The preivious note and your note are 2 different problems. It is likely from my experience that you are running overheated. Several things will casue this symptom. In both cases, oil thins as it gets hot, setting off the senders. In both cases the best think to do is to innstall a temperary oil pressure gauge and ensure the low pressure warning is not a resault of a bad sender, first.
