Hi my name is Bill Stein and I have been formulating industrial lubricants for 35 years at our Shell Technology Center here in Houston.
With our Turbo S4, what we've done is we started with a GTL-based oil, which is a gas-to-liquids technology for Shell, and we've actually built a proprietary additive package into that.

We've minimized deposit formation in the actual application. So during some of our field trials we've seen some very good performance with this new product.
Recently, ASTM has developed a new dry TOST test, that we were a part of. This particular test stresses the oil in a very different way than some of the other tests have and it actually will produce deposits and varnish quicker and even probably more accurately than other conventional tests which have been around for 40, 50 years.
The newer dry TOST tests will kind of mimic what's going on in the turbine better than some of the older tests.
We see varnish forming, which would kind of equate to varnish forming in the machines, on bearings, on surfaces and also on the servo valve.
With the lower quality oils, you have all kinds of performance problems.

More Deposits
Foaming
Less Air Release
Text of Audio:
In general, you have more deposits. You have problems with foaming, air release. You're not going to get as much reliability with equipment.
Shell Turbo S4 oils give very good performance in the Dry TOST tests showing very little varnish formation and deposit formation over the course of the test.
