What is the difference Jack. Haven't paid attention since I haven't picked up any lately. Have gotten stuck using ethanol gas last couple of fill ups on our PT and it's mileage has dropped from normal rock solid 25 to little less than 20. And they say the crud is so good for us?? Corn growers and ethanol plant on other side of town from us are happy though!! -----Original Message----- From: Chrysler300@xxxxxxxxxxxxxxx [mailto:Chrysler300@xxxxxxxxxxxxxxx] On Behalf Of Jack Boyle Sent: Wednesday, January 29, 2014 9:54 AM To: 'retromobilia'; 'John L.

Chesnutt Cc: Chrysler300 Subject: Re: [Chrysler300] 110 octane gas Right on! The ethanol free gasoline is a gift. In Lower California (which in history was always leading the curve,) not now; our closest real gas is 265 miles away in a marina at lake Mead, AZ. As long as you use your car regularly you are in good shape. Here I store several cars and each gets about 500 miles per year. So stable gas is paramount. I am not certain of the modern formulation of Efree gas. Most modern fuels are built for sealed fuel systems which have no air or very little accompanying or standing on the fuel. The gas I use is built for 20 years storage in vented tanks. JJ PS: on a recent drive through the desert in, 2012 Chrysler derivative, car. I filled up with E-Free gas. I calculate the milage, by app. on fuelly.com, and that leg netted 25% better milage over the ethanol fill-ups.!? PPS: constantly running 80-90 mph traffic free old two-lane US routes, using both types of fuel. Not totally scientific but significant. _____ From: "John L.

It runs fine on pump gas and I intend to use only 91 ethanol free gas the next time I fill the tank. We have three ethanol free gas stations just outside of Portland, OR. With the 10 ½ compression the 300C goes like a bomb. We live on a hill 700 feet elevation above Portland in the West Hills. John C.

I did a 50/50 mix of 93 octane unleaded with 110 octane racing fuel in my C. After a while the car started to run rough and I was told that a lot of lead deposits and carbon was probably getting on the valves. I stopped using this mix and used a container of seafoam cleaner per tank of 91 ethanol free with a can of octane treatment which brought octane to 93. This I did for two full tanks of fuel. Car runs smooth and I don’t have any ping or dieseling in hot weather when shutting off the engine. For the 9.25:1 compression ratio on the standard 300C 392 Hemi, you really don’t need any more than 93 octane. What is best is if you can get ethanol free gas. 300’ly, Rob Kern From: Carlton Schroeder <mailto:schroe99@xxxxxxxxxxxx> Sent: Wednesday, January 22, 2014 10:52 AM To: Chrysler300@xxxxxxxxxxxxxxx Subject: [Chrysler300] 110 octane gas Hello, It just came to my attention that right here in Eagle River, WI I can drive up to a gas pump and load my 300C with leaded, non-ethanol, 110 octane gas; I just have to tell a white lie and say I am using my car for ‘off road purposes’. It does cost $7-8 per gallon and originates at a Sunoco refinery in PA. The pump actually says 115 octane but by some government definition / computation method / regulation the supplier says it is designated 110 octane. The supplier says most people (local racers) that buy it mix about 1 gallon of the 110 octane gas with 3 gallons of non-ethanol premium which is readily available around here. I think the higher octane is primarily to prevent pinging in higher compression engines and that hasn’t been a problem for me, but getting the lead-in seems like it would be helpful. I only drive this 300C 200-300 miles a year. I would appreciate advice or opinion about how to use this 110 octane gas. Thanks, Carlton Schroeder (in very cold and snowy Eagle River, WI - snowmobile capital of the world) [Non-text portions of this message have been removed] [Non-text portions of this message have been removed] ------------------------------------ To send a message to this group, send an email to: Chrysler300@xxxxxxxxxxxxxxx To unsubscribe from this group, send an email to bob@xxxxxxxxxxxxx or go to http://autos.groups.yahoo.com/group/Chrysler300/join and select the "Leave Group" button For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm For archives go to http://www.forwardlook.net/300-archive/search.htm#querylangYahoo Groups Links --- This email is free from viruses and malware because avast!
