    Default Diesel Performance & Fuel

    Many know that I used the Signum to tow the Caravan across France at the end of July. So I thought I would write about my experiences with the Signum and it's performance and economy.

    Here we are at Portsmouth ready to go!!



    Anyway, I filled up with BP ultimate Diesel before I left. This is the first time I had towed with the 3.0 CDTi, as in the past I have used 2 1.9 CDTi 150's, the second with the VXRPC re-map.

    Both 1.9's towed very well indeed, the interesting point being the old black 1.9 CDTi (VXRPC Re-map) was 188bhp and 301lb/ft, compared to the 3.0 CDTi with 184bhp and 295lb/ft.

    I would have thought they would tow very much the same way, but the 3.0 without a doubt out performs my old car in terms of towing capabilities due to using more natural torque of the V6 rather than the mapped 1.9, anyway I digress from the original thread!!

    We were acheiving 32.8mpg average towing down to Portsmouth and the car was happy in 6th gear on cruise at 60-65mph.

    In southern Normandy, we had to fill up with local diesel, within 20 miles, the mpg had dropped by 7mpg and the car would not pull very well in 6th. Unfortunatley I had to put up with it for a good while.

    Flash to two weeks later on the return journey, I pulled into a Shell station and they had V-Power Diesel, so some of that is the order of the day. So once filled up, within 50 miles, mpg was back to around 30-31mpg and it pulled like a train in 6th.

    Once home, I had a pretty much emtpy tank, so half filled up locally with V Power Diesel, added Forte diesel treatment and gave her a good run. Full throttle from time to time to ensure the injectors opened to their max and cleaned out the system. This also for sure has made the engine run smoother and has much less diesel knock on tick over.

    Then filled up again (Shell V-Power Diesel), did 553 miles on one tank and the average mpg has risen to an average of 40.1mpg, but calculated to 47.8mpg for the tank full. I admit I ran this economically.

    I was always doubtfull about whether BP Ultimate or Shell V Power Diesel would really make that much difference, but towing does show the difference rather than using the car on it's own.

    But my trip to France towing sure did show that decent fuel does make all the differnce.

    As a towcar, I have found that the Signum with it's very short overhang on the rear, is in my opinion far better than the Vectra Hatch, not that the Vectra hatch is bad, far from it, it is a fine towcar and I would for sure use one again but this along with the sports suspension and the 235 tyres mde the car feel as steady as a truck!!!

    Default Great Engine

    I had my doubts when I went from the 2.0dti Vectra Estate to the 3.0 v6 Estate but have no regrets at all. The V6 allowes for effortless driving but can be fun if pushed. I use mine to pull the display unit below. It is about 1300KG and the Vectra takes it all in it's stride.

    You know what, it looks a bluddy good combination that, not too much weight on the ball making it look all nose up.

    The rear overhang (or lack of it) really makes the Signum look like a superb towcar, before you consider the power!

    Saw one the other day and it was towing a twin axle caravan of some description, it looked so 'comfortable' with it.

    Isn't foreign fuel a bit weaker than ours in it's rating?

    I've had my 2.2 DTi SRi now for about three weeks, considered bunging in some fuel cleaner but was unsure if it was a good idea as it's only done 40k..

    ...might try a tank of V-Power Diesel and see if that makes any difference.
