Some states now have "The 5 minute rule". My state does and local cops are being trained to look out for it. Hefty fine if your caught.

Marshall Booth used to lecture us to start it, note when the oil pressure reached three bar, then drive off hammering hard and unrelentingly. No earthly reason to let an IDI diesel idle like that. If he were still amongst the living he'd give a stern all-CAPS rebuke to such behavior

WOW lol, its been what, eight hours since i posted this? Now its not like i put ten gallons of gasoline in there with two gallons of diesel, i thinned the gasoline out with five gallons of diesel. 5:1 ratio. the gasoline will clear out the soot and crap in the combustion chamber and fuel system, as long as the IP is lubricated it doesnt care what you put into it. Valves are fine, didnt get it hot enough to hurt anything. Seems to be running fine to me, This morning it started up as usual with the flick of a key. Im going to call it carbon deposits in the exhaust burning up. Lol, i didnt just "let it idle" i started it, expecting to come back out in about ten minutes (just getting off of work) then my foreman asked me to do something before i left. im just experimenting? if i can mix gasoline with diesel, i could have a real cost savings. its allmost a dollar diffrence in diesel and gasoline where i live. Not only that but maybie a power increase as well? Well im not going to do the gasoline mix again, because it knocks abit more at idle and ide rather not have the ring seats beaten to death. Fun though, you actually got a little more performance at high rpms. and less soot.

Gasoline does many bad things to diesel engines. If you want to do cleaning, use a proper diesel fuel additive...not gas. Octane in gas actually inhibits the cetane in diesel, causing reduced efficiency and burn. What you want is to INcrease cetane...so use an additive.

The tank in a 240D is what, 17 gal? So you had 12 (say 10) gal of gas and 5 gal of diesel?

I agree with soot or carbon burning from the slightly elevated temperatures generated with gas in the mix. You are allowed to add a certain ratio of gas to the diesel as a fuel thinner in cold weather. I thought it was 20%. May not be the best choice but it is in the owners manuals of volkswagons at least.
Now that you have been raked over the coals so to speak. I thought I might chime in. Main thing is to watch for that tree at the bottom of your driveway. I cannot remember if it survived or not after it jumped out into your path. Seems hitting trees is just more socially aceptable behaviour. I hope I am right as I thought it was you. I sometimes make misteaks though. |

I am certain that the manuals that recommend gasoline as a mix in diesel fuel are only recommending it when the fuel is at or near gel temps...like 20bleow zero or something... to thin the fuel enough to drive... not for normal driving...

But there really isn't any reason to use motor oil at all. But if you feel the need to "lube things up" then a quart of oil (in a full tank) won't hurt anything.

id imagine used motor oil has metal and stuff in it that would get deposited in the engine. Things you cant really filter out.

Wow gas in a diesel, I'm going to grab some pop corn and a beer and sit back and wait for it to self destruct.
Its official you cannot say anything against the WVO guys anymore, your just as bad!

The manuals after the mid 80's (84 I think it was) say to use kerosene instead of g@soline.

1. Adding gasoline in the older benz diesels was approved in cold weather when no winter blend was available. I wouldn't recommend it in warm weather.
2. Adding motor oil if its clean would be ok. 3. Hitting the rev limiter every shift is not a terrible thing but its useless as it really does not improve the acceleration over shifting at about 80% of the max rpm. 4. Revviing it in neutral is silly but not horrible. I would not do it. 5. I don't know what is causing the sparks but they don't seem like a good thing. 6. Diesels imho do not need anything done to blow out the carbon if they get driven on the highway on a regular basis and are in good running condition. 7. Cervan is certainly likable but has some unusual ideas. Tom W

thankyou walgamuth. Im going to guess im kind of socially diverse? lol. Hattersguy lol, get your beer and popcorn but that engine isnt going anywhere, and i can prove it.
http://s8.photobucket.com/albums/a2/Cervan/?action=view¤t=Video009.flv BTW does anybody know the R/S ratio in these engines? I would immagine with such high RPM's they would be under square. hmm... maybie i should lighten the flywheel abit.. Would only work if the car lost some beef as well, or else i would have a harder time getting it off the line.

the 240 has 91 bore / 92 stroke.
lightening the flywheel won't help your economy much. It may make it trickier to take off but the main purpose IMHO of a heavy flywheel is to smoothen the vibrations. Tom W
