I suspect the problem simply is that 150 pixels wide is a very small image - I just downloaded that guts logo and then at 150 pixels it IS very blocky, and you really can't smooth it out without softening it badly.
Adobe CC uses the auto setting as default now, and I can confirm that if you take that image and shrink it down to 150 pixels width - it looks totally fine and normal AT THAT SIZE - if you then make it fill a bigger frame, there simply isn't enough data to create a sharp image on ANY preset.
What exactly are you attempting to do? It's the old story - making images bigger means creating new data which you don't have. Logos are meant to be small, and then kept small. Are you certain that when you change the size, it is not job done? Are you then expanding the magnification, expecting it to look good? It won't.
Personally I would create a logo as a vector file, using Illustrator or similar, enabling you to scale the logo indefinitely without any loss of quality, most photoshop effects can be recreated in illustrator, although some, such as drop shadow effect will be rasterised, unless you manually create it as a shape.
You can export is as Jpeg, or even import the vector into Photoshop and do what you need to do.
There are companies out there that will be more than happy to redraw your logo for a nominal fee.
