You’re definitely not alone. My first teacher who pronounced “oiler” correctly did so a lot and every time in my head I had to deliberately pin the sound to Euler because I had heard the name mispronounced consistently for years.
Eu is an old and common long diphthong prefixing Greek roots to mean “good-{whatever}” with lots of cognates in other languages pronounced with a long u sound. That Euler should be the rare exception is fitting, but most who read the name first will mispronounce it as a result.
