Rotella T6 Is Now Available

Shell’s Rotella T6 5W-40 synthetic heavy-duty motor oil is great at protecting engines (both diesel and gas). It’s equivalent to Mobil’s Delva 1 ESP 5W-40 so there is a lot of demand for it. However, many people have had trouble getting Rotella T6 over the past year or so. Some manufacturers have experienced production shortages (more on that below). The good news, you can buy Rotella T6 here right now.

Why Is Rotella T6 the Preferred Synthetic Oil?

Here are some of the benefits Rotella T6 offers:

Engine Wear Protection

It provides excellent protection and durability for your engine compared to similarly specced engine lubricants. Shell designed Rotella T6 to provide improved engine wear protection and lengthen the service life of engine parts.

Improved Fuel Efficiency

Every little bit counts with fuel savings and Rotella T6 5W-40 was engineered by Shell to improve mileage by 1.5% when compared to 15W-40 oils.

Temperature Efficiency 

Rotella T6 synthetic oil is one of the best motor oils for extremely hot or cold temperatures, as its design facilitates reliable functionality in the harshest of environments. It can withstand temperatures as low as -30° F without sacrificing energy efficiency so you can expect smooth startups even on the coldest days.

Reduced Engine Deposits

Tiny particles of dirt and metal slivers can harm your engine significantly if they mix in the oil and find their way to the engine. The damage rarely results in an instant and catastrophic breakdown, but it will shorten the vehicle’s overall life.

By combining advanced multi-functional dispersant additives with synthetic base oils, Rotella T6 offers an elevated level of protection against the detrimental buildup of dirt, soot, and other pollutants in heavy-duty diesel engines.

Emissions System Compatibility

Rotella T6 has an advanced low-ash composition that prevents clogging and contamination of exhaust after-treatment equipment, a key factor in optimizing engine fuel efficiency and keeping vehicles in compliance with pollution standards.

Which Product Is Rotella T6 a Good Substitute For?

Rotella T6 is not only a good substitute for Mobil Delvac 1, it can also be used in place of Chevron Delo 400 or Amsoil Heavy-Duty Synthetic Diesel Oil. Additionally, you can use Rotella T6 as an alternative to conventional mineral oils.

However, you shouldn’t just fill up your vehicle without ensuring the manufacturer approves of Rotella T6. Always verify that the motor oil falls within the manufacturer’s recommended engine lubricant specifications before changing the engine oil.

The Shortage of Rotella T6

The exact cause of the recent Rotella T6 shortage remains unknown (however, Keller-Heartt has been able to maintain availability for customers throughout the shortage). Here are some theories on what was behind the shortage for other suppliers. 

  • A fire at a storage facility that spread to a nearby refinery.
  • One of the manufactures who created an additive for Rotella T6 ceased production due to COVID.
  • The nationwide backlog of containers at land ports slowed the delivery of the product. 

Whatever the case, Shell is back to producing ample quantities of Rotella T6 now.
