Dont use United Premium. Yes it is 100RON, but its also got 20% ethonol. A great way to bugger your engine.

United Petroleum's Premium 100 contains no more than 10% ethanol and as such, will not damage your vehicle because most VW models are compatible with E10 blends.

In regards to the theme of this thread, it may be better to avoid ethanol blends if fuel consumption is a high priority.

Any more than 0% ethanol is enough to keep me well WELL away XD

All I will say is less embodied energy but a cleaner burn....

The 1.4tsi is not an ethanol approved engine. Have checked before.

Depends who you ask.

Volkswagen AG states that their vehicles are compatible with E10, with the few exceptions listed on a PDF file. The website also has a VIN checking service to see if your vehicle is compatible; copy and pasting a few Australian VINs indicated they are compatible.

The Federal Chamber of Automotive Industries (FCAI), of which Volkswagen Group Australia Pty Ltd is a member company, indicates that fuel-injected models post 1986 are suitable for use with E10.

Volkswagen Group Australia on the other hand, states on their website that ethanol blended fuels are not recommended, but does not clarify further whether the vehicles are suitable or compatible with E10 on their FAQ page.



Who stated that the 1.4 TSI engine (which is widely used in the VW group) is not an ethanol approved engine? This is an important distinction that needs clarifying and if it is contrary to what is indicated on the FCAI website, someone needs to be alerted.

Is the United 100RON more expensive than 98RON at other stations?
If so has anyone tested 100RON with 10% Ethanol for fuel efficiency?

The previous Fuel Efficiency tests I've seen with same model cars, and cruise control showed that E10 95RON and 98RON in that order were the best value for money

A few people on this forum have used United petrol & desiel only to have a fault light come on - fuel filter had to be cleaned

At the MRT Track day they recommended Caltex 98 followed by Shell 98

Ethanol emissions can damage the core of catalytic converters

Ethanol has less energy than petrol, you have to burn more of it to achieve the same outcome, this needs to be factored into the price/economy equation - if the price differential is wide enough E10 can be the cheapest to run, but not by much

(If you have a turbo VAG car then 95 and 98 fuels would be the go)

Actually they had this exact kind of test done in the cars guide comparing between the performance/fuel economy and price of different types of fuel.

Any petrol that had a blend of ethanol was the most expensive to run because of the fact that is has less energy (not to mention screws up your engine.

91 still worked out the be the cheapest and 98 coming second. The test was conducted on a Holden captiva 7 (60l tank) because it can use up to E85 blend.

Fuel economy results are as follows:

E85 - 14.6l/100 (413km) @ $1.19
E10 - 11.9l/100 (514km) @ $1.34
91 - 11.1l/100 (536km) @ $1.36
95 - 10.7l/100 (569km) @ $1.44
98 - 10.2l/100 (600km) @ $1.50

Cost over 20,000km:

E85 - $3472
E10 - $3187
91 - $3017
95 - $3080
98 - $3058

Think the results speak for them-self!

Checked with VGA and seeing it is they who provide the product warranty, not VAG then I would take their advice.

In fact if memory serves me correctly the owners manual might make mention of it also but I'm not 100% on that.

I'm all for the use of ethanol blend fuels but everyone always goes on about the use of non approved oils, it's much easier and far more common for dealerships to be ordered to take fuel samples. Do you suggest people tempt fate by using ethanol blended fuel during the warranty period?

Agreed, except that the typical e10 is around 93-94 Octane (Shell)

I've not seen a test done with 100RON with e10, and would be interested in seeing it in a comparison
