Whats the difference in synth and turbo oil changes?

I just moved and my new local Mazda dealer has already found me... lol They sent me a coupon for an oil change that I just dont understand. It says the following;

STND: $24.95 SYN: $44.95 Turbo: $69.95

My question is, what the hell his a turbo oil change and why is it $25 more than a synthetic oil change which is what I usually do, mobile 1 full synth.
