Not sure if this has been mentioned but thought I'd put it up here as a warning just in case it hasn't. I was speaking with a friend on the w/end who runs a 4x4 mechanical workshop and he mentioned that they just got a warning about oil changes on these vehicles, so I searched the www and found this on " Aftermarket 4x4"
Mazda BT50/Ford Ranger Oil Change Issue
Posted by Woody on Apr 02, 2014 .
If you own or know someone that owns a new Mazda BT50 or Ford Ranger then this one's for you! We recently received a service warning for mechanics about a possible issue with the variable flow oil pump fitted to the new generation 5cyl Diesel UP0YF* engines.
Rather than having a conventional fixed flow oil pump, the new engines have a variable flow oil pump that varies oil pressure as the vehicle RPM varies. The problem comes when the oil is drained out of the pump and the pump cannot re-prime itself.
When performing an oil change, do not drain the oil for more than 10 minutes and get the fresh oil into the engine as soon as possible, otherwise the pump MIGHT completely drain out and not re-prime, leading to it failing to run. Even increasing the engines RPM will fail and most likely cause unnecessary damage.
So ensure that the total drain time is less than 10 minutes!
