Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

That's normal. Even running 5w-50 oil in both of my car engines first thing I notice after a 5K mile oil change is how much quieter the engine is after the oil change. Looking forward to changing the coils in both cars soon. I'm hoping to notice the engine responds in a positive way to new coils.
