A little motor oil question... If using only regular oil in a stock engine, would a light oil be more appropriate than 20-50? I've seen 30w recommended in a Muir book, but what do you all think will protect the engine at lower temperatures in a stock daily driver (esp. one that is primarily driven in heavy city traffic)? Currently has Castrol 10-30. I change the oil too often to use $ynthetics. >I, too, > am a firm believer in synthetics (uh, for cars, that is).

I suppose moving out of the city would protect the engine and car the most : ) but that's not an option. -- Dan Hirth Raleigh, North Carolina dhirth@mms.net 69 fastback
