Re: Hybrid Tahoe Fails emission testing
Most state mandated "emissions" testing is a complete joke. Unless they strap the vehicle to a Chassis Rolls Dynamo meter and attach a real emissions bench to the tail-pipe, there is no better way to measure if the systems are working.
That's at least $500k worth of equipment or much more and an hour and a half per test with another half hour of post test analysis. Not likely.
One could probably set up a little programmable box that contains the VIN and will return a NO Codes message in CAN script to the so-called tester. Hide the real data connector up above. Cut an old one out of a junker.
It wouldn't be very hard for the Scan Gage kind of guys to do.

The GF-5 rating is the ILSAC-International lubrication standardization and approval comittee rating, this rating can (and does) apply to most modern oils including mineral(dino) oils. it has nothing to do with the base stock or being synthetic.
The API-American Petroleum Institute base stock group rating is what determines if an oil is synthetic or not.(this is the crux of the controversy)
They wisely do not disclose this. This is why it's very easy for them to manipulate the facts to an unsuspecting consumer.

scroll down to "Standards" on the wikipedia page and prepare to be bored to death.
