But what is confusing me is that unless the spring is going bad, the piston
ought to remain at the same level while at a constant speed. Since my
dashpots go through half of their oil in about a week or two, I'll be
experimenting. A representative from a local parts vendor suggested using
ATF, so that if a problem developed that caused dashpot oil to be consumed
rapidly, the resulting smell (stench) would indicate the driver.
If the oil is too thick, doesn't it also impede performance by making the
mixture adjust more slowly?
As for the 3-in-1 that I use, its best feature is that it comes in a small
can that fits conveniently behind the frame member in the boot.
