Last car I purchased new (1992) went through two engines and has 475,000 miles on the body - current engine was used so can not say how many miles total on it - 1st engine crapped out around 400K. 

The station/fuel I used probably 95% of the time in that one was not on the list of super duper fuels.  Have only had one car in my life not make over 100K without engine problems - and the cracked head on that one I do not think had anything to do with the fuel.

Newer vehicles are made for 10% or more ethanol, same as diesels that now are made for lower sulfer - run the new diesel in old stuff like farm equipment or older car/truck engines and expect to have problems with leaks - the seals are not made for it.  Same could be said for older cars that used lead fuel additives - newer cars are made to run without it, older ones it would eat the valve seats up.

Only thing we ever had that really cared about fuel was a V6 92 chevy truck that would only run right on Chevron premium - anything else or lower octane and it would diesel on shutoff and the cheaper stuff you could watch the needle drop when driving.

I try not to put ethanol in lawn equipment or boats just because they may sit for periods of time between uses.
