They have put 20 W 40 oil instead of 20 W 50 oil.How will it affect the engine? do i need to change the oil to 20 W 50 immediately?
As they say, is it really the problem with the valve for the slow speed problem? I'm seriously pissed with their service.. Gurus, please answer my queries.


... is your going ok now? was it really engine oil issue?
