On one of the shows last night...Current affair ?...Today Tonight ?...they did a comparison between E10, 91 Octane/98 Octane and Diesel...

Found it.....
Petrol that saves you money


A bit of a shock!!!!....apart from the obvious being Diesel was cheapest per kilometer.....the 98 Octane actually worked out cheaper per kilometer than the two other fuels !!!
Yes the 98 octane was the dearest per litre, but it made way better kilometers to the litre, and actually worked out it was cheaper to run the car on 98 !!

I wouldn't have believed it....am I missing something ?

The cost for me is now about the same each week to run ULP or E10.
But I dropped E10 as soon as the price jumped (my own personal protest).
I'm guessing I wasn't the only one.

My other person protest is to never use one of these "save 4 cents" dockets.
Maybe if everyone joined me they would go the same way as E10 and we could just by our groceries and petrol at a non-inflated price.

I Know...I'm dreaming. But I do feel a little better now that I've vented.
I'm with you, I also don't use those "4 cent" dockets... It can take up to 15-20mins to refuel at a Shell at the close of the week's cost cycle due to the que. While filling up at the BP or Mobil up the road takes 5mins.

I figure, the most I could save is a couple of bucks, so I'd have to be getting paid less than $8 an hour for it to be worth my while.

My wife has been filling the sh*t box exclusively with 98-octane and been telling me this anecdotally for years, so I'm not surprised.
There is a few Shell stations that do have 100-octane where we travel. We try to fill up at those. They call it "Optimax Extreme" or similar. However, if I understand it correctly that also has 5% or so ethanol blend*.

Both our daily drivers are Diesels. I've been a diesel convert for about 4 or 5 years now. My Land Rover used to get 800-900Ks out of a tank depending on round town or open road. That works out to be about 11L/100 for a big heavy 4x4. The surprise was how good the economy was with a trailer on the back. with a tandem trailer and Cobra on back I was still getting 600KM out of a tank. My wife's car gets 1000Ks out of a tank or more on a long trip and regularly does less than 5L/100.

The Land Rover replacement is another Diesel and it gets 10L/100 driving to and from work and 9L/100 on a trip. It's got way more power than the old Discovery and is smooth and quiet and still has a 3.5 ton towing capacity. You would be hard pressed to know it was a diesel except for the puff of diesel smoke when you start it up.

One of the nice things about diesels is that there isn't as big a difference between city and highway fuel consumption. So if the manufacturer quotes a specific fuel consumption you are probably going to get close to it in a Diesel most of the time where as a petrol car will be much more dependent on how you drive it. With Petrol getting the manufacturer quoted figures may be a case of all the factors being right i.e road conditions, speed, traffic and alignment of the stars etc.

Diesels take some getting used to living with one but after a while you get used to the turbo lag and adapt your driving to it. They make power differently to a petrol engine but these days diesel doesn't = slow any more. My wife's Jetta had way more perceived get up and go than the petrol version when driven back to back. It just makes so much torque which is what you are using getting off the mark and driving round town. I've found the traction control regularly kicks in on her car.

Cheers
