Great Farm oil

I have been using 15w-40 Shell Rotella in my two Chevrolet farm trucks, a 2018 5.3L and a 2020 6.6L as soon as the factory warranty expires. Both trucks start fine in -15 degree Wisconsin winters. The real value is in 90+ degree summers when hauling hay from the field and hauling a skid steer for loading and unloading the 1,000 lb bales. This oil is far superior to the 0w-20 OEM OIL. I change oil and filters every 3,000-5,000 miles. BTW, I also use it in my older farm tractors. Excellent Product

The upgrade from 15w-40 T3 to T4 is night and day

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 .

Muscle Car Oil

I and many others I know use this oil because it has the high zinc we need for flat tappet cams. I have a 1972 Plymouth Roadrunner with a 440 and so far no problems.
