2007 Expy EL fuel advice
I've just bought a 2007 Expedition EL with delivery miles on the clock (a long story, but basically it's been standing for 3 years and I got a risky bargain).
Here in Saudi Arabia we have the choice of two fuels (which I presume are both unleaded but no-one here seems to know) - '91' and '95'. I also presume these are the octane levels, but again no-one seems to know for sure. I always put 95 in my old car (GMC Envoy 2004) because my knowledge of fuel extends to the maxim "put in the best you can afford". Over here, 91 is 0.45 USD per gallon and 95 is 0.60 USD a gallon, so 95 is a no-brainer if it 'improves performance and fuel economy'.
So, are these numbers likely to be octane levels, and if so does this mean I should be putting in 91 fuel rather than 95? Of course, the manual says you shouldn't put in more than 87. Or is the gas here likely to be substandard quality so I'm safer with 95?
I hope someone can help with my confusion! I'd love to save a few bob by putting in the cheapo stuff but somehow it just doesn't seem right with that gorgeous engine.
PS. This is my first Ford truck and I'm loving it...
