Is Shell Rotella T6 Full Synthetic really that good...:?

T6

Should I make this my new oil?

 

I have been using the 5-40 rotella t,no problems. If you have a john deere tractor supply company,you can get the john deere "50"plus oil. It is still CI-4 rated and costs $14.50 a gallon. I just got some yesterday,and am gonna run it. They are gonna keep the CI-4 rating for a long time. Hope this helps. The john deere plus 50 is 15-40 oil..

 

ok, now I am between:

Delvac 1 vs. Rotella synth vs. Premium Blue Extreme

Any recommendations?

I like the Rotella syn 5-40 i have used it since 500 miles. i can find it anywhere when i'm on the road if i need it. i dont buy in to all the this oil is good and this oil is bad. if it's for a diesel. I wont worry about it.

 

I normally use Rotella T. Always have until the Delvac sale. I grabbed enough oil to do two changes. After that it will be which ever non synthetic is cheaper of the two.
