Idle at 20mph
Theres a side road I usualy take on my way to work...minimal stops, and minimal traffic.
The speed limit is 25mph. I found yesterday that my car will hold 20mph when I take my foot off the gas. The engine drops back to idle (like Idle in drive at a stop light) It shifts to 2nd gear at about 15mph under slow accleration.
Is this a more efficent than keeping the throtle open to hold 25mph? Because the RPMS drop from like 1,500 to 800ish
