Maybe due to different alloys used in recent crush washer stock. You should be able to feel the washer compressing --- a tad --- as you tighten the bolt. This is with an unused washer.

 

This is just my experience, never used a torque wrench to do this, replace crush washers every other time, hand tighten both filter and oil pan bolt...never had an issue with any car....just make sure it is tight then turn it a fraction of a turn, both. Your mileage may vary, this is not rocket science demonstrated by the amount of oil change places there are. Always do my own on my S2000, its never leaked any oil I can detect, since new, now 13 years old.

 

If you never heard of it, there is a sealer I've used for many years in my Ferraris, Jags, Porsches. It was developed by RR and it's called Blue Hylomar.

 

Back from the dead! I am game.

Of course you could install a Fumoto and never be concerned about that again. Super easy to drain as much as you want.

Learn something new everyday.

 

30ft lbs on every single Honda and be done with it.

 

I'm a little more careful with alloy-panned engines than the steel ones.

But, that's me.

 

still 30ft lbs. as per Hondas recommendations steel or aluminum . have done hundreds of oil changes and never stripped one

 

Careful initial hand-threading of the bolt, is the key to happiness!
