RE: [Biofuel] Fwd: Acetone as gasoline additive tests - Phase II
Well I have a result for you all - but not as you would expect: NO ACETONE 39.4l petrol used Miles covered = 186.9 mpg = 21.35 WITH ACETONE 42.73l petrol used Miles covered = 185.6 Mpg = 19.55 Obviously measuring over 186 miles is nowhere near sufficient in terms of scientific sampling really there are too many variables in every day driving that would need to be eliminated to get a more accurate result. One point I have to admit is that I have been dashing here there everywhere in the last week getting ready for our holiday so I could easily have been more heavy footed this week than last week. As I said before though, the engine did seem to run better, quieter with a bit more power did not seem to be running rich as before. When I get back I'll have another go see what happens.

RE: [Biofuel] Fwd: Acetone as gasoline additive tests - Phase II
Doing an mpg test at the moment Keith, another 130 miles to do before I can report back. What I will say is that the engine seems to be running a little smoother, quieter with a bit more power - not very quantitative I know. One observation I've made is that the engine before was running rich - with acetone as an additive the distinctive sweetness of the exhaust fumes has gone, they smell more like that of a well tuned engine. Again not very quantitative. Hope to have an mpg comparison next week Take care Malcolm -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Keith Addison Sent: 29 April 2005 18:51 To: [EMAIL PROTECTED] Subject: [Biofuel] Fwd: Acetone as gasoline additive tests - Phase II Any further results from Biofuel list members yet?

Acetone's a better subject than acetylene eh? LOL! (Phew!) By the way, we took that tank back to that engineer, and he wasn't at all perturbed by what we told him. Oh, he said. Hm.

RE: [Biofuel] Fwd: Acetone as gasoline additive tests - Phase II
In addition to mpg comparison, it will be useful to know the age and size of the engine, the type of fuel delivery system, the fuel used, and the amount of acetone added. m-- Doing an mpg test at the moment ...the engine seems to be running a little smoother, quieter with a bit more power - not very quantitative I know.

Re: [Biofuel] Fwd: Acetone as gasoline additive tests - Phase II
Re: BUT I'm wondering if there were differences between tanks because of the gas. I mean to say that there might be fluctuations in the gas delivered to the same gas station. Since (as I understand it) the same gas station was used, perhaps the difference is in the pumps. ...just thinking out loud.

Regards Keith Fwded message: To: wastewatts From: Dave Brown Subject: [wastewatts] Acetone as gasoline additive tests - Phase II Reply-To: [EMAIL PROTECTED] Last week I posted results of 3 tankfuls of gasoline containing acetone as an additive at about 3oz per 10gal of gasoline. Summary of findings were: Over all: Just about averaged 2.4oz/10gal of acetone Distance/consumption: 1,245mi, 62.00gal Result: 20.08mpg Tank 2 and 3 only: Pretty darn close to the 3oz/10gal recommended acetone level. Distance/consumption: 859mi, 41.95gal Result: 20.48 So next I operated my van a similar distance under similar, although not strictly identical, conditions. Here's what I got. Tank 1: Still had some acetone remaining, I estimate about 0.25oz per 10gal of gasoline. Distance/consumption: 416mi, 20.184 gal Result: 20.6mpg. Notes: Mixed feelings on this tankful, as I'm sure the acetone in earlier gas fills probably cleaned out my injectors and stuff. Still, it wasn't any practical difference from the acetone test. Tank 2: Any acetone residuals in the tank now are nil and not worth figuring or considering. Distance/consumption: 445mi, 26.556gal Result: 16.76mpg Notes: Huge drop, and trips were relatively consistent with those taken for the acetone portion of tests. I doubt that any minor temperature fluctuations during this testing period could account for this much change. Tank 3: Shouldn't be any acetone left other than a stray molecule or two. Distance/consumption: 396mi, 23.017gal Result: 17.2mpg Note: In the same relative ball park as the last tankful. Over all: 1257miles / 69.757gal = 18.02mpg Tanks 2 and 3 only: 841miles / 49.573gal = 16.96mpg Huh? That's a big difference. The skeptic in me doubts it should be so. An overall difference of 2.78pmg that says that the acetone provided for a 15.4% improvement. Or a tank 2/3 comparison that results in a difference of 3.52mpg that says that the acetone provided for a 17.6% improvement. If this is all true, then I'm going to become a devoted fan of the acetone treatment. BUT Yesterday I made a trip to the western suburbs of Chicago, IL. I tanked up as I was leaving Green Bay, WI and tanked up again at the same gas station when I came back. This was 397miles 380mi highway, 17mi local streets). How'd I do? 397miles / 18.65gal = 21.3mpg. ? That's right up there with the best of the acetone treated gasoline. Only difference is that this last tankful was consumed at nearly all highway speeds. Makes it different from the other tankfuls, but it still makes one wonder. Conclusion: The test must continue. Since I've got straight gasoline in the tank now, I'll continue the record keeping for another week or so. Then I'll go back to acetone addition and run a comparable set of miles. I'll report back later as further results come in. In the meantime I'm tending to lean towards concluding that the acetone helps. I know my engine runs smoother with it. It was evident when I first added the acetone and the engine is now back to it's old tricks without the acetone.

RE: [Biofuel] Fwd: Acetone as gasoline additive tests - Phase II
Hello Keith, Mike et al It goes well thanks...busy as ever. Acetone's a better subject than acetylene eh? LOL! (Phew!) By the way, we took that tank back to that engineer, and he wasn't at all perturbed by what we told him. Oh, he said. Hm. Beware of certain engineers bearing gifts. Yes, thankfully the boom is IN the cylinders not on the outside. Phew indeedy!! Bloody engineers...give 'em a few spanners they think they know it all!! What motor is that Malcolm? Sorry - should have said. The Range Rover is off the road at the moment, the flex plate (links torque converter to crank) shattered so while I had the auto transmission off to replace the flex plate I thought I'd swap the trans for a diesel matched one I got on ebay (when the conversion was done they left the petrol matched trans in the shifts were never right) I've just finished rebuilding the new trans as it had water in it, so hope to try it out next week. In the meantime we bought the current runabout from my niece for £250 because it needed a few bits doing to it she just couldn't afford the repairs - usual story £150 in parts but £650 in labour. She was given a later model by her mum dadaren't parents great! It's a 1989 Volvo 740 GLE - 2.3l petrol, non turbo. It's a bit thirsty for my liking but hopefully we won't be using it as the main vehicle for too much longer. We mainly do school runs, weekly shop, pick up drop off customer's furniture etc. So it's town driving with about 10 - 15% motorway. My initial mpg without acetone (measured over 186.9 miles) = 21.346 As I said it was running rich. 110 miles left to cover on the acetone mpg test so I should have a result by mid week, hope so as I'm off to Spain for a week on Thursday. :-) I'll keep you posted.
