Shell Rotella heavy-duty engine oil is now backed by a lubrication limited warranty. It comes free with the purchase of Rotella T6 full synthetic, Rotella T5 synthetic blend, or Shell Rotella Triple Protection heavy-duty engine oils. The warranty covers 10 heavy-duty diesel engine parts for do-it-yourself and installed customer oil changes for up to 10 years or 800,000 km.

The warranty covers class 2c to class 8 vehicles with diesel engines used in on-road applications with a gross vehicle weight of 80,000 lb/36,000 kg or less. The vehicle to be covered may be owned or leased, but must have been driven 80,000 km or less when the owner first used an eligible Shell Rotella engine oil. The manufactured date of the vehicle must also be within the last 24 months of the first use of an eligible Shell Rotella engine oil. Other conditions apply.

The warranty is good for up to 10 years or 800,000 km (whichever is first) with exclusive use of Shell Rotella T6 full synthetic engine oil. It covers up to 10 years or 400,000 km (whichever is first) with exclusive use of Rotella T Triple Protection 15W-40 or Rotella T5 synthetic blend 10W-30 and 10W-40 engine oils.

The warranty takes effect six months after the first purchase of eligible Shell Rotella engine oil and remains in effect as long as the terms and conditions of the program are followed. Complete terms and conditions and easy enrollment are available here.
