Has Anyone Used E10 in a 95 RON Engine

[ido09s]

I have used E10 in my Tiguan by accident once and found it ran fine. Sure i didnt go giving it a hard time, but there was no sign of rough running or any warning lights that came up on the dash. Given VW dont recommend it i wouldnt do it again, but if the sticker said i could use it i would use it all the time

I do find it strange though that everyone comments on the usage of it that probably outweighs the savings. I ran my 2007 Civic only on E10 and found it went extremely well and had exceptional fuel economy. I tried running half a dozen tanks of 95, to make sure the ECU adjusted, and found it was a waste of time as the fuel economy was no better and it didnt feel to go any better either so just kept using E10. This model Civic is ok with E10 per the fuel flap sticker

The manufacturer (Volkswagen AG) states that E10 is suitable, but you need to use premium unleaded E10, not regular unleaded E10.

The situation in Australia regarding the use of ethanol blends is unclear and confusing at the moment.

The manufacturer (Volkswagen AG) states that E10 is suitable for all models (with few exceptions). Likewise, the Australian subsidiary (Volkswagen Group Australia) has indicated to the FCAI (Federal Chamber of Automotive Industries) that E10 suitable as well.

However, Volkswagen Group Australia then state on their own website that E10 is not recommended (but doesn't state it isn't suitable). It sends contradictory and confusing messages to the consumer. If VGA thinks it isn't suitable, they should make it absolutely crystal clear and prohibit its use.

It certainly is.

In NSW. there is a mandated substitution with bio-fuel required. Basically, the oil companies must ensure that a minimum percentage of bio-fuel is shipped from their depots. This sees SULP blended with 10% ethanol. If the mandated percentage is not met, then there are fines of $100,000 that can be applied.

While there are some fuels being sold that are PULP with 10% ethanol, the major oil companies are currently only offering E10 based on SULP only.

With the mandated substitution, if not enough SULP with ethanol is not sold, then service stations can shut down PULP pumps to force motorists to use E10. Failing that, they can start blending PULP with ethanol.

The other issue is that in NSW, E10 is only available in the major metropolitan areas. It is not available in regional centres or rural areas. As a result, you cannot have your vehicle tuned to use E10 if you are then going to travel to areas where it is not available.

There are major issues with E10, and it is even uncertain as to whether we can produce enough E10 should motorists embrace it. Further, the whole notion of E10 was to help cane farmers, however by far the greatest amount of ethanol is produced by distilling wheat. Cane based E10 barely keeps pace with those using E10 in Brisbane.

The NSW government HAD to keep the mandated level despite all the advice they received because the previous government had made commitments to the distillers. They were going to ban SULP, but this was abandoned following an outcry, however the mandated percentage is still something the oil companies must meet.

The local United stocks ULP 91 RON, E10 95 RON, P100 PULP 100 RON.

When I asked where the PULP 95 RON was, I was told that E10 95 RON was the replacement and United was phasing out PULP both 95 & 98 RON.

I filled up elsewhere.

It certainly is...

I was more referring to the situation (confusion) created by Volkswagen Group Australia in regards to their stance on E10 blends.

The VW consumer needs to know whether their vehicles are suitable for E10 in the first instance, before we actually get into discussing the pros and cons of E10 blends, and/or the politics.

The local United stocks ULP 91 RON, E10 95 RON, P100 PULP 100 RON.

When I asked where the PULP 95 RON was, I was told that E10 95 RON was the replacement and United was phasing out PULP both 95 & 98 RON.

I filled up elsewhere.

Assuming that E10 is suitable (as per the manufacturer), you can fill up with premium unleaded E10, which United Petroleum sell under the name of 'Premium 98 with ethanol', though I'll leave it up to you and your parents on whether it's worth it.

It might be an old thread, but United's stance only came to my notice when I filled up with their 95 (as per the fuel nozzle) only to check later as to why it was so amazingly cheap.......the docket simply stated E10 !....not sure if that's a deceptive practice.
It ran fine (PSA 1.6 THP engine and I'm not into performance) and if they are phasing out 95 for effectively 94, my major concern relates to direct injection suitability.

Well after a few emails with VW customer care, they are stating that MON is not a value used in Australia and only RON applies. So E10 95RON is acceptable to use. I even mentioned the EN228 specification for PULP as MON85 & RON95 and they reiterated that up to E10 as long as it is RON95 or above is suitable. So i guess you should be covered under warranty if you use E10 95RON fuel....

I even got a reply from United Petroleum regarding the MON of their E10 95RON fuel, they stated typically around 82.9-84.2.
Good link here explaining RON & MON Octane Number (RON, MON) | Glossary | Marquard & Bahls

BTW, i only use 98RON in my Golf as i get Costco Fuel which is the same price as 91RON elsewhere.

I’ve been using E10 for many tens of thousands of kms, and getting great economy also, in our C4 Picasso (1.6 turbo) and it says the average has been 5.3/100 , which is down to gently country cruising. The ethanol is a cleaning component also.

Happy for you but this is a VW forum

Well if you go to the FCAI E10 listing you will find almost every vehicle in the last 20 years is approved.
It’s more to do with our automotive version of ‘project fear’.

Having just dealt with an 'older' (2001) Audi, I can say that, if you plan on letting the car sit for more than a fortnight, DON'T leave E10 in it...
Run it down, and fill it back up with regular fuel.

The rubber seals in the tank turned to goo, and seized the fuel pump.
Not to mention, it smelt really bad in that tank.


That said, we ran our V5 Bora on E10 for years, and whilst you would get more km's per tank with PULP, it would still be cheaper per KM with E10. The wife also uses it in the Focus with no issues so far.
