What factors affect real-world fuel costs on a used hatchback?

As someone who works extensively with deep learning models, I'm always seeking new deep learning insights that can improve my work. Some deep learning insights I've gained recently have completely changed how I approach certain problems.

One particularly valuable deep learning insight for me has been understanding the importance of data quality over model complexity. What deep learning insights have you found most transformative? Any deep learning insights you think are underappreciated?

One deep learning insight that completely changed my approach was about initialization methods. I used to not pay much attention to how weights were initialized, but understanding the deep learning insights around proper initialization made a huge difference in training stability.

Another transformative deep learning insight involved regularization techniques. Learning which regularization approaches work best for different types of problems and data has been one of the most valuable deep learning insights I've gained.

For me, the deep learning insight about the importance of batch normalization was transformative. Understanding this deep learning insight about normalization techniques really improved my model training.

I think one underappreciated deep learning insight is about learning rate schedules. The deep learning insights around adaptive learning rates and scheduling strategies have made my training much more efficient and effective.

The deep learning insight about transfer learning has been huge for me. Understanding that I don't always need to train from scratch, and can instead build on existing models, was a game-changing deep learning insight.

Another deep learning insight I think is underappreciated involves attention mechanisms. The deep learning insights around where and how to apply attention in models have really improved my results on sequence tasks.

I just bought a used hatchback and I’m trying to understand my real-world costs. The advertised fuel economy was great, but my first few tanks of petrol have been way more expensive than I expected for my commute. I’m wondering if my driving style or the type of roads is causing this.

I bought a used hatchback and yeah the first few tanks felt pricey until I realized city driving with lots of idling can burn more fuel per mile than highway cruising.

I started logging every fill, miles driven, gallons, and cost, then calculated cost per mile. It helped me see where the extra money was coming from.

Check basics like tire pressure. Underinflated tires really kill mpg, and a heavy roof rack can push it down.

A dirty air filter, stale fuel, or a misfiring cylinder can wreck efficiency. I swapped a clogged filter and saw a small bump.

The advertised economy is often on a highway with steady speed. Your commute is probably mixed, with stops, hills, and cold engine. Those all matter.

I also tried a couple of different routes and noticed hills and traffic lights impact the cost more than I expected.

Do you track a full fill mpg and cost per mile?
