I have been reading BITOG forums for a while and concluded that Pennzoil Platium is one of the best synthetic Oils and I have also read that it is a Group III+ Base oil that is a GTL ( Gas-To-Liquid ) that is on par with PAO Base Oils, recently I have read many UOA's for Valvoline SynPower Oils and I have been impressed by the results. Does anyone know what Base Oils Valvoline uses ?
Thanks.
