Can you promote in r/mechanicadvice?

This is more than a car repair forum! Please read and follow the posting rules listed in the right hand sidebar.

The short answer

Do not mention or promote your product/company; instead provide direct, helpful technical answers and only participate as a regular user without linking or pitching.

What works here

  • Answer on-topic mechanical questions helpfully and courteously
  • Follow Q&A format and include vehicle year/make/model/engine when relevant
  • Post diagnostic images or germane links only when directly relevant to the OP's question (non-promotional)

What gets posts removed

  • Mentioning or promoting your product, service, app, channel, or business
  • Posting promotional links, offers, coupons, or unasked how-to content
  • Using comments or posts to solicit customers, leads, surveys, or recruitment
