I have found that I have been using Amsoil synthetics for most everything since my first experience with their product in the mid 70's that lowered the OIL temperature (by 25 degrees F in my twin Weber 40 IDF carbed 1679 CC VW Super Beetle (88mm bore X69 (stock) MM stroke that made 105 HP & 31 MPG HWY.I used to use extensively a special wiring grease made for salty environments. I was manufacturing snow plow trucks with side blades, belly blades and front blades all controlled by electronics in the cab. The grease was veryyy nice smooth sticky stuff. It was made to repel salt and water.
KYB Gas-A-Just shocks in the rear & struts in the front, 185/65 R15's Pirelli's on the front & 255/60.R15's on the rear, Transaxle had a lower first gear (from a VW bus transaxle, second was left alone, third was shorter ratio than original & the overdrive 4th was initially stock, but my oil temps would get excessive on the freeway, as the blower air cooled fan was turning to low a speed ant 60 MPG.
So out came the engine & trans and a 1.04 underdrive was put in 4th. Then it was just barely not overheating on the interstates 225-245 F oil temps.
I swapped to the Amsoil synthetic at the time & my oil temps stayed less than 225 F no matter what.
Since then, it's been my go to lube in my greasing of my boating gear, the fuel that I mix up at 80 (visible smoke free to my gas 2 strokes (boat & string trimer.
their marine grease acts like the grease that you are talking about.
