Target Reached 70mpg!

JohnX_2

In 2006 I posted this image on a motoring forum showing an average mileage of 60mpg over 1031 miles ! in my trusty Passat !
There are some important differences though, this ones no slouch with a blistering 130bhp, far more powerful than most other diesel engines!
Note though that this mileage is mostly on long trips on country roads with an average speed of 50-60mph!

Plus this is no small matchbox-Its a big solidly built car which I feel more safe driving in!

Secret to achieving this-Cruise control!

70mpg :shocked: Some of us dream of above 20mpg :rotfl::j

im amazed at how many people believe that the manufacturers MPG indicators are a good unbiased represenation of fuel economy, has anybody contacted a manufacturer yet to find out how accurate those gimmicks really are? My friend has a corvette Z06 (505 hp, 193mph v8), on occasion the economy meter reads "average 76mpg"
is there anybody here who believes that is possible as well?

They're not gimmicks. They're just an estimate of the fuel economy.
The brim-brim method gives more reliable results. Any vehicle can achieve an instananeous reading of 76mpg. Driving down a hill with zero throttle should provide infinite mpg.

i drive the 2.0 hdi 90bhp

on a drive between southampton and dover i got 74.4 average mpg

most weeks i get 68.5 mpg average whilst driving around for work, i am a very gentle driver though.

If you want higher mpg & lower running costs head for 2 wheels

What I get hooning about in my Mondeo. Mixture of city and SC A road driving.

I'm still pleased with my 70MPG on a 1986 Citroen BX 1.7D (no turbo), on a run on the motoways at 70MPH. It had no additives, and was verified by using the full to full method. This was when it was 11 years old and with 120K on the clock!

Whilst not as high as some others, I drove to Birmingham on saturday morning. I was so please with the results I even took a photo of it! (normally average 25-27 mpg!)

I often read about millers diesel power sport being a good diesel additive.

I've been using this stuff for about the last 15 months and 17,000 miles.
Same weather conditions, same trip, same driving habits, same diesel pump and the same garage I measure (brim to brim calculation, I know my OBC is inaccurate) a 5% to 7% improvement in MPG using it. It takes 2 to 3 tank fuls to get up to the 5-7% level. If I stop using the additive it drops back down again over 2 tanks. I've started and stopped using it 3 times to test this effect and now I'm totally convinced it makes a difference and don't fill up without it any more. Anyone's standard diesel will do as the fuel.
Along with cleaning additives and lubricants additives like this improve the Cetane number (a measure of how well the fuel burns) by 4 points. In standard diesel which must be at minimum 51 to meet EN590 this boost it to at least 55 (higher is of no further benefit). Since the actual Cetane number of fuels does vary during the year and by refinery and even fuel batch "standard" diesel can often have a higher than 51 Cetane rating anyway which along with all the other variables affecting fuel consumption can make measuring the improvement difficult. On a 45mpg car 5% improvement is an extra 2.25mpg.
On a 7.8mpg articulated lorry your looking at an improvement up to 8.19mpg. Moreover as you travel from one part of Europe to another you picking up fuel in different places from different refineries and the driving conditions must be varying more than a motorist on their daily commute. No surprise that it would be so much harder to measure an improvement and attribute it to a fuel additive.

This is a good read on additives....
