Like I said, a noob question... How important is 91 oct. fuel, how bad is 87 for a ST165? Sorry, thanks...
toayoztan":1cj0umiy said:Also, look at it this way:
the difference between 91 and 87 octane is usually around 20 cents
20 cents on a complete full tank of 18 gallons saves you $3.60
let's say gas is 2.50 per gallon, that means 3.60 will give you 1.44 extra gallons.
1.44 extra gallons let's say at 20mpg on the alltrac gives you 28.8 miles
So...do you reallly want to risk your engine for an extra 30 miles? To some, that lasts an extra couple days, to others that isn't much at all (it's all relative).
Or, you can look at it more general. From the math given above, you gain an extra 1.6 miles for every gallon you purchase of 87 vs 91. That isn't much in the short run.
I wouldn't risk it for 30 miles :wink:

also, at gary: what's QFT?
quite fricken true? :lol:
honestly...gas mileage isnt TOO bad unless youre comparing a big block chevy engine to a civic.
anything AROUND 20mpg to me is pretty good. maybe not if you commute long distances, but in that case...get a civic!

Do you not let your gas tank run close to E, and then fill up a full tank? Just curious, because some people don't let it get that near empty.

Yes, if not more. I have gone 55 miles with the gas light on constantly.
