I have used a few different 5w-40 fully synthetics in TS cars, and they do seem to run smoother than on a 10w-40 semi.
Any other decent 5w-40 fully synthetic should do the trick. Gulf, Havoline, Shell, and Carlube are ones I have used.
Out of the 8 TS cars I have owned, all of them have burned some oil, but I have never had a really thirsty one. They tended to use anywhere between 1 litre per 1500 miles to 1 litre every 3000 miles.
