Linear Guide Rail Lubrication

Hi Guys, I was wondering what are you using to lubricate your linear guide rail, oil or grease? How to do apply it?

Thanks for your help.

Heavy Duty Silicon lubricant that came in an are-sol can. Bought at walmart. It was in the automotive section.

I have central lubrication and use 20w40 engine oil for it

I use white lithium grease.

On my laser, 3-IN-ONE

On my CNC Spindle, similar to @Andreas, I have centralized lubrication and just use 0W-20 Mobil 1 or 5W-30 Mobile 1 (because the cars do).
