Yes Rem oil is pretty thin. I used it like water when cleaning since it's so cheap. Until I lost that tiny bottle.
Popular current products you'll hear on the web are frog lube, slide glide, slip 2000.
Oils I have used - Clenzoil, Eezox, break free CLP Collector, Rem oil, Ballistol.
Greases: RIG gun grease, harbor freight automotive grease.
BREAKfree collector is thicker but i believe the focus is that it'll stay put longer to prevent rust, less focus on lubrication. If oils, I use Ballistol sice I still have some left and I find it tends to thicken a little and stays put. But these days I end up using any generic grease for semi auto pistols at metal-on metal contact points including rails, barrel lockup points at muzzle, hood, lugs. I save my oils for cleaning and rust prevention before I put them away. None of my guns have ever malfunctioned just because they were too dry, but they have rusted before.
Finally, you will always hear about the latest greatest product and most of them work well enough. If at a loss standard BREAKfree CLP will work, and any grease will likely stick around too. I sometimes get wrapped up in the latest and greatest until I remember that my guns have worked fine without.
