What is the hottest temp your car runs at? I was just thinking that after I pressure washed my radiators from the outside the temp dropped about 7-10 degrees in all conditions and stayed much more steady than before. I did this a few weeks after I changed my tank.
I think it is the heat cycle that kills these tanks. I have a strong suspicion that lowering the peaks (via washing radiators or?) and raising the valleys (via garaging when cold, plug in heater?, other?) of that cycle would make a big difference in the longevity of the tank. It is just a theory though and I have no real world evidence to back it up.
