I'm thinking the difference is in the tube between the 230/250/292, in that the 292 has a shorter tube for the dipstick. Anyway the only dipstick I have is for a 292. From the stop it measures 13 3/4 to full and 14 3/8 to add. If you can't find another in Norway and want to pay for the ride let me know.
