Sul or optimax will make the car run smoother, and may give it a tiny bit more punch. You should gain a better mpg figure. I gained 3 mpg by changing from nul. The MY99 unit should adjust to the new fuel after 2 or 3 tankfulls. Hope this helps

Got my Scoob (MY99) bout 3 months ago - ran on NUL til a few wekks back - no probs. Now switched to SUL to trial - no noticeable performance or running difference : just really doin it to compare mpg. I hear yer supposed to get around 10% more mpg with SUl which allegedly offsets the cost....
I believe the MY99 ecu doesnt need to be reset on fuel change - just detects and adjusts automatically....
