This is my added question to this conversation.
When I was a young 16 year old punk kid, batteries had 5, 6, 7 year warranties and would last the 7 years.
Today you are lucky to get a 2 year warranty and are evan luckier if it last the two years.
What the hell have they done to batteries to...
I can not find ethonal free gas near my house, even with two lakes 15 minutes or less away.
I run 93 octane in all my equipment. I also run it with the fuel shut off till it dies(if it has a fuel shut off).
I have had very few problems.
