I recently changed my coolant while installing the LN low temp t-stat. For the money, I purchased OEM Porsche coolant...wasn't worth risking my engine with 15k miles to something other. You can use Pentosin (probably the manufacturer of the OEM), but there is little, if any, cost savings.

There are others that will say to use something like Dex-Cool, but the difference in price is negligible as far as I'm concerned. As far as mix, I would think a 50/50 blend would be fine, but I'm not an expert.
