just needs a tune touch up that's all.

How much power difference from the 110? Didnt Dion convince you its cheaper to run 110 all the time instead of the e85? (Are you trying the caltex e85? or 205L drums)

I think dion sells the 205L drum for like $420ish? I could be completely wrong but that rings a bell when I asked. More power and more KM per tank when using 110 over e85. Not to mention you can use normal fuel lines etc.

yes fordriver1

Caltex is fine, been using it and United for awhile now, no issues.

Dont drive it like that, going from petrol to effy requires a full tune, not just a touch up... but in saying that Ive flash the stock tune into mine with 80s and E85 and it started and ran fairly safely with ok AFRs.

I would recommend to anyone using E85 from various servos to spend $300 and fit a wide band 02 sensor / gauge, that way IF there is a variation in fuels you'll be able to see the AFRs change in cabin, and roughthly alter the tune via the xcal3 hand controller to suit... cheap insurance.

I've read Caltex goes as low as 70% in winter...

United stays around 90 all the time...

Read this on mrparts.com.au, they have performed an ethanol content test on both united and caltex (Melbourne outlet's)....

Caltex Vs United.

Which is better?

United have long been selling their blend of E85 in a very select few service stations in Australia for a while now. Caltex, the new kid on the block, has done a deal with Expensive Daewoo which will see roll out of their ‘bio e-flex’ E85 fuels across Australia.

As I had a 20L drum of the United E85 still in the garage, and had just purchased 80L of the Caltex bio-eflex, I thought id do a test to see how they came out.

United does not have a winter/summer mix. It is always E85 (85% ethanol, 15% 91 RON unleaded).

Caltex bio-eflex do however. During colder months from march to november, Caltex state their bio-eflex can range from 70 to 85% ethanol.

The test was conducted using the quickfuels e85 test tube test kit. The test involves filling a test tube with a certain amount of water, followed by a certain amount of your E85. Once settled, the petrol precipitates out of the mixture, leaving you with your % of ethanol.

These are the results.

To my suprise (and I had to conduct the test 4 times to make sure of this), the United E85 would not precipitate to anymore than 5%, meaning, according to the test, the united batch I had was closer to 95% ethanol (as apposed to the 85% it is meant to be).

At first I thought the test may be a gimmick and not worth even doing.

I then however tested the caltex e-flex. Now Caltex state the winter mix period runs up to the middle of November, so I expected there to be somewhere in the low 70′s amount of ethanol in this fuel.

This is the result. Baiscally 72% ethanol, confirming what Caltex basically state bio-eflex contains during their ‘winter’ mix period.

So what does this mean?

Well, my current tune, if this is correct, is based on an ethanol mixture of 95%! Now with the new petrol only containing 72% ethanol, it means I will probably need to take a little bit of fuel out of the tune (as it was already very fat and safe on the united e85).

The united fuel has that characteristic sweet E85 smell, whereas the Caltex bio-eflex at 72% ethanol has an overpowering unleaded petrol stink to it.

Whats more, the caltex is $1.09 a litre. I can only assume this is because it currently has 28% unleaded in it, and it will be under $1.00 a litre (like the united E85) when the summer 85% mixture is in the bowser. If not, then that's a bit rich from Caltex to charge customers over $1.00 a litre for something made from sugar waste.

Definately be taking Rapid's advice and fitting a wideband, cos if your running say Caltex E85 and it's around 72% as stated and go to the higher United with 95% content then your engine will be running lean and with high boost and lean mixtures will end up costing you alot more than what a wideband will...
