Replying to: Mr_Shiftright (Jul 13, 2007 6:58 am) Hmmm, thinking back to the 1970s (when I turned a wrench to make a living), I don't remember tweaking the timing to help cars deal with altitude, that said, I do remember rejetting any number of carburetors.

Replying to: shipo (Jul 13, 2007 7:31 am) Well the bump in timing was great for cars that were going up 5,000 feet for a few days--you wouldn't want to re-jet just for that. Replies to this message: shipo (Jul 13, 2007 9:07 pm) Mr_Shiftright (Jul 14, 2007 6:23 am)

Replying to: Mr_Shiftright (Jul 13, 2007 4:14 pm) Ahhh, got it. If one of the cars I worked on in San Diego was only heading up to the 5,000 foot mark for a few days, I wouldn't bother touching the car, however, the bump in timing doesn't sound like such a bad idea. The only cars I rejetted were the ones that were heading up into the Rockies or the Sierras to stay (or at least to stay for a considerable length of time).

Replying to: shipo (Jul 13, 2007 9:07 pm) Oh advancing the timing definitely works--dramatic improvement in fact.
#256 of 281 Gas/Gas Mileage by dchen2003 Jul 14, 2007 (12:17 pm)
I heard some people say some of the gas is not 100% gasoline but with 10% alcohol. Because alcohol has lower energy density that cause lower MPG. Does any one know What brand of gas station use this kind of blend fuel? And what gas station has the best fuel based on your experience. Thank You Replies to this message: shipo (Jul 14, 2007 12:41 pm)

Replying to: dchen2003 (Jul 14, 2007 12:17 pm) Typically the areas that mandate oxygenated fuels (i.e. most metropolitan areas) also mandate E10 (gasoline with 10% ethanol). If you live in such an area you're out of luck as 100% gasoline cannot be had for love nor money. Best Regards, Shipo

Replying to: imidazol97 (Jul 14, 2007 3:37 pm) The proper name for "Ethanol" is "Ethyl Alcohol". Same same. Best Regards, Shipo Replies to this message: imidazol97 (Jul 15, 2007 4:30 am) shipo (Jul 15, 2007 6:33 am) imidazol97 (Jul 15, 2007 7:23 am) and 7 more...

Replying to: shipo (Jul 14, 2007 7:19 pm) >The proper name for "Ethanol" is "Ethyl Alcohol". Same same. Ethanol and ethyl alcohol are the same chemical, C2H5OH. Are you thinking you are correcting me on something? I don't understand the purpose of your post.

Replying to: imidazol97 (Jul 15, 2007 4:30 am) Hmmm, maybe I misunderstood the language of your first post: "Is alcohol being used in lots of areas now? I thought after he Katrina mess the gov advocated using as much ethanol as possible." My bad if I got the incorrect impression, but my reading of the above suggests that your language indicated that you were drawing a line between Alcohol and Ethanol. Please accept my apology if I read you incorrectly.
