the oil 101 made me a believer that all oil is the same. so ever since i read it i only obsess about additives. which sucks because there is not much info on it.
here in socal the only gas with reasonable prices are Arco stations. so i always used castrol gtx on my cars. the cheaper one. with one run of the high mileage one ever few changes just because i led myself to believe it has more detergent and that it is good once in a while.
i usually change very close to advertised oil mileage life just because the oil disappears... it's not leaking anywhere so my guess is it's burning... but who knows?
anyway. does more people here bothers to match oil and gas brand because of crazy believes about the additives? ... heck for all i know it might be that all companies just pack the oil from the same source and just came up with different marketing.
taking about marketing, Pennzoil almost won me over with this site but i can bring myself to pay 10~30% more on gas by going to shell stations.
