DEAR DOCTOR: Kw_own I a Dodge Stratus Kw_sixzylinder 2001 with 28.000 miles. I bought it again and using to oil 5W30, for which I change all 3,000 miles. If the engine is hot and I come to a notice, the oil light flickers. If I sit by a long traffic light, the oil light to constant remains to I pull away. It was suggested that I switch to a 10W30, although the manual 5W30 in the cold requires more weather. It agree? Jack DEAR JACK: Before you change oil viscosity, keep the oil pressure examined with a mechanical theory at each good repair workshop. The problem could be incorrect oils pressure switches or one weak oil pump. A change at a heavier weight oil box sometimes increase the oil pressure enough, to the oil light out in hot no-load operation to hold. Concerning the no-load operation: Is the no-load operation speed at the correct specification? They can also switch to a full-synthetic oil, which is without 10W30 all possible interests using.
