Hey Jason...This page explains the difference

You dont have to worry about the
oil pressure..thats handled automatically.
The manual option you have to turn on before starting the engine..that then pre-oils.....and off when you're about to switch off...that keeps pressured
oil in the accumulator ..all ready for next you start.
Now..hurry up and buy one....try it and if it's any good....I might get one.
Nuffin like having a guinea pig try things for ya.
