I have had a look throug this thread on diesel fuel issues. It can get quite cold at times. Imagine if all the diesels got stuck up on the ski fields. BP say their winter diesel is good to minus 15c. After that pour in some additive or jetA thats good to minus 40c. Add 1 percent oil for pump lube. Diesel is quite different to fly. Well mine is. Take off revs do not exceed static. That will be pump governor setting, torque increases as RPMdrops, only 3 or 4 hp loss as RPM fall 3 or 400 RPM. Propeller changes will be interesting. Chas
