Alright my peeps, this is a short story on my Suzuki DR650, and it's oil. Oil brands are "A" "B" and "C".
Factory fill on the 2017 bike was unknown, and changed at the 600 mile break-in service.
Oil "A" was added at 600 miles by the dealer until 2000 miles. All oil mentioned here was 10W40 motorcycle oil.
I used the bike to commute to work 120 miles roundtrip on the exact same route, using the exact same gas at the exact same pump.
After 11 trips, this was the average miles to reserve and average mpg
Average miles to reserve: 112
Average mpg: 44.9 mpg
At 2000 miles I drained and changed the oil to brand "B". I took six roundtrip commutes using the same route. To me, the bike felt like it was breaking in again, shifting was notchy and the bike just didn't seem happy. Below is the mpg for each trip and best and worst miles to reserve:
Lowest miles to reserve: 99.7
Highest miles to reserve: 107.1
MPG:
Trip 1 = 41.9
Trip 2 = 42.4
Trip 3 = 42.6
Trip 4 = 42.1
Trip 5 = 42.8
Trip 6 = 43.1
Avg= 42.5
Not happy, I drained and switched to Brand "C" at 2750 miles.
I noticed right away the bike shifted smoother within a few miles and seemed to rev freely again. After one 120 mil round trip, check this out:
Miles to reserve: 117.1
MPG = 46.75
Folks, that is a 10% increase in MPG in just the first trip, that can not be a coincidence. I'm a believer!
Brand A = Suzuki EcStar
Brand B = Honda GN4
Brand C = Amsoil Metric 10W/40
I am not an Amsoil salesman nor do I have any financial stake in the company.
But...Amsoil did a study on 32 motorcycle oils and in the 40 weight class oil Honda's GN4 finished 12th out of 15 oils!
All I know, on my CBs I will run the Honda oil until 2000 miles and then I am switching to Amsoil. Honda makes great bikes, but for me, their oil did not work well at all in my DR650! Not even as good as the Suzuki OEM oil..
