BMP085 fluctuating readings

Pressure readings from BMP180 fluctuating. Data shown on serial display reads...

Temperature: 26 deg C Pressure: 101170 Pa Altitude: 58.96 m

Temperature: 26 deg C Pressure: 101164 Pa Altitude: 59.46 m

Temperature: 26 deg C Pressure: 101170 Pa Altitude: 58.96 m

Temperature: 26 deg C Pressure: 101162 Pa Altitude: 59.62 m

Temperature: 26 deg C Pressure: 101170 Pa Altitude: 58.96 m

Temperature: 26 deg C Pressure: 101164 Pa Altitude: 59.46 m

Fitted 10k I2c Pullups, Changed oversampling value, still fluctuating. What have I overlooked ?

That looks like normal sensor noise to me, but consult the data sheet for the sensor to be sure. If it is typical, average some number of samples to get stable readings.

Thank you jremington.
My first try with Arduino, migrating from Pic. Ultimate aim is to use BMP085 as a depth gauge on a container of oil and water.
Can’t use a float. Tried magnet in a float in sight gauge tube, problem with float volume required to support magnet weight and float sticking in tube. Figured if I seal top of sight gauge tube, pressure to depth could be calculated by trial and error.

The noise on that sensor corresponds to about 1 metre of altitude. If you take many samples and average them, you can discriminate difference in altitude of about 30 cm.
