I have a couple questions:
1) My dad uses 10W30 in the winter and 10W40 in the summer. The manual recommends 10W40. Is he wrong in doing what he's doing?
2) Sometimes when coming to a stop, my RPMS become erratic (I hear a "gearing" noise, and RPMS go up and down between, say, 500 and 1250 and sometimes even more extreme, and sometimes I have trouble with warm starts (RPMS fall and I have to hold the gas in a little to keep it going to get it started) Is there a problem here? The car idles between 750-1000RPM.
