The precision is likely not lost, just hidden. I suspect the problem is with with the display format (%10.0g) and not the storage precision, as doubles should have 16 digits of accuracy.
see -help format-, and try:

  .format <varname> %17.0g
  .format <varname> %17.15f

Is there a way to insheet 0.154143995764484 without losing precision?

I used Stata IC 9.1 for Windows as below

insheet using "C:\data\0.154143995764484.csv", clear
* It is float, %9.0g, .15414399, not .154143995764484

insheet using "C:\data\0.154143995764484.csv",clear double
* It is double, %10.0g, .1541439957645, not .154143995764484
*   For searches and help try:
