87 or 90 what burns cleaner?

[Gjkrisa]

So I'm curious I know 87 burns faster then 90 and curious if during cruising speeds if 87 burns cleaner also live in the city. So lots of stop and go but really short trips like 20 miles a week maybe. Really an electronic car would be best for most of our driving but those good ones are out of our price range.

Octane is the ability for a fuel to resist pre-ignition period

Well if u didnt know already, Tesla has been taking preorders for their 35k all electric car for a month now. Waiting list is HUGE tho.
