I always pump SHELL after get the new car. This tank try the SPC, burn 3/4 tank only travel 300KM, but with SHELL at same level, I can get 400KM. Can the SPC so bad? :crycry:or the car's computer system need time to know SPC pertol?
Travel pattern is almost same, and tire just checked 2 weeks ago. Anybody experienced this before?
