Optima is a horrendous waste of money IMO.
Oh no, Why?? your gonna burst my bubble! I love the Optima for my car needs, inparticular picking up the load smoothly with my underdrive pulleys. More important than that is on 100 degree days the Optima shows no "hesitation" or slight drop in rpm's when I turn on AC Max.
I had a Diehard Platinum series and it would always directly or indirectly cause rpm's and idle to increase/fluctuate when the AC was turned on or slightly when the radiator fan would turn on. It was very slight but it was noticeable to me and I didn't like it at all. The Optima Red I have is all smooth sailing, steady idle, all the time. That is the couple of reasons that caused me to switch. I love it so far- Eight months now. Three year warranty from our local "Mom and Pops" store here.
Everybody & Anybody should read up on why the Optimums are disliked by some because they work hard for me. I would get another one again and again just because of it's capability to pick up and handle any spiked load thrown at it. i just love it here, inside the V6. I have variable that stand my car apart also- its tuned, lots of mods, 300K miles, ect...... So it's a great upgrade for this here V6 thats in need of some extra amperage supplied all the time! For me, it's the best. Thanks, and please share the other stories, not so great!!!!
