According to the linked document from 2008, the average emissions for a passenger car was 0.693 g/mi for NOx. This is an estimated average for gasoline vehicles, arguably close to the fleet average due to the low number of diesel passenger cars on the road.

Hydraulic oil doesn’t evaporate as easily as gas does leading to a much lower concentration of vapors. The metric for this is referred to as the flash point, the temperature at which vapor concentrations are high enough that a spark or other source of ignition will ignite them:

When servicing the cooling system, attach a shop vac (that you don’t care about) to the radiator neck so you can replace fittings below the water line without draining the system. Also applies to hydraulics, but never use with fuel! This works on smaller fittings down to about 1" diameter, but wouldn’t be suitable for…

The Eco (2011, manual) actually squeaked a 36 mpg rating (2011, 1.4t auto) up to 42 meaning the Cruze was “caught up” years ago, but why actually bother looking at numbers when you’re already in that “meh” mindset?

Actually his statement about less un-sprung weight is correct as removing the drums that originally come with those axles and replacing them with a single disc would remove a fair amount of weight. I’m not sure I’d consider it an in-board braking system like some Jaguars where the brake is mounted to the chassis, but…

Looks to me like that ripped off much more than just the ball; I’d say that was the entire ball mount.

Every. Fucking. Time. I get so tired of that crap.

Well, technically that’s not OK, but enforcement is the problem. I guess it’s reasonably easy for them to block a car at port, but not so easy to chase down random vehicles on the road. I think a lot has to do with the fact that a vehicle may pass the local state laws making it difficult for the EPA to identify…

Any failed or failing group buy; particularly when the organizer refuses to throw in the towel and drags it out longer than a year with no to few updates.

Well, I don’t necessarily mean just starting and running. I mean maintaining consistent fuel ratios, emissions, etc. A carburetor could certainly run, but to maintain the same AFR at 0F as it would at 100F required some tweaking. Even then, some carburetors had to be treated gently when cold although I don’t doubt…

True, but it’s difficult to get carburetors to consistently do this, day-to-day and as the seasons change. Direct-injection, however, has a thrown a whole new element into engines that I don’t think carburetors can match. DI engines can run much leaner without mis-firing thanks to concentrating the fuel-air mix in a…

Pretty minor, but I once took my Conquest to a local shop to have the A/C topped up. They determined one of the hoses was leaking and they couldn’t legally recharge it. Apparently, however, they were legally required to recover the remaining freon and charge me $64 to take a car that had working a/c and render it…

Yup, many land speed record cars are actually heavily ballasted. I recall talking to one team with a V8 powered Opel GT and they had in excess of 1000 lbs of ballast to help keep it stable and planted. I want to say they had it at over 5,000 lbs total weight, but this was years ago.

I had an ‘89 with over 200k on it that chirped the belts as you described. I always suspected that the main pulley (on the crank) was worn and needed to be replaced, but never did.

Well, seeing as how she just had a modestly high speed spin out and assuming she doesn’t cut donuts on a periodic occasion... I’m going to say she had a panic moment and lack of clarity. It seems obvious to not drive into the ditch, but she didn’t even bother to stop and collect her thoughts after spinning out. Seems…

Same. I was playing with my Cruze because I didn’t like how touchy the brakes were. The car has a vacuum pump to provide vacuum if the engine is under boost and I was attempting to run the brakes off just the pump with the end goal being to change what pressure the pump cycles at.

Yup, I’m willing to bet the “defeat” they’re talking about is just the thawing cycle. DEF turns into a slush around 12 F and the tanks usually rely on engine coolant to warm and thaw them out, ergo it can take some time before the system becomes active; especially if you try and let the engine idle to warm itself up.

The lawsuit stinks of someone not understanding that the SCR system can not activate until the DEF (diesel exhaust fluid) has thawed. In cold weather the system will be inactive until the DEF tank heater can turn the slush into liquid.

Mmmmno, I’m more of a sedan or wagon fan.

It never ceases to amaze me how people will shit all over a car and the people who buy them just because it doesn’t fit their needs or suit their fancy; as though any opinion contradicting their own is completely asinine.
