hi. i am buying a 1994 acura integra with 126k miles on it. very well maintained. a reciept book a mile long. it is getting cold here in omaha and i am looking for an oil reccomendation for the winter. i will probably put 30-35k miles a year on this car and want it to last a good long time. i looked at the recent oil filter study and am leaning toward a pureone filter. i know that they dont flow as well as other filters but i tihink that it is an okay tradeoff. how low on oil pressure would be too low? should i be looking into 0w30 oil? i have never used 0w oil in anything up until now. any advise?
