It's possible to change the database configuration to support 2 and 3 letter words for search since the forum just uses the database for it's search results. Most forums have this same search limitation as well as crappy search results because it just uses the database to search and not any smart algorithm or anything intelligent so results are usually like the ones you'd find on Altavista search engine in the 90's or something.
The workaround is if you really want to search the forum, use your favorite search engine search for "site:
https://tacoma3g.com/ Engine Oil" and you'll get all the results you were hoping for and then some.
There may be a plugin or code modification to replace the forum search engine with an external call to google or duckduckgo or something. That way you can still use the forum search box to perform your search but get way better results and the ability to search 2 and 3 letter words and acronyms.

as for answers to the questions
1- I love that this community seems to be one that values integrity and empathy as well as liking the outdoors, our trucks and off roading. This community actually feels welcoming which I suppose is rare these days. So thanks!
2- Keep up the excellent work. I'll try to find a search improvement that might work for you
@Tyler but other than that, you're doing an awesome job and you've taken previous suggestions and implemented them so rock on
