Think you're mixing up your percentages. E85 = 85% Ethanol (15% gasoline). There is no such thing as E90. You are probably thinking of 90% Gasoline and 10%Ethanol (also known as E10).

Which is why, when you do use tantalums, you use ones that are specced at twice the voltage you expect over them.

We've used tantalums in some telecom equipment we make, and except for about 5 spectacular failures (explosions, fireballs) on some early prototypes (because of wrong part numbers and such), we've never seen a failure in almost 7 years.

We could not have used electrolytic caps as they would not have survived as long.

BTW: reverse voltage an electrolyte, and witness the explosion (and foul smell) also.... Used to do that to scare people in electronics class.....
Of course, if we redesigned now, I'd probably change out some of the tantalums with ceramic caps.

My family has diesels in Norway (German Fords, 1.8L TDI). Latitude approximately Anchorage AK.
The cars have a secondary heat turbine that is used as a engine heater to get the engine to starting temperature in the morning, and to INCREASE the coolant temperature if it is too low.

The cool thing is that this turbine has its own timer so you basically have a mobile block heater with you at all times...
