Hey all just bought the above vehicle but cant find recommended fuel Octane rating. American website saying 87 is fine but not entirely sure what this means, if we use the same ratings here etc. Anyone know? Cheers

I would be putting high octane in it.

Here, . sift through this chart, your question would be answered with 91 nz octane a splash of toluene will lift your rating . adding extra N and O atoms you can modify the mix to ( trinitrotoluene ) TNT . and that be a real blast

USA uses the (R+M)/2 Octane measurement. NZ uses RON measurement
87 (R+M)/2 = 91.1 RON octane
So putting in regular fuel should be fine.

Std 4.6L = 91

This!
Not sure what the hell you're talking about but it sure sounds good.

Jeese. if you can afford a Mustang, then surely you can afford to put decent gas in it.

Nothing wrong with running 91 RON octane in an engine that was built to run on it.

Ford are tuning the crap out of a crappy engine with higher compression and tolerances etc , What you can't see is the cars computer retarding the spark and doing other stuff to run on NZ's shitty fuel and thats not a good thing. Personally I would run 95 or 98 Octane and whatever you do, don't run blended fuels. Its screws with O2 sensors etc, same with other high octanes which have lead. You can't tell all this because the cars computer doing the hard yards unless you know what you are doing and have the rolling road and test equipment, besides all that, fuel is the cheapest cost of running a car, so buy better fuel.

Thanks all, I'll run the cheapest fuel I can after buying the damn thing lol! Where is the chart tho lada dude? am I blind?

If economy is the issue, I would suggest you actually test both fuels. Most cars I have tested don't cost any less to run on low octane because they don't run as efficiently.

SORRY chaps, why I keep on omitting the good bits, I really don't know why ? I must make the effort to lie on a couch, and have someone examine my thought process . or lack of it
We have that engine, albeit in a different car. Our manual says 95 RON, but that is based on the European market. I personally wouldn't run it on 91.

This - and when you do it, you will find that you get more miles per tank using the higher rate. Then do the sums. After doing this myself, I won't bother using 91.
