beetle developed a flat spot when fueled with 98?
I drove about 550klm today in a very noisy baja.I was almost empty and i put half a tank of 98 bp fuel in her and by the next set of traffic lights
she had developed a flat spot where you had to feather the throttle to try to drive out of it.
On the way home i again almost empty filled her up with the cheapest unleaded and again almost immediatly the hesatation/flat spot was gone? Any
ideas?

98 doesn't evaporate as quick, and burns slower - hence the flat spot. No problem in a knock-sensed car, no good in a carby-fed low-comp donk like a
VW!

As long as it's tuned for higher octane it's no problem to run 98. Timing is critical as others have mentioned.
A POSSE AD ESSE.
I live in my own little world, but it's okay, they know me here.
