hjtrbo Posted December 4, 2021 Share Posted December 4, 2021 Hey all. Last 3 fills at different Uniteds (Yarragon, Traralgon & Hallam) I've noticed my sensor not displaying 85 anymore like it used when I last used e85 about 6 months ago. Anyone else noticed this? Or should I look at what's involved to re-calibrate my sensor? Quote Link to comment Share on other sites More sharing options...
hjtrbo Posted December 4, 2021 Author Share Posted December 4, 2021 Sorry should of added, gauge is displaying 80 - 81. Quote Link to comment Share on other sites More sharing options...
jakka351 Posted December 4, 2021 Share Posted December 4, 2021 Hi, E85 sold in Australia does not have to be 85% ethanol, it can actually be in the range of 70%-85%. If you are filling up at the servo it is going to be very hit and and miss - both with regards to ethanol percent and fuel quality especially at the one that sells E85. I would invest in a means to detect water in your fuel as well - with petrol, water will not mix and will sit at the bottom of a tank, but water will mix with ethanol. With E85 the water can form an azeotrope and become "mixed" in a sense. Maybe consider buying by the 205 L drum from a racing fuels place? They should be able to guarantee quality and content.

hjtrbo Posted December 4, 2021 Author Share Posted December 4, 2021 The label on the bowser says "always 85% ethanol". Misleading. I'm going to get in touch with United to clarify. Thanks @jakka351 for the info. The bowser at Traralgon is better as it's been enhanced by Independent Motorsports according to another label.

jakka351 Posted December 4, 2021 Share Posted December 4, 2021 Just like all the 98 pumps say 98 Octane *RON Quote Link to comment Share on other sites More sharing options...
jakka351 Posted December 4, 2021 Share Posted December 4, 2021 according to this the bowser should display "contains 70-85% ethanol". You have been mislead by the labelling, so maybe you have something. I dont think they will be very helpful though. https://www.legislation.gov.au/Details/F2019L01281 1 Quote Link to comment Share on other sites More sharing options...
hjtrbo Posted December 4, 2021 Author Share Posted December 4, 2021 Sent them an enquiry. Would be good to know. Currently road tuning and am at timing and boost stage. If it's not always 85% but in that range you mentioned I'll add some unleaded in to drop it down to e70 and tune from there. Thanks. Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted December 12, 2021 Share Posted December 12, 2021 In SA it is E83-E85 100% of the time I've filled up in the last 3 years via United. You can measure how much water it absorbs as well, eg one car had it sitting for 6 months and the E content went from E83 to E89. Probably not much water as the dielectric constant of water is something like 1000 vs 18 for ethanol, but it definitely absorbed some to raise it. 1 Quote Link to comment Share on other sites More sharing options...
jakka351 Posted December 12, 2021 Share Posted December 12, 2021 Service station attendants also like to forget to tighten the dip point caps when taking the daily tank levels on sites that dont have digital tank gauges, so dont fill up after a flood! 1 Quote Link to comment Share on other sites More sharing options...
