mot time..... veg oil+petrol

[Chris_90]

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?

[Mattcheese31]

just turn max fuel down if you're worried . .

[silverzx]

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.

[Chris_90]

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

[silverzx]

I'd be suprised if you failed.

[Chris_90]

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

[Chris_90]

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

[Tom]

I didnt even downtune mine, passed easily.

[bigcheez2k3]

Never done anything with mine either, passed just fine except for an advisory once for 'black smoke'

[Chris_90]

As said further up its not the Veg Oil I'm worried about its the petrol in the mix

[Piggy]

well with petrol burning cleaner than diesel or veg...whats the problem?

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.

[Paul Baldwin]

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.

No idea what it means but it passed so all good decide if I'm keeping it now

[silverzx]

You flew through.

[Tom]

Easy peasy!

[r3k1355]

See, told you veg gets you a lower score.

Mine went thru fine this weekend too, didn't get a emissions report tho.

[Daniel306]

1.5 1/m The test limit should be 3.0 1/m, thats what all my Mots say

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
