Killing the cycle, mid purge with key out.

[Jack_Toepfer]

I don't know how to explain it better for the title.

I've done it 2 times now.

Basically, when I park the truck and pull the key, the truck stays running. At this point it is purging. For these 2 times, I've placed the switch in the off position to kill the truck. I'll be returning shortly, and I'll be able to start it on veggie, no need to run it on diesel. After toggling to off and then back to Auto, the truck is off, and it will start on veggie.

I'm not hurting anything by doing this am I?

IMO you shouldn't do this because eventually you WILL be away from the truck longer than suspected and coem back to a cold engine witl vegi in the lines.
Also your V3 module will cool off much faster than your engine so even though you come back out to a hot engine, if you were to take a temp reading on the vegi lines and module you would find that the temp has cooled alot...meaning your goiun gto start the truck with cool vegi in those lines.

About the only time I'll switch it to off and immediately kill it is if I'm in the drive through at a restaurant. Then the truck is only off for 15-20 seconds.

Otherwise, I'll let it run the cycle everytime.

I do this also....

Honestly though... I've let it run out, and returned to the truck 10-15 minutes later and the V3 is on before the truck is done turning over.

Anything over 15-20 minutes I'd worry about it in the summer. I won't be doing it at all in the winter.

My concern wasn't with having vegi in the motor, but killing the V3 mid purge/run time.

No it won't hurt the V3 to do this but i honestly don't understad why you would want to take a chance and not purge it. I have been guilty of doing this in the past and i parked in the driveway, killed it without purging (in winter) and was going to run in and use the bathroom and come back out and drive to the store. Well the phone rang and i talked for 2 hours to my brother long distance, when i was done talking it was too late to go to the store so i decided to do it the next day - i forgot all about the fact that i had not purged. It wasn't super cold as i remember it but the next morning my truck hated me and all i could think about was the carbon i was creating inside.

Some one is playing Russian Roulette,but doesn't know it.Remember the V3 is your engines fail safe,don't let it be your downfall.So say your at the store,only planning to be in store 10 min,you stop mid-cycle.While in store you run into so and so from High school,etc,etc.You can either A) cut conversation short to save 15cents worth of diesel,B)stand there watching clock not enjoying this long lost friend,Or my favorite,C)all of the above but add on getting out side truck won't start then You are out $50-$100(a least) for the tow,and then either your time or someone elses to drain fuel rails.I love not buying #2 also but if you bought the best kit,with the tallest price than let it do it's job.....not trying to be a (censored) ,but i always look at worse case scenario..grease out

I hear what you guys are saying... but let me put it this way

- I'm not that dedicated to my brothers.
- I would immediately take the conversation outside so I could show them the V3



I really only do it when I know it will only be a matter of time that I return to the truck.

I take your comments home with me though. Thanks.

I agree, the V3 is engineeered to work a certain way and lots of folks are trying to unengineer it to do as they think is best...which is your perogative but it will catch up with you eventually.

I only do this in the bank line and the resturant line I do not even do it in the post office because I never get in and out of there with out the guy in front of me either wanting a passport photo or a cashiers check.

Come on guys... 15 minutes isn't going to gel the oil.

There are times where leaving the truck running just isn't necessary.

Gelling the oil isn't the issue...starting on cool oil that may be down to ...oh say 80-100 degrees is an issue. And that uninsulated fuel line from the V3 to the heads will cool off fast when the ambient temps are down even to around 50*
Take a temp reading post V3 sometime after thew truck has sat for even 15 minutes in 40- 50 degree temps.

JackT,
Why not turn the V3 off prior to turning the key off vs the way you are doing it now? I would let the system purge, but if you want to do it why not do it with less stress on the system?

Thats why I said I've only done it twice. Both were by accident. I always kill the kit prior to shutting off the truck when I remember.

Like I said... my concern is the V3, not my truck. I know the oil in the lines and the heads on the motor are still well above 150* after 10 minutes of down time. When it is 10 below... I will not be doing this.

Its been 80* out here lately during the day and 50s at night. I'm only doing it when I know I can get away with it.

Like my first post implied... it was accidental that I shut off the truck prior to shutting off the Vegistroke.
