Does normal mode use a lot more petrol than economy mode?

[thisguy]

I’ve mainly stuck to economy mode, in my 4 cylinder Camry. Lately I’ve used normal mode for a couple of return trips down a few kilometers of highway, doing 80 to 100. This past week I’ve spent twice as much money on petrol as I’ve done in past weeks. I’ve been using 95 RON.

Could using normal mode make that much of a difference? Or maybe I’m just accelerating too quickly.

The harder you accelerate, the more fuel you will use. Anyway, when you drive for a bit of fun, don't care about the fuel economy, just enjoy. Most important thing is to drive safe. Had to accelerate out of the way of an idiot driver who was not smart/patient enough to merge behind me rather than into the side of my vehicle. So much for the fuel economy.

I must admit I put mine into normal mode on the highway because I don’t want some idiot tailgating me.

So a preventative measure and peace of mind has probably "cost" you a tankful of petrol. Accident with an idiot is going to cost more plus inconvenience.
