Thanks for the help. I changed plugs and air filter, took it for
emission at Econo Lube on University and Regina.. It FAILED at HC 81.
Then the guy changed oil and put in thick synthatic oil (PZ26)
instead of regular oil and did retest. It just PASSED at HC 52.
Allowable limit is 52. At least I dont have to worry for 2 more years.
Just for information, I have learnt that synthatic oil burns much less
than regular oil, so HC is reduced. It cost $50.00 more, but saves the
other hassels of adjustments.
