When I first got my 2021 RAV4 LE it was new from the lot with only 10miles and they added a full tank of gas (maxed 400miles to empty).
For a few months it's always been 405-390 in distance to empty, however this past May, I noticed that my distance to empty only maxed out to 370miles (full tank almost had gas spill out). Does that mean I have my tank kinda dirty or it's just because of everything going on (political gas changes or Summer heat) that it automatically takes it as 370miles and not 400miles?
Sorry I know this may be stupid question but I was just wondering. Plus it's my very first new (off the lot) car and I want to make sure everything is okay.
