Additive TC-W3 synthetic lube added to diesel
, protects top end of engines against the wear of the terribly dry ULSD diesel
... Well proven, just cannot add to modern EPA type vehicles with AdBlue or DPF exhausts...
Anyway, it has been hard to determine due to my lazy record
keeping and using the genset to... But I am figuring about 2.5 litres per hour at sort of 2000-2200 rpm
cruising, and more like 3.5 lph at 2400-2500 rpm. With a clean bottom and not bucking wind
my Helia 44 will do 7 knots on one engine.
I have added the optional 470 litre tank on Starboard, and pump
across when the main tank is down 1/4 or 1/2... On my way home in a weather
window last year when I had to get back: I have done over 650 NM in ten days of no wind
and pretty much flat seas on one tank.. Trolling, fishing
the whole way, caught about 20 fish
.. zig-zagging to see sights and whales and floaters. That run was with some minor 9.5 kva Cummins Diesel use at anchor
, plus anchoring
at islands every night and anchor
retrieval in the morning, so, yea... Range on one tank is probably 650-700 NM with NO sailing... hmmm
