mot time..... veg oil+petrol - Chris_90 - 13-11-2013
So my car has got petrol and Veg Oil mix in the tank will it be ok for mot? Or will it mess with the emissions?
RE: mot time..... veg oil+petrol - Mattcheese31 - 13-11-2013
just turn max fuel down if you're worried . .
RE: mot time..... veg oil+petrol - silverzx - 13-11-2013
It should be fine, just restrict/adjust the throttle cable so it's nice and slack.
Or turn the max fuel down a few turns (if on a bosch).
Other then that no reason why it should fail.
It's smoke density right? Not emission based.
RE: mot time..... veg oil+petrol - Chris_90 - 13-11-2013
No idea tbh it hardly smokes on the Veg any way it's just a haze so should be ok, guess we will find out when it goes
RE: mot time..... veg oil+petrol - silverzx - 13-11-2013
I'd be suprised if you failed.

Just booked it in for Friday so will see pretty sure it will fail on something probably not emissions if you guys think it's ok

i enquired about this when i motd my car running 100% veg, they didnt have a clue and just said bring it in, it initially failed on over 2x the legal limit which i couldnt believe as it only just smoked on boost. So i just turned down the fuel screw infront of them and it went straight through. But as a fuel it shouldnt make a difference

I ran my in veg oil turned, restricted the accelerator cable and passed no problem

Veg usually burns a whitish grey, Diesel burns black.
Veg registers alot lower in emissions as it's seen as being much less dense smoke.
Mine often reads really high on the first pass, then subsequent readings are much lower.
Always a good idea to give it an Italian Tune-up on the way to the test
RE: mot time..... veg oil+petrol - Chris_90 - 13-11-2013
It's just the petrol in mix that I'm worrying about if that will mess it up, not to worried about the veg oil
RE: mot time..... veg oil+petrol - Tom - 13-11-2013
I didnt even downtune mine, passed easily.
RE: mot time..... veg oil+petrol - bigcheez2k3 - 13-11-2013
Never done anything with mine either, passed just fine except for an advisory once for 'black smoke'
RE: mot time..... veg oil+petrol - Chris_90 - 14-11-2013
As said further up its not the Veg Oil I'm worried about its the petrol in the mix
RE: mot time..... veg oil+petrol - Piggy - 14-11-2013

And most people have said it's fine.. Good hard pull a couple of times on the way to the MOT, although from what I understand, they'll generally give it a damn hard rev prior to the smoke test anyway.
In other words, don't worry!

Last MOT, I didnt adjust mine, but i just scraped through....the limit is 1.50 whatever its measured in, and mine made 1.49!
I also took mine out half hour before it was due for the MOT, and just went for a spirited drive, delivered the car to them with a lovely warm engine, and they literally drove it straight in and did the test.
RE: mot time..... veg oil+petrol - Paul Baldwin - 15-11-2013
My 106 was MOT'd two weeks ago running on 95% veg 5% petrol. Emissions were well within limits. The only complaint from the tester was the smell giving him the munchies.

RE: mot time..... veg oil+petrol - r3k1355 - 18-11-2013
See, told you veg gets you a lower score.
Mine went thru fine this weekend too, didn't get a emissions report tho.
RE: mot time..... veg oil+petrol - Daniel306 - 18-11-2013

I no Veg Oil is lower on the emissions but as I said a few times in this thread it was the petrol in the mix I was worried about
