Ron Ananian, The Car Doctor - October 11, 2025 - Hour 2 - Battery Drains, Gear-oil Myths & Two Diesels That Won’t Behave. - (855)560-9900 24/7 Hotline

Ron walks a caller through the right way to measure parasitic draw (use a real meter with min/max and leave it connected), then tackles GL-4 vs GL-5 confusion on a ’99 Sentra—plus where to find stubborn drain plugs when OEMs say “obsolete.” We hit hybrid maintenance realities with a ’22 Prius CVT service, a cold-start 7.3 Power Stroke that likely needs cleaning for stiction and better cranking strategy, and a 2017 Colorado Duramax with a first-gear slip that may respond to additive—before facing the cost of a rebuild. Ron also flags industry ripples from parts-maker bankruptcies and why cheap, mystery-brand components are costing drivers more in the long run.
