I use Lucas in my multi vat ultrasonic cleaner. It was available in bulk (5 gal container for about $100). That makes it the cost effective to use (about 15 cents/oz). I have many different oil and grease brands, viscosities, sizes and shaped containers on my bench. Except for the bulk needs I tend to reach for the applicator that best suits the job at hand. Some jobs need a drop of oil, a toothpick of grease, a capillary of refrigeration (very light) oil or a light coating of what ever is handy. There are no magic potions that will last indefinitely. For those with limited space, Wilson Combat offers three viscosities in convenient size and shape applicators. The oil/grease is no better, no worse than any other, just convenient.
