Anyone running E10 in their VW

[Guest001]

Is anyone running E10 and is it successful Is it wise as VW "recommend" not to.

[Grugly]

Minimum is generally rated as 95. I believe E10 is classed as 94(?).

Whilst a single tank won't hurt the engine (unless your running an R engine that requires 98 min) the saving of putting E10 vs the reccomended fuel isn't worth the potential issues you will create by running less than reccomended fuel.

Also note that your ecu knows what type of fuel it is running and adjusts as needed.. but this will also apply if you try to claim warranty after causing damage from running **** fuel.

Yeah Im in the no brigade but an idiot on Whirlpool is rabbiting on about it wont hurt it and all that s**t so just asking to see on here

He probably doesnt own one and hes quoting an engineer from a country that has low sulphur fuel so is irrelevant.

Having been old skool air cooled for coming up to 50 years and a couple of T3 Watercooled in the mix when leaded petrol was canned and 98 became available the peace of mind was to go 98 and so all cars since have had 98 as the go go juice.
No different with the current rides ..... 2016 MY17 GTI 40 Years and new T-ROC 140TSI Sport.
Plenty out there trying to save $$$ but go with minimum of what is manufacturer recommended

I have saved emails from VW Australia Customer Care. They say as long as the fuel is 95RON then thats all they care about. You can get E10 from United Fuels which is 95RON. The issue is that the MON value is lower than PULP95. I raised this with VW and they said as long as its 95RON..... in any case, i only use 98RON in my Golf 110TSI...

The issue isn't the ron, blended ethanol is 120 to 135 ron and unleaded "standard" petrol is 92 ron. The simple maths are;
10% 120 ron + 90% 92 ron = 94.8 ron
10% 135 ron + 90% 92 ron = 96.3 ron

The issue with ethanol is it has only 65% of the calorific value of petrol, as a result E10 will run 3.5% "leaner", unless the ECU compensates for the ethanol content and hence adds 3.5% more fuel. I am not aware of our cars having ethanol sensors in the fuel tank, so unlikely that they do automatic compensation.

All things being equal, which they rarely are, E10 fuel usage should be around 3.5% more than Pump 95, so there is some money to be saved, but not as much as would first appear.

My question is what are you doing on whirlpool in the first place???

Also on these fuel/octane related questions the absolute best way to test is to run a tank of fuel in your car and log the timing retardation per cylinder. This will tell you how much work the ECU is having to do to keep things running.

Also to note as soon as the ECU starts to pull timing you're going to impact on the power output so even though it may run you'll be down on power.

Stirring the crap out of the VW haters and other idiots LOL

Is a fun thing and its unbelievable how many know so little about cars LOL

Will be down on power when the motor s******s itself from pinking for too long and running lean till it dies

The ECU corrects for both of those via the knock sensors and the lambda sensor. If it's outside of the ECU's ability to compensate then it will show the engine check light.

If so why then do VW say only to use it in an emergency and fill with 95 ASAP. If it did as you say it surely would be ok to use 91.

[Sharkie]

BTW, you should not be running 95 in a VW either. 95 is the MINIMUM acceptable, recommended from VW themselves is to run 98 whenever you can.

There is a loss of performance if the ECU actually reduces the ignition timing advance (retard) and adds fuel (rich). Both of which will also have the additional side effect of increasing fuel consumption. If VW said it was OK to use and people then used low octane all the time, which triggered the ECU into retard and rich, then people would complain about the lost performance and the poor (relative) fuel economy. So VW protects themselves by recommending 95 minimum. For sure it's about protection, protecting VW from customer complaints, plainly the car can handle it physically, otherwise there would be a "do not under any circumstances" warning.

Heres a hopeful owner and the very reasons why you shouldnt use anything under 95

Man wants $4000 refund for '''damaged engine''' ... but he was just using the wrong fuel | Stuff.co.nz

Do you mean e10 94 ron? No. I run that in the Accord but not in the turbo car.

I have run 98 e10 and United 100ron e10. The united 100 ron is great stuff but no longer available where i live (anywhere??)

I've also run a combination of 45l 98ron and 10l E85 (roughly e20) which gives great torque but does throw a CEL after a few hundred km. So it's not something i recommend to others. Fuel economy goes out the window too as the o2 sensors read a lean mixture and pile in more fuel to compensate.
