Great value.

EXCELLENT PRODUCT

My 1994 F350 7.3L with 270k seemed to idle a little rougher running T3 but when I took the leap on running T4 I couldn't be happier. My diesel runs like a brand new truck and no more leaking! My truck has been brought to a new level with Shell Rotella T4 15w-40 ! Very excited to see how she runs the next 3 to 4k miles ! Definitely an eye opening experience in my journey with this truck .

I was concerned when I heard shell discontinued production of Triple Protection Rotella. This is my second oil change with this oil and I run it for 5000-7000 miles. UOA show great additive packs and the wear metals in my samples have decreased since the change to T4. Great oil and a great company. I've been using Rotella since the Rotella-T days.

I have been using Rotella T ever since I bought my Dodge RAM diesel in 2006. The truck is used on the ranch and often on rugged terrain. For years commuted from Houston every weekend so lots of highway driving. Exceptional oil for my Cummins diesel.

I use it in all my small engines sae30 and t4 in my powersports. Never lets me down

ROTELLA is everywhere. I see it, I use it, it doesn't let me down.

Quick and easy site to store delivery, great product.

I've used RotellaT4 in my 2002Chevy 2500HD Duramax from the first oil change and every 5000 ml. sense.

Even in gasoline engines, this stuff is great! The zinc conditions the aluminum head and the cleaning agents are great in high mileage engines too!
