the sp-ii and sp-iii, etc.. are very compatible with +3, +4, etc..
I flat out asked the mitsu parts guy what the difference was and he said he didn'tknow, of course. He said the shop uses +3, they sell the SP-III for over counter customers.
I've used +3 in the eclipse.. shifted just fine.
The last time i used +3 in my other Mitsu, the valve body solenoid (or shift solenoid, i forgot) went out in 10k miles. I don't know if its related to the fluid but the car only had 60k at the time.
