Hi everyone, thanks for taking the time to notice our latest product offering, Shell Rotella oil filters! The new line of high-quality Shell Rotella oil filters were introduced earlier this month and are designed to help reduce engine wear and promote longer engine life. The filters can be used with engines that require conventional or synthetic engine oils, such as Shell Rotella T Triple Protection, Shell Rotella T5 or Shell Rotella T6. The new line of diesel oil filters can be purchased at AutoZone locations nationwide, with further distribution anticipated for 2016. – The Shell Rotella Team
