Yak 52 owners. It looks like after a good trawl through the owners, that 91 ul is suitable for the M14P.

Many thanks Hogster :thumleft:

I have forgotten who you are - can't keep track of forum nicknames

I've updated my TB20 writeup, under "Unleaded Fuel?"
http://www.peter2000.co.uk/aviation/tb2 ... index.html

This is a very welcome development.

I think I emailed you using my real name, Rich Tebb.

OK

I wonder what the storage life of this new stuff is?

I am thinking of not only bowsers but also fuel supplied in drums, which quite a lot of people do in the more southern parts of Europe.

For reference, the EASA SIB that relates to use of UL91 can be found here.

The fuel is the same as 100LL but without the lead added. I think the mags are saying 6 month shelf life.

What people are missing is the type of valves fitted.

The O-235L2c, in 1 152 may need lead to lubricate the valves.

This link show my aircraft engine fuel requirement as 80. Does that mean 91 UL is OK? (O-320-E2A)

Sorry for the thick question!

That link is to a 2004 document. Service Instruction 1070 (in the other link) is dated July 16, 2010. I'd be fairly confident that the more recent document supersedes the old one.

From the Total Web site;

Avgas unleaded UL91 – NEW !!! UL91 is an unleaded Avgas which is specifically designed for the Ultralight aircraft. It is manufactured by AIR TOTAL and endorsed by Rotax. It can replace Avgas 100LL in a growing number of engine / aircraft combinations http://www.caa.co.uk/. It can also be used in place of mogas (forecourt petrol) which is not an approved Air Total aviation fuel.
On the airfield UL91 complements Avgas 100LL which is still required by some high powered piston engines.

Total are apparently very pleased with the number of airfields taking 91UL. By the end of Feb it is expected to be up to 15. I have asked for a list and will add it when it appears.

I've asked them to give me it and they have yet to respond!

Perhaps it would help to offer to pay something for it

our engine, TO-360-C1A6D is listed as 100LL....Does this mean there is no chance to run UL91 in it? (I am a bit confused as to what can and can't run 91UL)...

TIA
