hi, i read you post about how to make your care run better to make it ready for the required state emissions inspection. i live in california at its call the "smog check" and i was wondering if there are tip or tricks or if there is a way to cheat on your emissions inspection to make your car pass so it doesn't fail. i've heard that there are places where they will pass you even if you have a bad car. anyway, if anyways can help me with this it would be great, i have taken my car to the shop to have it test it but it keeps failing the smog check and i don't know what to do anymore. i don't want to get rid of the car because i love this car, imy grandfather gave it to me and it has sentimental value.
UPDATE: just wanted to let you know that i was able to get my car to pass the smog check. cheating is not the way to do this. you are just going to spend more money and you are going to fail. i know its frustrating when you car fails the emissions, but just remember that these requirements are there so we can all breath healthy air. my advice is to just repair whatever is making you fail the emissions test. you will save money on the long run. you have to be careful adding chemicals to your engine because it will break your engine and you are going to end up spending more money than you though. a new engine will cost you like $5000 dollars.

hello, i work at an inspection place... and basically what you need is to have a tune up, have the cad, and have the regular maintains . for vehicle 1996 and up, if it has the "check engine" light on its a red flag automatically fails. oh for the 1985 truck(tony) that only requires a "safety sticker". if you have anymore questions i will be glad to help.. e-mail: p.jautosalesinc at google

the best thing to do in your case is apply for an exemption. just go to the DMV and tell them your car is a classic car.
or if you are having problems, the government will give you $500 credit to fix your car.
anywayz, the best thing to do is not cheat and be honest about it

Re:How much alcohol to add..
In the test referred to above,
various fuel mixtures (0%, 15%, 25%, and 35%) of Ethanol and gasoline were tested by a certified technician using a gas emission analyzer. The test was run for High and Low RPM conditions.
It was found that levels for all pollutants measured (HC, NO, CO, and CO2) decreased as the
concentrati of Ethanol in the fuel increased, for both RPM levels.
Note that 2 to 10% ethanol is typically being added to the gas before you buy it at the pump anyways (depends which brand you use), so generally speaking, adding a bit more can't hurt. Add it when the tank level is low.
Gas up after the test since too high a mix ratio washes the oil off cylinder walls and prolonged use causes premature engine wear!
Note that Ethanol means 100% ethyl alcohol. The kind you drink. You can only buy it "Denatured" which means that other stuff has been added to make it undrinkable and/or taste bad. Anything less contains water and can't be used.
Methanol (wood alcohol) and Isopropanol (Rubbing alcohol) are cheap and easily found at 99% purity and they might actually work too, but the test referred to was conducted with (Denatured) Ethanol.
