Got a L2800, running 0w15 synthetic in Ontario. My question is how long do I wait for things to warm up before using the rig? I've been told everything from 20 seconds to waiting until it is at operating temp. I typically run it at 1000rpm until I see the temp starting to rise, then work it. In extreme cold (which hasn't been a problem so far this year) I usually wait until it is up to temp.
