Basically what I was taught when I was starting out. Stick to the right side "H" pattern and split the gears as needed.

I like to think of it as half gears when using the splitter and full gears if you have to move the stick.
I have only one site where I have had to split the low end and that is coming out of a pit pulling belly dump doubles grossing 130k and it is about 2 miles uphill right out of the gate. The other time was grossing 210k and pulling Homestake from the East. When you are really heavy going up a hill you may not be able to split because of the loss of momentum and have to go a full gear instead.
The cool part is going down a pass where say 6th high is too fast but when you split it down into 6 low it is just enough for the jakes to hold you back. -

18 speed can be driven 3 ways. As a 9 speed,13 speed, or an 18 speed. The best way is as a 13 speed. You only split the top side. On an 18 speed transmission. It is in wise to preselect the gears. That is an expensive transmission to replace.

Nice info i have yet had the chance to drive a 18spd

Thanks for the info, guys! Just to clarify, though, is it necessary to use the splitter? Or is it okay for most loads to always use the low splitter and simply use the selector to go from 4th to 5th then 6th 7th 8th?

I have a new question about the 18 speed transmission. When I was a kid my grandpa owned a Western Star with an 18 speed. He did something I've never seen or heard of since. He would start in 1st gear the split into high but did not let off the gas pedal but moved to 3rd/4th before splitting back to low. By doing this trick he did not have to float gears as the splitter acted as a clutch by "freezing" the gears. He did this by only running the odd number gears. I know this is true because his routine was always, "split", move the shifter then "split" back. Has anyone ever heard of this. I also asked someone els an he said the 13 won't do it as it will just grind if you try.
