Is your vehicle standard?
I assume if putting it in N it is a manual not an automatic.

Do you know what Octane scale you use?
91 octane in the USA at least, would be about the same as 95RON here in the UK.

I'd suggest over 40mpg is not the norm for most Jimny's. You really do need to drive it very gently to attain that (never managed it in mine, even when 100% stock).My very standard gen 4 still achieving a lifetime average of over 42mpg (UK). No motorways near me but otherwise regular A & B road driving. I rarely cane it though.

No, neutral will be at idle and still pumping fuel in. Using engine braking will be no fuel and potentially more economical.
Great theory, but in practice coasting in neutral uses less fuel.Driving down hill in neutral that is coasting is not good. First it reduces your control of the vehicle as you have no engine braking effect which in turn increases reliance on the wheel brakes which can cause them to overheat. Secondly the engine will revert to idle in neutral which requires it to burn fuel, when going down hill in gear the ECU detects this and virtually stops fuel supply, the effect may be small but it does increase mpg.

i was going down in N, my car is automatic, i will take into consideration what you told me, knowing that modern cars have more stuff included it may be true that going down in D stops fuel injection, i just had not thought about that before, thanks
