I like the occasional squeak or grunt as stock moves slowly through a point network, but wouldnt want continuous squeaking!
I started using GT85 plastic compatible PTFE spray sold as bike lube about 15 years ago, to ensure really free running* of Bachmann and Hornby RTR OO stock. One application seems to last forever. I have recently started on my second can, so very economical, as the applicator tube means a tiny puff can be put in each moulded recess with no spill. No evidence of any plastic degradation or paint damage, (good job as it is now on many hundreds of models). I have been informed that the model helicoptorists and dronists now have a yet more slippy formulation, which I would like to try, but looks like I won't be trying it until about 2030...
*The first model railway club I joined there was an insistence that all stock must roll away when placed on a true 1% (1 in 100) gradient, and ideally do better than that, which minimum standard I adhere to. I run all new stock for a couple of hours 'dry' first - sqeaky, squeaky - then apply the GT85: current RTR OO metal wheeled stock then typically gets away on 1 in 200, and the best RTR OO I have experience of will do better than that without any added lubricant, some better than 1 in 300 (Bachmann pinpoint pick up coach stock and MU's, plated pinpoint running in what looks like formed phosphor bronze 'dimples', and Accurascale wagon models, steel pinpoint in moulded plastic dimple) which is pretty close to prototype.
Oh, and rolling noise is the roar of metal wheels on rails, no squeaky axle bearings.
