Went to Concourse with my 2002 Toyota Siena. Its engine light was on, catalytic issue, oil had run low ( pretty sure I was at fault - changed my own oil and drove way too long between changes) causing more diagnostic issues. Manager at Concourse had a tech look at the car, Manager said, The car was burning oil, your engine is toast, etc Knowing my car - it does not burn oil, I tried to suggest ithis and ask if there was a different approach to try and repair other than rebuild the engine. He told me that I obviously didn''t believe anything he was telling me, then saying "I don't argue with customers, here are your keys, we are done- leave" . I stood in the parking stunned for a few min, googled Oil Change, went north 1 mile Kwik Car Oil, they changed my oil, suggested a new spark plug sensor to fix the rough ride and in fact it fixed the catalytic issues as well. Darn right I didn't believe what Concourse was telling me.
Marty, we have been in business for over 30 years and have a policy not to waste a customers money on repairs that will not fix their car. We checked your codes in the parking lot & started discussing if any repairs would make sense on a 150k mile vehicle, with the possibility of internal engine wear, causing a need for very expensive repairs... The oiling system on your engine is a closed system and should not require the addition of large amounts of oil in between oil changes. Oil is not used in the process of lubrication; it is continuously recycled and should remain at the proper level until it is time to change it for maintenance. You stated you had run your engine low on oil and it was not leaking out on the ground. The only other way oil leaves the engine is internally, which in the process exits through the exhaust. This is a result of engine wear and there is no quick fix. The catalytic converter & spark plugs cannot survive the continuous contamination with engine oil, and soon sets a diagnostic trouble code for their inability to perform as designed, which your vehicle had along with numerous other codes. There is no spark plug sensor on your vehicle. I suspect the oil change place sold you an "oxygen sensor", and/or spark plugs, cleared your codes. Very shortly, your vehicle will retest the catalytic converter and reset the code and turn the light back on.(Which will not pass inspection in Tarrant County) I suspect the oil change place may get a bad review at this point for taking your money.
