Poor winter fuel economy

[nigelb]

I know a little about their bioboost product. I took delivery of some a few years ago and contains 2-EHN at about 30%. Can contain up to 70% methanol.FFS

This product was sold to me in a leaking container. Complained about that and they then sent me another....which also leaked. Some people never learn. Ah well!

Interesting.  What ratio are you dosing?  1:1000 or slightly stronger?

I'm using 1.6:1000 or 40ml/25ltr.

I used to dose 1.5:1000 but 2 x 20ml syringes is a lot easier (it's me "I don't give a shite" pills wot do it).

I've added 35ml to the estimated 35l in the tank, if that's OK I'll dose the next 25l with 35ml too at Jim's ratio of 1.5:1000.

What is the effect of overdoing it?  Knocking?  I'm bringing 25l of bio with me to dilute the tank with just in case, though at 1:1000 I gather I'm unlikely to see any issues.  I think if anything my fuel pump is slightly retarded.

Over dosing can cause a serious leak in the bank balance akin to pouring money down the drain.

It can take a while to find the right dose for your vehicle, increase the dose by 0.1ml/ltr until the increase in benifit stops or reverses then go back to the best result.

My recollection of these types of additives is that dosing levels reach a plateau where increasing beyond it either does nothing or can reduce effectiveness. So as Jim say's a waste of money.

[Tony]

In all fairness though overdosing by an extra 0.5:1000 is what, 25ml per 50l tank or 32p per tank... some people are paying that per litre of oil.

True but you wouldn't give me 32p every time you fill your tank would you, you don't mind giving it to your supplier though.

I dare say you're right Steve. It's a long winded but essential process to find out what the optimum is. At the moment I'm at 3ml but start a reduction program on my next fill up.

I tell you what, this 2-EHN is good stuff.  Even at the low dose the engine is a lot smoother following cold starting, and I'm not pushing the throttle anywhere near as far to keep it rolling at 30mph.  It's a bit early to know what the effect on fuel efficiency is but I'm pretty hopeful about this!

Interesting. Got to be good if it needs less throttle.

Welcome to our world                                 eventually.

Aye..I dare say you're right.

I'm not very often wrong but I'm right again.
