When I am at a stop and just idling my oil pressure drops down into the low range, then when I start to go, the pressue goes back up to normal. I just changed the oil and filter and everything is on tight and the dipstick shows enough oil. Could it be because I used to light an oil (10w-30), should I have used something heavier like 15w-40?
