Hi all, just a thought on fuel consumption, I have recently bought a 1.6sx Lacetti Station Wagon and I'm pretty chuffed with it. But I have noted that there does seem to be a huge variation in MPG posted by various people in previous topics on this and other forums.
Checking the Handbook page (3-4) yields the following information
Searching this topic on Google produces a whole gamut of opinions as to whether it does or doesnt work etc.
One site of particular interest is Thorney Motorsport's fuel tests, originally published in 2006, http://www.thorneymotorsport.co.uk/tuning/Fuel_Test_Results_Update.shtml which whilst interesting doesn't really tell you if the improvedMPG is worth the added cost. Although,after some further delving through google, Idid finda link from Tesco to a .pdf document by Thorney Motorsport which was much more useful for a fuel test done during Q3 of 2009, comparing Tesco RON95 against Tesco Momentum RON 99. Unfortunately this link is now unavailable, but I did manage to save the .pdf file to my machine and will galdly email it to anyone who wants a look, just send me a pm).
In the test they picked 8 cars to represent the different classes of cars driven in the uk at the time, for each class they claim to have picked the best selling car in that class, all were 2008 models bought privately or from second hand dealers this was to ensure that cars were not modified by manufacturers.
One part that I am unlcear on is whether they "tuned" the engine or "remapped" the ECU befor erunning on Momentum, as this was done in some of their previous tests but is not mentioned in this one.
In about a week's time I expect I will need to make my first MPG calculation. I reset the trip counter when I last filled the tank and intend to, deliberately (I am only going to do this once as I do not wish to put undue stress on my engine), run out of fuel so that I can be sure that when I fill up with Super Unleadedthere is little or no Regular Unleaded left in the system.
I will be using Tesco Momentum as used in the Thorney survey, only because I have always filled up at Tesco because they're on my way to/from work and are way cheaper than the BP/Murco filling stations at the end of my Street.
Obviously as I get the results I will post them on here.
What I would like to know from the other owners here, is what sort of fuel economy you are getting.
Specifically I am interested in 1.6SX Station Wagons, but don't be discouraged from posting if you have the 1.8SX wagon or any of the Hatchback Range so please let me know...
1) Which model Lacetti you drive
2) Age and mileage of your car
3) Whetheryou use Regular or Super Unleaded
4) Ifyou have a favoured brand of fuel that you use regularly.
5) MPG currently achieved.
For example: My Car...
1) Lacetti 1.6 SX Station Wagon (Estate)
2) 2009 (09) 41,000 miles
3) Currently using Regular Unleaded, about to change to Premium
4) Tesco
5) Don't know yet buthope it to be at least 26 MPG (www.parkers.co.uk rates fuel consumption at 36MPG)

Checking the Handbook page (3-4) yields the following information
This got me thinking about the claims that various fuel companies make about Super Unleaded giving better MPG than Regular Unleaded, especially as the handbook states that RON95 is the bare minimum to use, reading between the lines would suggest the book implies you should use fuel with a rating higher than RON95.FUEL RECOMMENDATIONS
Use only unleaded fuel rated at RON 95 or higher
Fuel quality and additives contained in fuel have a significant effect on power output, driveability, and life of the engine.
CAUTION
*Use of fuel with an octane rating number than RON95 may damage engine.
*Use of leaded fuel will damage exhaust system and invalidate the warranty.

However this .pdf, and Thorney's tests in general have been called into question on some forums and the advertised results do seem a little difficult to believe. For the time being though, I am prepared to give these tests the benefit of the doubt.Result Summary<?: prefix = o ns = "urn:schemas-microsoft-comffice
