Shell Rotella recalling antifreeze lacking 'bitterant'

| 3/25/2016

A lack of “bitterant” in some batches of Shell Rotella antifreeze and coolant has prompted the company to recall the unused product. The additive makes antifreeze unpalatable to prevent human and animal consumption.

Shell Oil Products U.S. is requesting return of all batches of one gallon bottles and 55-gallon drums of Shell Rotella Ultra ELC 50/50 pre-diluted antifreeze/engine coolant. The company is also recalling one batch (B2811293U063/30Sept15) of 55-gallon drums of Shell Rotella Ultra ELC antifreeze/coolant concentrate currently in the marketplace because these products were undertreated with bitterant, an additive used to render the product unpalatable.

Shell Rotella Ultra ELC 50/50 Pre-diluted and Shell Rotella Ultra ELC concentrate antifreeze/engine coolants are formulated to be extended-life antifreeze/coolants in the heavy-duty engines found in on- and off-highway vehicles, and in marine, farm, mining and construction equipment.

If any of these products are already installed in a cooling system, they do not need to be drained or replaced; it is important to note that the lack of bitterant has no impact on product performance. The Shell Rotella Ultra ELC 50/50 pre-diluted antifreeze/coolant does have warnings on the label and child-resistant closures.

We request that distributors, customers and retailers remove these specific products from their inventory, segregate them from saleable products and return or recycle it. Consumers who have product in their possession should visit to begin a claim process. Open product should then be taken to their local recycling facility or auto parts store to be recycled. Additional instructions around recycling can be found at

As part of the product return process, we have created a return policy for a return of product. Full details are available at the Rotella product return site.
