Fuel Types for Oz Prius

Hmmm, maybe. I've used 98 in other cars before and it can make a difference in some and none in others.

I have put 98 in my Prius before and it appears to run smoother but no mpg difference.

 

Hi all,

Another Australian Prius here - was wondering if we could use standard E10 fuel here in NSW and the possible detriment vs using 95 or 98 as recommend in the manual? Read the thread already, but was wondering if anyone else has useful tips.

Thanks in advance

Edit: Just noticed I posted in the Gen 3 thread when mine is a Gen 2... oops

 

Assuming that the numbers in the manual are for the octane measuring system where you live,
you need to use the minimum octane listed. The presence or absence of ethanol has no bearing as long as the number is right.
There is NO advantage to using a higher octane than you need.

There is a slight loss of energy with E10; about 4% so getting non-ethanol fuel would have a mileage advantage......but only if it costs less than 4% more.
