is quite conspicuous. This would suggest that this oil can maintain excellent shear strength throughout its useful life. No small comfort here when I consider all the other crazy expensive parts this stuff may be keeping out of metal to metal contact .

Rated 5 out of 5 by Swathstrider from Why would you use anything else? I have been using it in a 2009 GMC with a DuraMax. I tow a winterized 5th wheel rec trailer which is heavy and a 5th wheel 16 foot dump trailer when not on holidays. I have driven the Highway through **** and the grapevine at 30 deg C at posted speeds which caused the cooling fans to come on and the temp to rise. I now have 169,000 km and change oil at factory recommended times. The engine has not missed a beat and started easily in -30 deg C with out being plugged in. I have been impressed with how well the oil flows at some of our cold temp and how well the oil sticks at the high temps.

Rated 5 out of 5 by atolabor from Fantastic oil for light duty trucks My 2000 Dodge 2500 tower a 40.5 foot fifth wheel so I wanted the best motor oil I could find for my truck. I now have over 220000 miles on it and purrs like a kitten. I change it every 7000 miles along with either the Mobile oil filter or the K&N filter. If your looking for a full sythitic oil for your light duty truck this is it. Thanx Mobil1. I'll see you at 500,000 miles I'm sure of it.
