I have an 02 Electra Glide Classic that just turned 40K miles. My oil pressure has always sat at 32 psi when going down the road and near 0 at a stop. Two days ago I went for a ride and the highest the oil pressure would go was about 16 psi. Oil level is fine, oil and filter were changed about 300 miles ago. Any ideas as to why oil pressure that has been consistent for 4 years would suddenly change like that?
