My car with a normal driver
Well my business partner borrowed the saturn to view a property out of state. I thought this would be a good time to see how the saturn would do with a "normal" driver.
Tanks are as follows 456.5 10.2 44.75mpg (EGR disabled) 395 9.33 42.33mpg (The EGR valve was enabled at 5/8ths tank) 237 5.87 40.37mpg average 42.85mpg. Its interesting to not that the average cruise speed, on interstate, was 79mph or above. He shifts late 3k rpms+. He stated that he ran the car hard the last tank. He also said that he ran the car very hard for 1.5hours on country roads late for an appointment. I was experimenting with the EGR before he left. So I let him run a tank and then had him plug it back up. I will be testing this further. |
interesting...how much better are the emissions with it working?

egr's are crap...lol both are disabled/ broke on my cars and cost 60-$100 to repalce. screw that

I thought a correctly working EGR valve will give you better mileage?
I cleaned out my EGR valve and passageway at the intake for smog testing (failed NOx). I noticed better mileage, but that could be due to several factors since I did alot of work getting my car back together (new tranny bearings, new plugs, air filter, tranny fluid, colder plugs, etc). I might just plug my egr intake port just to see if I get an overall increase or decrease in FE. Gary |

Better than FE is reduction in NOx emissions etc. ;) |
What is a egr?

So basically if one were to unplug the electrical connector, FE would go down because EG would be R-ing all the time.
