I see on some threads people are using different octane gas.I have always used premium,but wouldn't mind saving some dough.It didn't used to be much difference cost wise,but now I see regular for around 2.60 a gal.,and premium well over 3.00.Will it hurt the bike? Is the mid grade better? I've paid as much as 4.99 for premium a while back,so I'm pretty happy it's less than 3.50 now.But 2.60 is tempting.
I have a friend (cheapskate) who always tells me I'm "wasting" money by buying premium.
Owners manual for both '02 Sportster and '07 Ultra tell me to use premium.
Depending on the station, sometimes I can't get premium and had to settle for either 87 or 89 octane.
Never could tell any difference but I still go for premium anyway.
Happens to be a few stations here that have single hose premium (no alcohol) gas so we try to get gas at those stations.
We also comment to the cashier how we appreciate the singe hose and why we fill up there.
Your .40 difference a gallon wouldn't bother me. You can only put so much in the tank. Not going to ring up a huge difference.
If I took a trip to the coast (2,000 miles) and if I got 40 MPG, I'd use about 50 gallons of gas.
50 gallons X .40 extra a gallon for premium is only going to add $20.00 to the gas bill for the trip.
(You'll pay more for your Starbucks cup of coffee on the trip.)
I like my engine to be happy so I run premium.
Plus I like the extra power from premium in the mountains.
