2005 Rx 300 E10 petrol

[Rexlex]

Now covered about 400 miles on E10 and fuel and consumption has noticeably dropped to about 17mpg around town and 25mpg on the motorway 

Previously was 23 around town and 30 on a motorway

Temp has dropped a bit so might have an influence...

Not tried super unleaded yet...

Could be a new NX FSport on the cards next year😁

I've also noted a drop in MPG and a drop in performance. Hills that the car would have easily crested dropping down a gear took at least another drop in gear to get up. Not impressed with how the car reacts to E10 at all. But then the fuel could have been in storage waiting for release and could have gone off a bit.

I've gone to super-unleaded for a while. I might try E10 once things have stabilised and the fuel that has been sat months waiting for a release date has been used up.

The conspiracy theory is the fuel crisis was created to do just that: use up the stock that has been sat months and is close to being unusable.

I also noticed a drop in torque when I was touring in Devon a few weeks ago, I was manually changing gear a lot more than usual especiallly with three adults in the car and at times luggage, some of the steeper hills were a challenge!

Might try the Super for a week or two see if I prefer it.

Funnily enough it was the hills of Devon and Cornwall that showed up the deficiencies of E10 with mine. Filled up with E10 (first fill with it) to go on holiday and thought something was wrong as the cruise control tried to wring the neck of the engine getting up hills on the A30.

Almost redlined it on some of the steeper ones.
