Unleaded additive - what's your favourite?

Have a look at the picture of the bottle using the link above - it has a little red cap. That cap is used as a measure - one capful per 10 litres of petrol. Don't drop it down the fuel filler though! Glue a bit of string to the cap while it is nice and new and clean, and loop the other end round your wrist when you pour, and you will be able to retrieve it if you drop it - as you will, one frosty day.

By the way, I have just ordered some from that website, and it accepted my order, so it looks like that is a live supplier.

and that sounds like US gallons - normally 1ml/ltr

It could be the very high compression ratio has something to do with it - causing much higher temperatures? Did you run it on super unleaded?

I think you are right.

I have just received the bottles I ordered and have done the arithmetic based on the mixing instructions printed on the label, and it comes out to roughly 89 UK gallons to a bottleful. Yet on the bottle it says "Treats 100 gallons".

I am not sure what the conversion is, but 100 US gallons = 89 UK gallons might be about right.

Jim

There's 16 fl. oz. in the US pint, so 100 US gallons is 80 UK gallons. ISTR that the US & UK fluid ounces are very slightly different measures too, but not nearly enough to explain the extra 9 gallons.

I found a conversion website - it tells me that 100 US Gallons = 83.267 UK Gallons.

It probably shows that the 100 "Treats 100 gallons" flash on the bottle is a rounded down figure.

Jim

You would have to be pretty good to accurately dispense the quantity to obtain the figures on the bottle.

I use another smaller bottle with a graduation on the side - usually an extra added splash just in case. 5ltr bottles of additive seem to last forever :)

We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember Rob saying something like:

He's wishing thinkfully.

The Honda more than likely has. Honda bikes since the early 70s had unleaded seats for the American market, so they were fitted to all models for worldwide markets. For the same reason, I'd be very surprised if a Honda car made later than that isn't fitted with them.

Not forgetting that at the time, cars for both the US and the home market would have had to be fitted with a cat.

I thought that compulsory Cats were fitted to UK K registration and afterwards. Isn't that 1990-1?

Jim

Jim Warren gurgled happily, sounding much like they were saying:

'92.

But don't forget that "the home market" for Honda doesn't mean the UK, it means Japan.
