well I went to Moble1 15W50. I am stuck in ALBQ right now on military duty so I cannot crank on any major miles. I have placed about 100 since changing, without seeing any loss. I should have another 1000 on her by the timg this deployment is over. That was the distance I was sucking down a quart. I would never leave you guys in the dark!!!
