#11. 206 km ride.
Today a fuel testing ride.
Shell gas stations in Sweden were overtaken by St1 2010 but continued as Shell and their fuel V-Power.
I noticed a few weeks ago that one of my frequent Shell stations got the St1 signs.
The receipt after refueling was St1 98 ron. No more V-Power.
My local Shell station has still the Shell graphics and V-Power on the pump which is not correct.
That fuel cause pinging inside my Blue K6 engine as I proved to be a fuel issue yesterday.
I have read about Circle K and their Miles + 98.
That gas station chain was earlier Statoil which was my regular station before Shell. Statoil gas stations were before that ESSO.
I remember late 60's and the vinyl stickers I could get when I followed my dad to the gas station.
I loved the smell of the fresh vinyl stickers.
The Esso tiger one of the better.
Anyway., I rode my blue K6 100 km away (north) to Hedemora to refuel at Circle K today.
Hedemora was known for TT racing many decades ago.
I got the tank reserve on ca 20km before the gas station. Refilled with 13.63 L so about 3.4L crap fuel left.
I adjusted the ignition , advanced it almost as it was before.
Filled up with their Miles + 98 fuel. (98 RON).
I was easy on the throttle in the beginning to get the crap St1 98 less power- more pinging fuel out of the carb bowls.
Bike got its torque back!

No problem to cruise in 5:th gear and slowly reach 140kmh where I whacked the throttle wide open. No pinging around 7000rpm!

Good grunt from before 4000 rpm.
Circle K Miles+ 98 is approved by my blue K6.
I bet my car will love it too.
Shell V-Power is no longer here in Sweden. R.I.P.
St1 98 RON is more like a lower octane fuel like 95 RON with less ethanol, E5.
My rides will be a little different, other gas stations. Circle K has more stations than Shell/St1.
Here photos of todays ride with a happy ending.
Food at home, grilled chicken wirh spicy rice and a tasty spanish red wine
Good Brie cheese and blue mold cheese with crackers.
I look forward for more rides and refill again after reserve has kicked in to get more of the crap fuel out from the system.
It is not good for the engine.




EDIT:
I have searched for the crappy St1 98 fuel and found results that support my findings I learned the hard way this spring.
Car tuners with dyno and users:
- St1 with last versions of V-Power 98 RON delivered in Sweden the worst fuel/lowest quality.
- OKQ8 has the best 98 RON fuel.
- Circle K comes next. (Ingo 98 same)
- Preem 98 works too. Plus others.
So last dyno late October 2022 could have been better with OKQ8 fuel

Maybe the 110whp goal might have happened then?

The rich area before 6500-7000rpm is sorted after this run. (Better needles(taper), cleaned carbs, smaller pilots and less acc pump stroke)

Funny, gas station OK with their 98RON fuel made my K6 with 836cc to ping at 120-130kmh (around 5000rpm) when twisting the throttle from 100kmh ca 4000rpm) in 5th gear . 17:48 sprockets as today.
Esso 98 not. It was better back then 1984-
