5.00 out of 5 stars reviewVerified Purchaser09/28/2022Hiqh Quality LubricationI like this oil because I don't have any oil consumption issues. It is the recommended oil for my diesel pickup (10.5 quarts). I change it and filter myself at approximately every 8,500 to 8,800 miles (10K recommended by Ram). About .5 quart is missing when it is changed with the filter. This has been consistent since it was new. No leaks are apparent. Currently have 80K miles on the engine.Osoprimero

5.00 out of 5 stars reviewVerified Purchaser06/21/2022Marine diesel switch to T6I have a 17 year old Volvo TAMD41P-A diesel in my 31' recreational trawler. Prior engine oils for the prior owner (11 years) and me have been 15-40 dino oils, until I switched to full synthetic engine oil, also 15-40. Operating temperature dropped 5 degrees at standard cruising RPM of 1800 to 2200 (only one of two thermostats in place most of that time), the engine runs quieter and more smoothly. Based on research I have found, I know that my engine is running cleaner, with other attributes of reduced internal corrosion, less wear, etc. After installing 2 new thermostats, the engine runs precisely on specification for operating temperature through the full range of RPM, right up to wide open throttle, 3800 (end of the day 10 minute spike to clean the exhaust system ). Further, smoke when starting is greatly diminished to almost zero. I am completely satisfied that I am doing all that I can to accomplish optimal engine performance and protection with Rotella T6 over the last two years, and I am comfortable recommending Rotella T6 to boating friends with diesels, confident in the cost/benefit of using the best oil quality, grade and viscosity for my application.Sandy

5.00 out of 5 stars reviewVerified Purchaser09/18/2021An excellent oil for diesels.Have used this oil for 20 years to maintain three successive Sierra 3500 Duramaxes. I noted an improvement in mileage when I first switched over and have never experienced a single wear related engine issue even beyond 200,000 miles.glengold

1.00 out of 5 stars reviewVerified Purchaser07/12/2021One of the gallons of oil had been damaged and leaked oil soaking the shipping box. The box was then left on my front porch. There are now oil stains on the porch. The box had obviously been treated with very little care. The delivery person should have certainly known not to put a leaking box containing oil on a customers porch. At the very least the damaged gallon container of oil needs to be replaced.Connie

5.00 out of 5 stars reviewVerified Purchaser04/12/2021Recommended for 3.0 Ecodiesel Ram and JeepsThis oil is approved for the 2014-up Ram and Jeep Ecodiesel engines which used to require Penzoil Euro at $9-$10/quart. This meets mfg. requirements for low ash and proper lubrication for around half the price.Mikelikesbbq

5.00 out of 5 stars reviewVerified Purchaser12/27/2020You deserve to have the best.Been around diesel equipment for forty years and have tried other oils but have always gone back to shell Rotella. Check truckers websites, read articles about diesel oils. I would not but anything in my diesel engine except Rotella now for the best grade T6 is what you want .JIM

5.00 out of 5 stars reviewVerified Purchaser09/05/2019Best 5W-30 oil currently available!I use this oil in my car's GDI engine and I know several people who love using it in their high performance Subaru engines like that of the STi, WRX, and Forester XT. It just doesn't shear like other 5W-30 oils often do. I am very happy that Shell offers this product but it is very difficult to find in stores and usually online retailers offer it at a more premium price. I hope it is made more commonly available in the future!Ignatius

5.00 out of 5 stars reviewVerified Purchaser04/25/2019Would give it a 6-Stars if I couldThis oil is excellent ! Have used it and continue to use it in all my Subi's (Subarus) with every oil change. I have owned 3 of them ! It provides the protection required by these high performance engines and more. Keep my engines run smoothly and clean ! Excellent choice and can't beat the price !Wil_C

5.00 out of 5 stars reviewVerified Purchaser03/08/2018Works great in my motorcycle!I have been using this oil in my 1998 Honda F6 Valkyrie Tourer for 6 years now, and have had no issues with clutch operation. Even at full throttle with the big 6 cylinder engine, no clutch slippage. Also, the notorious Valkyrie top gear whine was a lot quieter immediately after the first oil change. It's also priced a lot cheaper than the competing oils, a nice added bonus. I don't hesitate to change the oil when I should, when the price is about half of other high end or OEM oils. It's available at many local retailers, so, it's easy to obtain. I wish it was available in other weights like 5W20. I would use it my 2010 F150 5.4L if I could, because it's really not that much more expensive than conventional oil.Crop Duster
