2009 honda civic type of regular gas can it use

[vagabond48]

Several months ago I bought a 2009 honda civic 1.8 fitted that also uses LPG. It also came with a 1/2 tank of regular fuel which I will need to refill soon. I know this model uses E91 but can this 2009 civic safely use lower priced E20 as well? The car did not come with a manual. We also plan to do some traveling and I may need to use my regular gas if there are no LPG stations around.

Thanks

Use E95. Thats about as low as you can go price wise. So my Chum with same year, recons 91 runs rough in traffic.Second hand info though.
