i actually serviced the car myself, i used full syn oil, i used pretty good oil as well, i cant rem what it was but i work in the tyre trade and a supplier sold me it, i think it was 5/40 plus i flushed the engine as well, changed all the fllters uncluding the fuel filter, i also used dipetane for a while as well, it did help the smoke a bit. i got a mechanic to check the mounts as well, he said they were all solid plus he said the car pulls really well because it took it for a drive. The smoke cant be seen alot during the day but i can just seen it come over my back window a bit, its really bad at night
