Just about to lube my touring car for the Texas T Party. Most things (spindles/shackles) are lubed with motor oil.
I remember a really slippery product that I used to add to the oil on my old worn-out Dodge. It was called STP Oil Treatment. That stuff was really slippery. I was wondering if STP by itself could be used to lube these chassis parts instead of motor oil. Has anyone ever tried this?
Chain-bar or a rear end oil works. You want something that sticks and still has some flow. STP mixed with a little motor oil should work fine.
STP is not oil.
Any good heavy oil will do.
I use the chainsaw bar oil for all that stuff. It's really sticky!
While there are currently several different products under the STP logo and are auto/truck fuel or oil related. Why is the standard STP oil treatment not an oil?
You might want to talk to the wood cutters or suppliers in your area for some "summer grade" bar oil. There are a couple of grades of bar oil out there. Summer Grade is considerably thicker and sticks to moving parts better. Winter Grade is lots lighter stuff. The all season grade seems to be lighter stuff as well. I can usually get summer grade stuff at those places that specialize in chainsaw sales and maintenance. Hard to find at the others.
Use vegetable oil, it's bio-degradeable and non-polluting.
STP is mostly a viscosity modifier, not an oil.
I ran out of chainsaw oil and started using the 600w oil the vendors sell for the rear end. It seems to cling and works very well.
Because of its thicker viscosity, my kingpin oilers won't flow motor-oil—the stuff just sits there in the little cup and goes nowhere. -Now I give them a steady diet of 3 in 1 oil. -That seeps through okay.
The rest of my oilers flow easily, so they get whatever weight motor-oil I happen to have at hand.
Bob, that's because you have new tight king pins. Give them a little time to wear in and the heavy stuff will work just fine!
Some people cheat a little and have interchangeable grease/oiler fittings. Thread in the grease fittings then replace with the standard oilers.
But don't use grease on the spindle bolts, unless you add an additional fitting for the lower bushing.
I've used straight STP oil treatment in all oilers except the generator for 10+ years. My Dad, who I got the '26 from, talked me into it. STP works through more quickly than I expected but not as fast as motor oil so it drips less. Everything stays "oily" and slippery. I make no claims about scientific justifications for this or lack thereof. ;-)
Chain-saw bar oil is what I use in every flip top oiler on the T. Cheap and just right properties make it a no-brainer. Works very well in my ford script under hood oil can.
