Mazda BT-50 Engine Problems

The official fuel consumption (average) is 10L/100km, which is a guide to what you should get, but it will vary depending on the driving conditions, load carried etc. Yours isn't wildly out, and given that it's new and running in you could expect it to improve as it does more kilometres. I would suggest you report your concerns to the dealer and maintain a log on the consumption you get with the view of presenting it to them at the next service. If it hasn't improved by then you should have plenty of evidence to justify your claim that something is not right.

Just above the exhaust manifold.

Your engine will not fail if you use the correct specification of oil, even if it's not synthetic, but Mazda spokesman Tony Mee has the company line: "The specification does not indicate that the oil must be a 'synthetic' product, however . . . the Mazda recommended engine oil for BT-50 is a high quality 'synthetic' product that supports long-term engine durability and performance. The service schedule has been developed to ensure the long term durability and performance of the vehicle including all systems".

Thanks for the tip. We'll add that to our list of things to look out for on the Ranger. Presumably it's the same with the Mazda BT-50.

It's most likely an intermittent fault with a sensor. By restarting the engine you are rebooting the computer, which is a sign of a fault in the engine management system.

You shouldn’t need to be draining water out of the system every couple of weeks; that says there is something wrong. Your mechanic is right; the dealer should have flushed the fuel system out to make sure there was no water in the system when you drove the car away. I would go back to the dealer and talk to him about some sort of compensation. They haven’t been as diligent as they should have been.

It's too early for a reliability read on classy utes such as the Ford Ranger/Mazda BT50 and VW Amarok, which with their lusty turbo diesels are great for heavy work.

Glad you're going to wet the tinnie. Ford after-sales people Stephen Kruk and Linda Minardo helped speed things up. And if you need advice on BT-50 crank angle sensors, Pete's your man.

The claimed fuel consumption for urban driving, which would seem to be what you are doing is 11.8 L/100 km. On that basis your consumption would seem to be too high, but your car is still very new and I would be giving it more time to settle in. You could go for a run out on the highway and see what that produces.

It's a diesel, so it's not pinging. I suspect it's the injectors rattling. Have a diesel mechanic check them for you.
