91 octane unleaded

Our man in Havana

I noticed that out in eastern Europe eg Austria there is a 91 octane unleaded sold everywhere. Most cars I have ever had use 95 octane.

What sort of heaps run on 91? I think I may have accidently put that 91 crap in my rental car in Hungary last week, it would account for bad acceleration.

Thatll kill any jap import turbos. The ceramic turbos hate that stuff and there not fond of 95 either.:D

not just in "eastern Europe" ...take Germany for example:

Back in the days of leaded fuel you used to get "normal" or "regular" (91 Octane) and "Super" (98 Octane)

Then when the lead dissapeared, for a time all you could get was "Eurosuper" (95 Octane) and now there is "nmormal unleaded" (91), "super" (95) and "super plus" (98)

Almost every engine that isn't highly tuned will run happily on 91 Octane. Having said that ...more and more modern engines (big or small) are now so optimised that they need at least 95 Octane.

But for a lot of people it is still important to buy a new car that will run on 91 Octane ...it is just so much cheaper in the long run (usual difference is around 5 cent per liter)

That, btw, is the reason why you get some VW/Opel/Ford engines that have a fairly "weedy" power output per cc (especially in comparison to Jap engines) ...they are designed to run on 91 Octane.

I remember once on holiday in Austria accidentally filling the MX-5 up with that stuff. It drove like a pig especially when we decided to drive over the Gothard Pass ... I was being overtaken going uphill by virtually everybody

P.S. I'm sure the Austrians would love to hear that their country is considered to be in 'Eastern Europe'

It is more suitable for ;

economies for which the market would perfer a cheaper fuel sacrificing performance, with less sensitive vehicles to suit (NOT an Intergra Type R!)

optional in countries where vehicles stay on a near constant speed, on long runs on say motorways

Most cars here would be 'pinking' like crazy with that stuff.

I take it it was never sold here.

Must work well in the trabants and the pre freedom skodas.

peasant

Nope ..Trabants are two-stroke ..they run on a 1:25 mix:D

Ba$tard

Heh, or you could opt for the luxurious Trabant 1,1 later on....which had the upgrade to a small 4-stroke VW engine...WOW ! Why didnt it catch on in Ireland...

Bet you wont find a rusty one

Bet you wont find a rusty one

not on the body panels ...the ware made from cloth soaked in epoxy "Duraplast" ...no sheet metal there...

My Jetski is supposted to run on 91-92 Octane ... Wonder where I could get it in Galway

We have only RON 95,98,99 or 100 petrol in Hungary since ages...

I think most two-stroke engines would run quite happily on this?

Depends on the compression ratio really. Chances are it will run hotter with it anyway.
