1993 Honda Accord EX Wagon Worried Passing Smog Test

My car has not been driven in about two years. In preparation for a STAR certified smog test, I had an oil change, a comprehensive safety inspection; and replaced the battery, because it could no longer hold a charge.

The gas tank is 3/4 full of 2-year-old fuel; on which only ~25 miles have been driven. Surprisingly, the car runs well on this old gas, which still smells fresh (and not at all stale).

Do you have specific recommendations to maximize chances of passing? I read on "smogtips" that freeway driving just before the inspection would be a good idea. For how long, and at what speed would be optimal?

Do you advise a fuel system additive? I've heard they take ~2 weeks of driving to break in. Honestly, I'd rather not delay my smog test.

Using results from the Smogtips locator to receive promotional pricing, I've called every STAR compliant listing. Because my car is pre-1996 and not OBD-II compatible, I expect to pay the coupon price, plus $10 or $15 extra for the tailpipe test. But most shops have been flat-out unwilling to test my car.

When I call, I'm rudely told that they don't do cars that old; or that their equipment is broken. Only one test station was willing to smog my car, and they quoted me a ridiculously high price ($175-$200) and outright refused to extend me any promotional discount.

The coupon prices in my area are in the range $25-$30 (+$8.25 certificate). I feel taken advantage of. Why can't I be offered the same base price; plus $10 or $15 extra for the tailpipe test? Do you know of any shops that would treat me fairly by honoring their promotion?

Thank you kindly for your time.


Answer:

We recommend using up the gas you have in the tank and take the smog test with fresh fuel. Since your Honda Accord wagon will be administered the tailpipe test as well as the visual and functional tests, it'll be best to make sure your Honda's properly warmed up before the inspection. Driving in city or highway traffic for at least 20 minutes should be enough; and it's ok if your car sits for 5-10 minutes while shut off after you get to the smog station. The smog technician will ensure it is at normal operating temperature before the test. Fuel additives won't be doing you much good for the purpose of helping pass the test. Additives are effective over long term use. So for now, we'd recommend ensuring the car's properly warmed up, the check engine light is not on, and the engine is running fine and taking the test.

As for pricing... it is true, since the implementation of the 2000 & newer vehicle tailpipe exemption, smog station's have needed to offset the high cost of maintaining the equipment required to test older cars; as opposed to newer vehicles, which required a much less expensive test equipment. As such there is usually a significant fee(s) added when inspecting these vehicles. It's really the pre-96 years which require an EVAP test along with the dyno (tailpipe) test that drives up the cost.
