It's been about 6 weeks since Kieran and I did the work...
1) The lower revs per mph and lower engine temperature I posted about at the time have persisted. This is A Good Thing.
2) Shifts are smoother now.
3) Mechanical lockup comes in sooner
4) Fuel economy. This is decidely improved. With my regular commuting I was getting 28.3-28.5mpg previously (better than I'd thought). With no change in driving style this immediately jumped to 29.5-29.8mpg. Good start.
However, it seems to have more impact on long journey economy. Over the easter weekend (prior to changing the ATF) I did a run to my parent's house in gloucester from oldham. I arranged everything to give the best possible mpg... filled up the car from warm on the friday morning and drove straight down deserted motorways on the friday afternoon at a constant 70mph all the way. Same back up on the sunday until I stopped to get fuel so as not to "spoil" the result by having additional engine starts or commuting on that tank. That got me 36.6mpg.
A couple of weeks ago I went down to my parent's place again. Also bank holiday weekend, but the friday wasn't off so the motorways were packed. Thus rather than drive down the M6/M5 I went down the A49, with all the stop/start that entailed, plus a few overtaking maneuvers on caravans. Driving back on the sunday was an easy run up the motorway, but I then commuted for a week (presumably around my 29.5-29.8 level as before) before filling up again. The result was 36.4mpg!
Now driving with a stupidly light foot and trying to save fuel as much as possible on my commute (8 miles of NSL steep hills, 4 miles of 30mph in city traffic) I'm getting 33.6mpg.
This is a pretty damn good improvement. I suspect it's a combination of more efficient power transfer in the box and the knock-on effect of lower engine temperature and the increased efficiency due to more mechanical lockup use. I do wonder what the impact on a pod run would be? /Hmmm :inquisiti
Overall, given that the price arranged through the club discount isn't horrific and that this is basically the ONLY SPII/SPIII compatible fluid available along with the increased temperature range and longer life, I can only give this stuff a MASSIVE :thumbsup: :thumbsup: :thumbsup: :thumbsup: :thumbsup:
Do it. You know your car is worth it.
