I was using it. My local Walmart stopped selling it about 1 year ago and clearanced out what they had left. Bought several gallons, but it is used up now. Very hard to find in this area. I used it in all my outdoor power equipment.
SS1970Chrysler, the Rotella T5 10w30 I got at the Wal Mart that has a TLE and it was on sale for $13 a gal, so I bought all 4 for the Farmall H and to help a friend out.
Yeah I've been using it in our Explorer for awhile now. Runs real nice on it. Its quiet, smooth, and never has any hint of startup noise. T5 is also available in a 10-40, I've tried that before too but that's getting a little thick and you start to notice it.
