Can someone confirm a vehicle uses more fuel in wet and windy weather than in dry

[Nicola H]

calm, conditions.? please someone settle this argument, I stated that I use more fuel when driving the same route and the same speeds, when it's wet and windy than in dry and calm conditions... it all being down to wind resistance (drag) and that the engine had to work harder to reach the speed I asked from it. I was told I didnt know what I was talking about. I argued that if I had the wind behind me all the way I wouldn't use as much .. a little like uphill and downhill.. I was in fact laughed at ..he apparently had studied for 4 years and stated a vehicle uses more fuel on a hot dry day with no wind ..according to him something to do with traction .. which hadn't anything to do with my initial statement. Come on you people in the know lay this one to rest please. Apologies to Antonio If I'm totally wrong ..I am but a mere woman.

Yep, it certainly does. I used to drive lorries and the difference in mpg on a bad day was staggering, so presumably, it must also affect other vehicles but to a lesser degree.
