\r\n \r\n Sry, I don\'t check new threads too often..lol I use valvoline or castrol only. One oil change isn\'t gonna hurt it. I had a 78 pontiac bonneville I bought from a doctor dude, one owner, had every record of every cent ever spent on it. Oil changed 3000 miles or less...penzoil. I spun a rod bearing, pulled the valve cover you could shovel the sludge w a spoon.....no joke it was like 3/4 inch thick. Never used penz since. Just check to see if it says perathane (sp) on the bottle, that means wax.\r\n
