really, a lot depends on the ambient temperature, but on any engine it is a good idea to start easy. I have the good fortune it is nearly a mile to get to the main road, and then another 4 to the freeway, so plenty of time to warm up. This morning, the oil was 71f at start up
And what gradients do you encounter in those distances? For me I have a steep driveway, 1/2 mile of flat and then all uphill to the markets in one direction and 5 miles of flat before freeway speeds going the other direction. So very different warm up times.
