Optima - Blue, Yellow, Red, or Purple?

go for the yellow one!

I worked for Cabo Yachts for awhile (the Mercedes Benz of profesional sportfishing yachts 500K and up) runing dual turbo diesel caterpillars 700hp + and the yellow tops were used exclusively. I bought one from Cabo at a discount in 2004 and its been used in two vehicles since then and is now in my built 40 w/350 vette engine. I live in whats called extreme weather 118 in summer and teens in winter. My 40 also starts right up.

I have a red top that was sitting for 2 yrs during my conversion. Recharged it and it starts my vortec pretty solid so far.

I only wish I had the same luck as both of you.
