I now have 25+ hours on my new 3300 Gen 4 and am having an excellent operating experience! I did the first oil change at 25 hrs and was pleasantly surprised to see that the oil analysis came back with all parameters (especially wear metals) normal! I had expected to see some elevations in metals as this was a new engine and sometimes elevated metals are seen initially due to remnants from the manufacturing process. Also, the engine seemed "broken-in" from hour one as there really wasn't any high cylinder temps, high oil temps, or excessive oil consumption. I understand the engines are dyno tested at Jabiru before shipment and then the oil is drained for shipment. So, just out of curiosity, how long are the engines run on the dyno and are they just tested to be to spec or are they also run through a break-in routine? Seems I got a really "clean" and broken-in engine! 🙂

Glad you are happy with your engine. The engine is run for about 1.5hrs on the dyno. Part of that is the run-in, part is checking it meets specifications. It certainly hasn't completed its run-in when it leaves here but probably the initial high wear has been done. Do you intend to conduct oil analysis at every service?
@jabiru-support Yes, I always do oil analysis at every 25hr oil change. Thanks for the info!
