I've been lurking around this site for quite a while and just love all the great advice. Now I would like a recommendation for my 2001 chevy prizm. It has about 90,000 miles on it and is my daily driver. Since I've had it I change the oil every 3000 with 5w30 penzoil yb. But sometimes I hear a ticking and was wondering if I should up the weight, or use HM oil. It doesn't burn oil or leak but this engine is a known leaker and possible sludge issuer. Thanks in advance for the advice.
