91 RON in weestrom?

The dealer told me I should put 95 RON in the weestrom (over here called premium) but I was curious, is this important for fuel injection or anything like that - ie something really important that will screw my bike if I dont follow it... or is this just because its better fuel and will keep the bike running nice?

I ask because sometimes it may not be always possible to get 95 RON fuel and might have to get the standard unleaded - only had to fill it up once so far so was wondering this at the petrol pump

My dealer told me to use premium too. He was just as wrong as your dealer. 91 RON is what it takes, just like it should say in the manual. Here in the States it's 87 (R+M)/2.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s
See https://www.stromtrooper.com/general-...nicknames.html

Read the manual. I think Suzuki has a better idea than the dealer. He probably is too used to recommending the spendy gas to performance bike riders.

05 / 650 in blue
88 / KDX 200 in green
81/82 DT 175 Yamahussies
79/SP 370 Suzuki-bad bike-no keep
78/ GT 750 water pumper
75/Suzuki 125 RV

run it on regular. premium is only required with turbos or very high compression engines.
you'll actually get more power and mileage and less polution out of the regular.

i only ever up the octane when the engine pings, and then i do it by adding a bit o octane booster. no point in spending more $ on gas than needed.

That does not compute. You do NOT get more power by using regular instead of premium.

Also - although regular is called for, some folks use mid grade or premium to prevent engine knocking. (the Strom does not have a knock sensor.)

Low octane burns faster (that's why some engines predetonate) and burn hotter. The whole reason for 'premium' (an oxymoron if there ever was one) is to prevent pinging or predetonation. It is no better, just more expensive. In fact an engine can form carbon deposits from burning higher octane fuel when it is not necessary.

If the engine knocks, up the octane until it goes away, but these bikes should run fine with the mfgr's recommended octane.

Think of it this way; Why do you think that the manufacturer recomends a certain grade of fuel?

Because the engine was designed to operate at peak performance with that particular grade?

Bingo!

The engineers designed the engine to operate with that particular grade of fuel. They give you that information in the owners manual so you won't run the wrong fuel grade in the engine and have problems.

Screw what the Dealer "says". go with the manual.

i wouldnt make such a statement without being able to back it up with the relevant science. not if you're going to try to contradict someone.

so here's the dummed down version of the science:
to prevent pre-ignition, premium gas was made kind of "less combustible" in order to allow high compression engines to burn it when the spark happens as opposed to some random moment when the piston comes up and creates enough pressure in the combustion chamber from compression.
an engine that does not compress sufficiently will not cause the premium gas to burn completely (sometimes leaving carbon deposits), and will not be able to extract all the energy from it due to incomplete combustion. the end result is that you get less power out of the super than from the regular on a low-comp engine, and you pollute more.
so yes, you do get more power by using regular instead of premium.
if you believe the opposite you fell victim to the marketing hype and you're harming your bike, your wallet and the environment.

if an engine designed to run on regular pings, you're either in too high a gear going uphill, or there's soemthing mechanically wrong with the engine (sparkplug insulator design? heat-range?). what you need in that case, is to fix the problem, not to up the octane.
(it could also be that running super in it caused hotspots in the combustion chamber due to carbon deposits. running a fine water mist through the intake can clean that up (DO NOT ATTEMPT THIS UNLESS YOU KNOW EXACTLY WHAT YOU'RE DOING. water expands a lot when it hits the hot cylinder and you can blow an engine real fast by using too much)

please note that a little bit of pinging once in a while under heavy load is NOT harmful to the engine, but you should downshift. continued pinging is harmful and should be addressed.

Little bike unknown big bike depending on outside temp you need 89 octane most of the time.
