Anyone have a rule of thumb for diesel consumption on a volvo 2030?
Scenario: motor sailing, 2,500 revs
Thanks,
Phil.

Rule of thumb for diesels is 1 gallon per 20hp per hour. Approximately.

24hp motoring 6½ knots (hull speed) ½gal/h max (incl eberspacher), Motorsailing / battery charging SFA - don't motor sail and rarely need to "battery charge" using engine only.

About 3 litres per hour average.

2,500 revs seems a bit high, and your fuel consumption will jump by about 1 ltr per hour reduce to aprrox 2000 rpm and you should use less than 2 ltr per hour (mine averages approx 1.7 ltrs driving a 36ft hull 5.5 tns at approx 5.5 knts)

Small Boat Champ's table sounds spot on.
We have just used 10 litres for approx 7 hrs under power for a Yanmar 2GM20 in a Hunter Channel 323 over a 3 day period or approx 1.43 litres/hour (chart shows 1.5).

The table is based on others data supplied to me from their observations.
I must update with the extra info ... I have been given ...
I prefer such a table - as it is based on actual use - not calculated expected .... much more practical and useful to any of us to plan with.

Well, I had the distinct embarrassment of running out of fuel last week. My previous estimate of 2l/hr at cruising speed proving to be inadequate for a non-stop Dartmouth to Dover run (the engine died just south of Hastings). Anyway, gave me the opportunity to refine my estimates of consumption.
Some data for your table. Victoria 34 (28' 4" LWL), 7000kg, Yanmar 3GM30F, 27HP, 90l (100l?) tank, 6.4kts, 3000 rpm, flat water, some headwind (F2-3), c. 2.8l/hr; 5.5kts, 2200 rpm, c. 2l/hr; pootling up and down the river, c. 1l/hr.
