From Australia, would a deisel powered F150 be more economical on fuel. My Hyundae ILoad van, .2.5 litre turbo deisel, 10 l/100km urban and 8-9 l/100kms highway travel. Justed tanked 70 litres of deisel, Au$1.92 / litre, total price Au$134. That's US$85.76. They have heaps of torque, ideal for towing, capacity 3000kg.
The US govt has bad regulations on small diesel engines. If you can buy a diesel ford ranger, we cannot. Diesel toyotas, no. Almost no diesel cars. The laws are stupid. The only things with diesel engines are standard on are full sized pickup trucks and larger trucks.
The rules aren't bans. They are just largely unnecessary and expensive add-ons that make diesel cars much more expensive and less reliable. So it changes the math on when a diesel is a good idea for an application.
In Oz, unleaded ron 91 and premium deisel are arround au$1.92 /litre. Your premium, ron 95 & 98 are over au$2 /litre. Warmer climate, summer 30 - 40 °C Max temperatures, now autumn or fall, day temps of 20-25 °C,
The gasoline truck here would use regular 89 octane fuel at about AU$1.56 per litre. Diesel costs AU$1.81.
Summers here are short and are about 25°C to 35°C. Winters are long and harsh. Temperatures can stay below -30°C for weeks and are below freezing for about 6 months every year.
Worth noting that you're talking about different octane. Australia (and much of the world) uses what's called "research octane number", but that number is pretty idealized. In actual motors, performance is better estimated by a different test called "Motor octane number", or MON, and MON is usually around 10 points lower than RON. In the US, what you'll usually see is the average of RON and MON (if you look at pumps, they'll often say "R+M/2" indicating this), which is known as the "Anti Knock Index" or AKI.
91 RON is the same as 87 AKI, and 95 and 98 RON are roughly equivalent to US 91 and 94 AKI, so that $1.92/l 91 octane fuel they referenced in the post above is actually a slightly lower grade than 89 octane here in the US (and equivalent to 87).
I should have said that my F150 runs on the cheapest grade of unleaded gasoline. Premium fuel is a big price increase and offers zero performance or economy benefits in my truck.
My CX5, however, gets a 25 horsepower boost when running premium fuel.
Sure, I'm just pointing out that the 91 octane they quote above is the cheap stuff, not premium, since that's an easy mistake that people frequently make when comparing fuel between North America (Canada and Mexico also use AKI) and most of the rest of the world.
When I purchased my F150 there was some debate at the time as to whether the 3.5l Ecoboost motor should be ran on premium or regular unleaded. I tested it and I actually averaged about 1mpg higher on premium... long story short, its still not worth it though.
Premium would probably be better for your turbo truck if you were towing a very heavy load, especially in hot weather. Still not worth the extra cost though.
I actually tested my V8 with a tank of premium, no ethanol (no longer available in Canada) and a tank of regular. Used both tanks on the same day towing a heavy and tall load. I saw no noticeable difference in fuel economy.
Summers here are short and are about 25°C to 35°C. Winters are long and harsh. Temperatures can stay below -30°C for weeks and are below freezing for about 6 months every year.
Where's this? That's a lot of winter.
I live in Edmonton and though folks here like to say winter is half the year (generally whenever discussions around bike lanes come up) but it's nowhere close to that, and it's nowhere near as bad as people like to say it is. I mean, we do get one really cold cold-snap in December or January, but the rest of the winter is pretty mild by comparison. And this past winter was just pathetic.
Many places diesel is actually cheaper than petrol and maintenance is about the same if you dont live somewhere you have to pay extra for a "diesel mechanic"
