i just use normal oil from my local motor factor (to citreons hand books spec), i have 93000 miles on the clock and its never missed a beat and she slighty modded. Ive had her since she had 35000 mine on the clock and my bro did the serives on her after the warranty ran out because the car belonged to his mate. i work on the theary(sp)avarage quality oil and 3000 miles changes. but every ones differnet.
