Has anyone found when using Tesco fuel lately a slight misfire and holding back??

 

Always run mine on the tesco 99 stuff good as gold it might be down to the hot weather that we have at the moment. Turbo car's just don't like it.

 

mine was the reverse i had a my95wrx 260 and it hated tescos stuff threw my knock sensor and made my car slow and held back , ecu reset and v power it went back to normal .hot weather wont help either as said above.

 

mine too knock sensor went loopy and general running temp of car was high, no probs with V-Power

 

My knock is fine only late teens on the fc commander. old engine was fine on it . New 2.5 and now on high boost it seems to hold back put v-power and after couple of days it slowly sorted it self out . Thought it was down to something else so put tesco back and within 3-5 miles back it came! filled her up to the brim with v-power and again slowly she coming back . hoope it's just down to poor quality fuel at the mo!!!

 

One of the Tesco stations near me (petrol and corner shop type) has suddenly turned to an Esso station. Must say though I have had no running problems with Tesco 99 at all. Can't get a hold of V-power very easily as no Shell garages around me.

 

Never had any probs with 99 from Tescos, other than sourcing it in other areas
