| That's right, mineral oil normally used to run new engines in as fully/semi synthetic wouldn't allow the necessary wear to take place. Dave H is spot on, also Snells recommend that 600miles/1000kms is minimum before first service on a Duc - preferably longer. The key thing is not to blip the engine on first start up, let it start on a closed throttle and then use the fast idle to raise the revs to about 2000 whilst the engine warms up (that also applies to older engines too, especially non testastrettas). |
