DIY oil tank

["atrav" <atrav@copper.net>]

For one of the motorcycle projects I'll be welding up an aluminum oil tank. 
Since 5052 0.050 or
0.060 aluminum seems to be the accepted thickness for gas tanks, is that OK too 
for an oil tank?
I'm wondering as the oil tank will see a much higher temperature swing, if 
thicker would be better.
It won't be formed much, so I don't need the bendability of the thinner stuff, 
but I have a bunch of
0.050 left over...
