What brand and weight of oil do you use in your Volvos? I have been using Valvoline 10-30 for the last 6 years. Was talking to a Volvo mechanic yesterday who said he uses only Penzoil 10-30 and that he thought the Valvoline breaks down quicker. I live in the south where summers are hot and humid and winters are fairly mild. What are your opinions? JB (remove parenthesis on reply address to reply directly)
