What octane is best for Aussie Roadster

[Rick McC.]

I was in shock when I read 8mpg but then I remembered the US gallon is 3.784 litres our Imperial gallon is 4.546 litres about 33% larger, my 1979 460 powered F100 Custom long wheel base gulps lpg at 33 litres per 100klm or 8 miles per imperial gallon, slightly better 12mpg on petrol ouch! but she sure rattles some windows and eats Nissan Navara's for breakfast and goes looking for a Toyota High Lux for dessert lol

just like the rockets ,no replacement for displacement,

If memory serves; Torchie's SRT10 puts out 505 HP from the factory.

When I hauled the 30' snowmobile trailer with two sleds and some extra stuff to Quebec and back I averaged 8.8 mpg with most miles in 4WD. Without the trailer I am getting 16.5 mpg with my new 5.7 Tundra SR5. Should inch up a bit in another 1,000 or so of break in....I hope.

When fueling up my sled in Quebec I noticed that Shell premium had NO ethanol. Wish that were the case in the US. I burn premium in my ski doo.

Down here, most anyplace on the water (Gulf of Mexico) will be selling "boat fuel;" which will usually be a mid-grade ethanol free gasoline.

Just one of the many perc's of waterfront living.

My R3R has never had any ethanol in it since my first fill-up.

Us Aussies are blessed in more ways than one ,but one of the blessings is the only Ethanol mix (10%max) is the low octane mostly 91/92Ron, our 95 and 98 and occasional 100Ron are Ethanol free and readily available at an inflated cost ,our LPG is 100% octane but recently has increased to 2/3 the price of petrol, 91Ron is the lowest available locally ,therefor Diesel cars and Suv's are getting increasingly popular ,I also have never used an Ethanol fuel in any vehicle,
