Warning - Shell Rotella no longer has gasolene engine designation
After buying oil for my 25 hour oil change on my '17, I noticed that the graphics on the 1 Gallon bottles of Rotella conventional 15W40 had changed. I did a detailed read of the label and found that they have replaced Rotella T with Rotella T4 as their conventional (dino) oil. The T4 does NOT have the S designation that is required for gasolene engines. (as in SN). Since I always run conventional oil until the 75 hour oil change, it looks like I can no longer use Rotella (unless I can find some of the older Rotella T) I know Rotella has been a popular oil for use in our boats due to the 15W40 requirement and thought some of you may be interested in this,
Not sure how to deal with a long link?
