My dad has a 2007 Ford Ranger with the 3.0 V6 Vulcan engine currently at 160,000 kms and has been consuming ~1 L of oil throughout a 10,000km oil change interval. It has been doing this since ~140,000 kms. No leaks on the underside that I can find. It's a minor annoyance, especially considering the mileage is relatively low and this is known to be a pretty durable engine.
This truck was bought new and I am extremely meticulous when it comes to maintenance. This truck is not driven hard at all. Dealer serviced for the first 50,000 km, after of which I have been performing the servicing myself using synthetic oils every 10,000 km. The last 50,000 kms I have been using 5W20 Pennzoil Platinum and a Napa gold (Wix) 1516 filter. I did try a thicker 5w30 Quaker State Defy high mileage oil for one OCI about 20,000kms ago to see if it would improve things. Did not notice a difference.
So just curious for anyone experienced with this engine and if this has happened to you. Maybe it's just a fluke? Could it be a problem with the piston rings? Maybe I should switch over from synthetic to a high mileage oil over a few OCIs to see if it will help?
