I think engine oil change intervals are way too short for modern synthetic oils.

Three years ago I switched my Honda Civic to full synthetic and started changing it every 10,000 miles like the manual says, but last month a mechanic in Phoenix told me I was ruining my engine by going past 5,000 miles, so has anyone else actually run a UOA to back up the old rule of thumb?

Oh yeah, that's exactly the advice I got too.

People act like one bad piece of advice is going to ruin everything, but life's full of wrong turns. Chances are you'll forget about it in a week anyway. Is it really worth getting worked up over?

Oh I hear you, that mechanic's take is SO outdated.
