Well I have a simple regulator in line with a Speedaire moisture seperator on mine.
The way my locks work, you don't want to use an oiler on them. That's because the vent is clear back on the lock pushbutton. I ended up with 50 foot of airline full of oil.
Not sure what type of setup you have but it's a thought to consider.
BTW, I have been using these lifts now for near 20 years with no lubricaters on them and have never had a problem because of no oil on it.
