Steve;
they may have changed the formula, but so far it works for me...... I don't think I have ever gotten rid of a vehicle with less than 100,000 miles on it and have not had any problems with any vehicles I've had, so far, knock on wood.......
As long as I get the mileage out of my vehicles like I have been getting without any engine problems, I'll stick with Rowtella T........
I also use it for the break-in/dyno of my race motor, then afterwards switch to 20/50 Mobil 1
synthetic.......The Mobil 1 holds up a lot better to the high
oil temp I see in the race motor........
