F.a.o. Mk1 & Mk2 n/a owners

Received an e-mail from Shell today. The change is effective from 1st September. Just 4 weeks away.
V-Power remains E5.

The same will doubtless apply to other brands.

My local Asda has already converted to e10 only, Morrisons, Shell & BP still have e5 at the moment.
There's still a lack of accurate information on what exactly in the the likes of a MK1 is adversely affected by e10, there's a lot of conflicting info/articles out there, difficult to know what to believe. :confused1:

E10 has a considerably lower calorific value and the mk1 is a closed loop fueling system, it does not monitor burn efficiency and toyota mapped it on the fuel to be within a particular range of octane and calorific values. it cannot compensate for a change in the fuel as a modern car will by monitoring exhaust gasses and knock.
E10 might just be scraping in at the bottom of the mapping range it really isnt known so its just not worth the potential engine damage.
I will be running my mk1 on premium.
My mk2 as it has a 2002 v6 and will be ok on e10 but i will be changing the rubber lines to ones rated for it and i am very tempted to get some tank sealer to help protect the tank from inevitable corrosion from it.

E5 available at my local Sainsbury and Tesco alongside E10. Wiser to use this not E10

Have had trouble on older cars even on E5 being more volatile and damaging fuel lines

AIUI it's less about internal engine damage per se than its longer term corrosive effect on ancillaries (fuel pump seals, rubber hoses, etc.).

It's also more hydroscopic which is not good news if your car is used infrequently. If laid up over winter, might be best to drain the system.

Turns out fuel with added alcohol isn't exactly new in the UK, it was available from the 30's to the 60's https://www.gracesguide.co.uk/Cleveland_Discol. Also came across this https://www.theautochannel.com/news/201 ... g-oil.html

I remember Cleveland Discol petrol pumps in the 1950s. :) A garage in our local town had them.
I was a bit too young to have a driving licence back then though, so paid it no mind.

Rather than second guess I contacted the organ grinder. This is their reply (my bold).
Toyota (GB) PLC wrote: Thank you for your email.

The information we are giving our customers regarding the E10 fuel is the following:

All European petrol models made from January 1998 can use petrol blended with max 10% ethanol (E10) with the exception of the following models:

– Avensis 2,0 L made between July 2000 and October 2008.
– Avensis 2,4 L made between June 2003 and October 2008.

Thank you for contacting Toyota and have a great weekend.
Hmmm. Mk2 production continued past that date (Rev5).
https://www.mr2oc.co.uk/know-your2/mr2- ... dates.html

Which obviously begs the question did anything change on later 3S engines to make them compatible?
I rather doubt it, but I'm going to go back to Mr T after the weekend for clarification.

I've received confirmation from Toyota (GB) PLC's Technical Department regarding late MY UK 3S-GE Mk2s.
Those with a production date* from January 1998 onwards can use E10. To find that out you'll need the VIN number.

Then ask jimi nicely if he can check it for you. :)

* n.b. You can't use the date on the V5C for this (T2's is April 1999 but according to Mr T was built in January.

If I can muscle in on this thread with some questions.
Say I'm doing a tour of Northern Scotland and I find my tank is low and I can't find any E5 anywhere, how long could I run on E10, provided I refill with E5 as soon as I do stumble across some?
On availability; in Chelmsford, ASDA are only doing E10, but Shell have E5, but at 22p per litre higher than E10!!

There were no relevant changes to the fuel system for Rev5 vs Rev3 and Rev4 for UK market cars according to the parts catalogue. The only change I can see that may have anything to do with E10 is one of the injector O-rings changed 12/1998, which doesn't align with the January 1998 date. I suppose its possible the compatibility is due to differences in the map (E10 has less energy due to the ethanol content), but then that would mean Rev4 UK would be fine too.

I would be surprised if Rev3 / Rev4 UK market cars had any problem with E10.

I wouldn't have thought a couple of tankfuls would be a problem. Don't hold me to it though.
Depends on where in Northern Scotland you're planning to go.
Super Unleaded is not readily obtainable north and west of the Great Glen (A82).
Ullapool (where I usually stay) has it (last visit October 2019).
Ditto Kyle of Lochalsh, plus Broadford in Skye.

Shell V-Power will definitely remain E5 for some time yet.
I don't know about other brands' Super Unleaded but the same may well apply.
Easiest way to find out is e-mail them and ask.

Good luck with finding a Shell filling station in the Highlands though. :)
They pulled out of that market segment more than a decade ago.
There is one in Inverness and that's it.

Quite, but the response from Mr T is what it is.

Lucky we don't have to worry about Ethanol fuels over here, having said that it looks like we are going to close refining in NZ at Marsden Point which is New Zealand's only refiner.

Marsden produces 70% of our Petrol so we will be shipping in finished product which will be interesting. The quality of our Mobil 8000 which is a 98 Octane has certainly been excellent and I run it in everything.

I guess it could go either way with either some 100+ Octane available or hopefully not the worst possible option of having no fuel available suitable for older cars like the MR2.
