u brought up a good point there. saving $100 a year is a good enough reason for me to keep running 91 octane. i mean i can save more than that if i quit smoking :lol:Randoramma said:Premium gas costs 15 to 20 cents per gallon more than regular. That can add up to $100 or more a year in extra costs."
Mine says use at least 87 octane. I use 89, my car runs best with it.DragonRM said:anyone else's rs car manual ask for 91 octane? Mine does... I use it anyways but I've talked to a couple other people's who don't.
Yeah, I think it is universal. I could be wrong though. I think most Americans don't know what the Research Octane Number is so we never say, "89 RON" or "91 RON" we just call it "91 octane." But I think we're talking about the same thing.25* General Zap Brannigan said:i didnt know american grading was so low? RON rating is universal right?
Ok, let's see if I can do this right.25* General Zap Brannigan said:to give you some idea on price normal petrol is 95ron and 80-90 pence a litre (=$1.30) and for 98ron can be as much as £1 per litre! Thats $1.50 per litre and $7 per UK gallon! My car does on average 19 miles to the gallon
:stupid: WOW déjà vu! Looks like I did this already, way back on page 4!!! :lol:. Looks like AU gas prices are comparable to those in the UK.rsowell28 said:That's better than what I pay out here in Southern California.
$1 (US) = $1.92 (AU)
1 gallon (US) = about 3.79 liters.
So you pay $3.79 (AU) for 1 gallon (US) of gas.
$3.79 (AU) = about $1.98 (US)
I pay about $2.10 - $2.20 for 87 octane while people in Australia get away with $1.98 for 98 octane! Damn...
I guess Australia has better gas prices than California!
(Unless my numbers are wrong, which the very well could be, in which case, please disregard everything I just wrote and pretend I never posted any of this).
Yeah, I prolly should have mentioned that. CA has their own gas that's different from the rest of the country.DragonRM said:prices in CA are higher than everywhere else too... in CO I pay about $1.90-$2 per gallon for 91... It has its ups and downs but that's about average. When I first moved here a year ago it was $1.70 for 91
