I Designed My Own Oil Cap for My Hondas After Getting Tired of Slippery OEM Caps
After years of working on Hondas, one small thing kept bothering me — the OEM oil caps can be surprisingly annoying to remove when your hands are oily during oil changes.
A lot of aftermarket caps looked good, but many of them didn’t actually improve usability. Some even felt worse than OEM.
So I decided to design my own.
My main goals were:
- Better grip with oily hands
- OEM+ appearance
- Precision-machined feel
- Something that actually feels good to use repeatedly
I’ve been testing the design on my own cars for a little over 2 months now (around 3,000+ miles), and I also gave prototypes to 3 friends who daily drive their cars and do their own maintenance.
So far the feedback has been very positive. The biggest thing people noticed was how much easier it is to remove compared to the OEM cap, especially during oil changes.
Still continuing long-term testing, but I wanted to share the project with fellow Honda enthusiasts here since this community appreciates functional details more than most people.
Would love to hear your thoughts or feedback.
