I ignored the OLM since we bought it and change at around 5000 miles. And, for most of it's time with me, it has only gotten Pennzoil conventional 10w30. 12 years old now and not a hint of a problem with this engine. Car is great shape, so we are keeping this car for some time more. One reason is that tag renewal and insurance now is cheap! Only $50 a year for tags now.
TT, is 10W30 PYB the same oil you run in your Dexos 1 vehicle? I remember you saying you ran a 10W30 in it. Not knocking your choice. Was just curious. Thanks.
