Iv had my xsara TD 1.9 for 7 months and been very happy with it but now an MOT is due it seems everything has gone wrong all at the same time,but my biggest worrie is the performance of the car in the last week. I was really low on oil and a family member helped to check oil levels and topped up the oil with im sure bog standard crappy cheap oil,he said it would do until an oil change in a few weeks time,seeing as i wanted a lot done before MOT time. The car seemed to be running a bit smoother and quieter after the oil change but as of last week the car has been running really slow,taking much longer to get out of 1st gear and 2nd gear slower also, and it seems 2nd or 3rd is about as far as i can go. when this started happening it would come and go then get worse and worse,now that its going in for MOT tommorow,should i be prepaired to scrap my xsara as i may have done permanant damage with the oil topup. it give an idea,the car now runs max speed of 33mph at a push. i forgot to mention ,the ecell pedal was always a bit stiff to push but since this problem there is very little foot control now ,as the pedal is stiffer and the distance to push it to the floor is shorter. =================================================== the pedal releases fully once pressed to the floor,its manual gears ,the pedal was always stuff,but now seems shorter to the floor,i havent been driving long and know little about cars,im not sure about the throttle cable,tho it has been checked a few weeks ago when the oil top up was done and i was told tho the pedal is stiff the cable was fine. thanks ======================================================= thanks
