Yesterday, I went to an Ace hardware store called Westlake's and bought some high-quality turbine oil called Zoom Spout. Thanks to Scott Dorsey for recommending this oil to lube the nooks and crannies of the Michelin floor jack. This turbine oil was hard to find and I only found it because Scott mentioned Ace hardware.
3-in-1 oil is everywhere, but turbine oil was only at Ace, not even Harbor Freight.
While at Ace, I also picked up some 220-grit sandpaper and indoor/outdoor enamel paint to fix up the small rust spots on the floor jack. The Sam's Club Michelin floor jack is wonderful, works awesome, and has lots of great features, but I really wasn't expecting a handful of small rust spots. Anyway, I'll take care of that jack because it'll take care of me. I'm trusting that jack with my life, after all.
I went back to Harbor Freight to play with the 5 or 6 floor jacks they have on display. Not even their aluminum jacks work as well and as smoothly as this Michelin jack from Sam's Club. I actually think the Michelin jack is made by Shinn Fu America (must be a Chinese company), because Shinn Fu appears in very small print in the manual. Michelin musta paid an advertising fee to get its name and logo emblazoned on this fine jack. Everybody knows Bibendum, the Michelin Tyre Man! He's the buff version of the Pillsbury dough boy.
The convenience of the jack's Speedy Lift feature really can't be overstated. None of the jacks at Harbor Freight had this. Ray O, I'm wondering if your old but reliable pro-grade floor jack that you bought from a buddy has the Speedy Lift feature, which brings the saddle up to the chassis in one stroke? "They don't make things like they used to" is often true, but I wonder if Speedy Lift was around at the time your jack was made. Your jack is probably built better than mine, but I doubt it has Speedy Lift ;-)
I wasn't able to find the hydraulic jack oil recommended by the manual anywhere. Everybody's got a generic hydraulic oil and the Snap brand, but I couldn't find the Mobil DTE 13M mentioned in the manual anywhere, or the synthetic Pentosin/Pentosyn CHF 11S recommended by Steve W.
