I have a 2000 GMC Jimmy 2WD with 140k miles on it but now only drive 3-4k/yr so I really don’t want to replace it or dump $$ into it. Last year I passed the smog test but was close on the hydrocarbon limit (I did nothing before the test). Here’s what I’m considering…
New air filter
Use either Run Blue Sky Clean Air or Prestone Emissions Reducer
Oil was changed <500 miles ago
Use premium gas in a <1/2 full tank
Check tire inflation, gas cap is on completely
Go to the test with a hot engine (keep it warm while in line)
I do understand the purpose of the smog test…but have to weight the cost (and environmental impact) of a new car vs using the existing 3k/year… I’d possibly a different outlook if I were driving 20k/yr.
Any suggestions on the test?
