Her only complaint is "the car doesn't go up hills." haha
I put Castrol Magnatec 10w-40 in it, just because this oil claims "better start up protection" more than anything else. Seeing it's just her daily commuter car, i thought this was justified...
Might try some "stop smoke"... usually i don't, because usually little things in bottles are just a wank ( i believe in good maintainence, good fuel and good oil). But because this isn't my car, i might just shove some in and see what happens.
