Always burn the mains first.  This is a common misconception.  See the POH.
This is true for Cherokee 235's and Cherokee 6's.

In fact, you are supposed to fill the tips before you fill the mains.  It
has to do with the bending moment of the wings.  It is counter-intuitive,
but true.

  I was wondering why you would not use the Tips first? I was advised that
it is a lot of weight out there on the wings and better to land with the
tips Light Less Strain on the Wing (think of a teeter totter)

    Parked on level ground . . . . .  BTW its a 1965 if that makes any
difference. And of course "I just say no". My wife also confirms the fuel
usage/levels. She remembers yesterday how we left it parked, halfers on the
mains and tip topped off.

        Ok, everyone, here's one for ya'll,
        Sunday I flew back from SBP to RHV, had all the tanks topped off at
SBP.
        Only used the mains on the 1:15 minute flight back home with a
slight
        headwind. Tip were full. parked and tied down. Today, Monday, this
evening,
        headed out for a quick flight with my cousins, besides being a stain
mess on
        the ground, my right main was now full and the tip was completely
empty.
        Like it leaked out of the vent of the right main tank. Has anyone
ever had
        this problem, this is the second time this has happened. The first
time it
        happened, the weather had gotten warm and I thought the main just
vented, so
        I thought nothing of it. HELP !! Before I have the mechanic start
the clock.
        You input would be greatly appreciated.

      Even if you had a faulty valve, I don't know how the fuel could drain
down to the valve (if it was parked in a slant).. and then  back UP to the
main. I can probably explain why you think this happened but it would
require your taking a drug test ;-)
