Been using Red n' Tacky #2 on gears and Mobil One 5W30 on everything else for ten plus years. Pre-war, post-war, and modern. Clock work, live steam and electric. HO, O and Standard gauges. Everything works great. Never had a problem. For me - and my trains - they have passed the test.
And I clean my track with ATF.
And I respect what you have found to work successfully for you.
I started researching the subject after I got jumped on for WD 40. I have found out a lot in the process, more than I wanted to but its good learn about the products we use. Like I posted earlier, These items were common among RC, Slot Cars, trains, and a few other areas:
White lithium grease (any parts store)
Silicone based grease( any parts store)
grease with PTF( Teflon ) any Parts store
Mobile 1
Lucas Oil tacky red
Any silicone based oil (best)
CRC heavy duty silicone lubricant (Parts store )
