I visited Scott at warpspeedperformance, based in Kilbirnie and had the treatment done today at around 1pm, took a little over an hour and a half, the actual process is around an hour, but obviously we were discussing the process and then of course set up time.

The diesel version is different from the petrol version, ( Ie - they are totally different machines )

The diesel version has an inbuilt tank with a 50/50 mix of the treatment and diesel fuel

Once everything was all connected up through my fuel pump and the feed to the tank was shut off, the process began. The car ran for 20 mins while the mixture ran through the system doing its thing, then a 20 minute "soaking" process during which time the mix was allowed to soak through the fuel system. Then it was another 20 minute session as per the first.

The revs were picked up to around 4k revs towards the end and there was certainly traces of black smoke ( not as much as I expected though )

I spoke to Scott about it and he explained that its still relatively new here, but has been in Canada for around 15 years. The Canadian government has been involved at some point and a lot of it is down to the drive for a cleaner environment. Subaru also use this process in Canada seemingly and recommend its done on a yearly basis to help keep down emmissions.

What have I achieved?

Scientifically speaking? We will never know I guess and no doubt it'll go back n forth for some time to come.

I do know that since I've cleaned my EGR I'm a lot happier and I'm sure its helped some.
I've also switched to running a couple of tanks of Shell V power through her and she did seems a little livelier for sure and mpg "seems" to have improved so far.

The Terraclean today, I'm confident it has helped clean through the system and will reduce emmissions ( Its certianly not going to make them worse )
On the way home after a few runs, during which it did expell some black smoke, which I never experience, it cleaned up back to normal.
Seat of the pants driving to me, says it "feels" a little livelier again and more responsive / eager through the gears, but it is only a feeling

As the car sat idling then at 4k revs for some time. obviously mpg went right down. On the way back home through town, some motorway driving and being gentle she quite quickly started to rise on the mpg display.
Personally, I think that mpg may improve from before the treatment, but cannot say for definite at this time and will be monitoring where it goes over the coming days and weeks.

I'm £65 lighter and still happier that I feel as I may have achieved something positive out of this..............I'll report back as and when

 

Hi Jim, any updates on how things are going with the treatment?

 

Hey Delta,
yeah everythings fine at the moment, thanks.

It's really hard to actually quantify any precise figures as I'm hardly doing any mileage at the moment unfortunately.

All I can say for sure is, it "feels" a little more responsive and the mpg, again "seems" better.

To be honest I really need to run another couple of tankfuls through before I could make any kind of statement based on anything other than seat of the pants driving, age and experience at present.

Its all positive as far as I'm concerned to date and I'm still happy I got it done.

I will try and come back to this post in the coming days / weeks / months as required and update for all.

Good to see you again Delta, I haven't seen you in a while either because I've not bee here or you've not, or we've been passing like ships in the night

 

UPDATE>>>>>

Ok, so having filled my tank with Shell V power and running it through after the Terraclean treatment, I believe I'm starting to see fairly significant mpg improvements ( albeit its early days )
I will return here and post updates as and when I've completed a full tank and also further fill ups moving forward, for those that may be interested.


As previously stated the absolute best mpg I ever actually attained was approx 695 miles
This was ALL motorway and I was hypermiling to try and achieve the best results possible.

This current tankful of fuel, has been a mix of approx 60% city driving with 40% dual carriageway / motorway thrown in.
Although I'm trying to see what is the best mpg I can get, my boot is crammed full of workgear including files / boxes / jackets / hard hats & boots etc as it always has been.
I'm driving carefully and to the limits, no harsh revving, perhaps one slight burst of speed for a little while

The first results are shown below.
The fuel gauge although it cannot be seen has not moved from full at this point.

Distance travelled 76.6 miles
DTE ( Distance to Empty ) 655 miles
Instant MPG - 44.7mpg






Further through the tank of fuel ( still no pic of the fuel gauge - sorry, but at around halfway between full and 3/4 )

Distance travelled 130.6 miles
DTE ( Distance to Empty ) 645 miles
Instant MPG - 48.6mpg







Having eventually learned, the fuel gauge can be clearly seen in these pics and this is where I'm at to date.
The fuel shows clearly that its well above the halfway mark. Usually I can predict around 240 miles - perhaps 280 at halfway position!

Distance travelled 335.9 miles
DTE ( Distance to Empty ) 455 miles
Instant MPG - 51.2mpg






Incidentally, the lifetime mpg counter has been at 36.6 mpg for as long as I can remember, and has since started to climb, currently at 37.1mpg.
From experience ( unless reset ) this will be a very slow n steady climb if there's a continuing upwards trend.....we'll see.

If, and I know it is If I can achieve anywhere near the targeted 790 miles range + whatever is left in the tank it will be the best results achieved over 5 years of ownership AND through a mix of motorway and city driving, not just motorway miles( I'll try and be as accurate as I can with the mix when I post of course )


In the meantime, I've started a fuelly account to try and cross refer my findings
I'll post again when I have more info.

 

UPDATE TODAY 14.08.2012 >>>>>>>>>>>>>>

History first
I used to get decent mileage but then I travelled mostly motorway miles. The best I ever achieved was one day when I had a particularly long run ( approx. 700 miles to cover in one day ) This was with me 6’3” 17 stone + a workmate at 6’7” 19 stone,work gear and a boot crammed full of work related items.
I managed 695 miles covered with 40 approx left in the tank + reserve fuel meant I could have got about 850 miles at the 52.2mpg rate had I run her dry.
Incidentally when I refuelled the DIS told me to expect a 915 mile range if I travelled in the same manner going forward.
915divided by 52.2mpg = 17.6 gallons so it all seems to work out fine!

Recently
My mpg is shot to bits, I travel a mix of city and motorway now, probably 60/40 or thereabouts, maybe even a little more city stop start than that even. The car doesn’t always get up to temp and the instant mpg usually hovers around the mid 30’s range, high 30’s to low 40’s if I’m lucky on motorway jaunts.
The average for the lifetime of the car was recently showing36.6mpg.
Based on the fact I usually get around 500 – 550 to a tank + whatever isleft in reserve it kinda works out about right.

Past week or so
As you may know I recently cleaned my EGR valve, switched to Shell V power and had a Terraclean treatment done on the car. I’ve been monitoring my mpg etc ever since and recently started a fuelly account to help with this. My first fuel up showed 36.7 mpg which is scarily close to the average showing on the DIS in my car.

My second fill up I looked even closer and decided to see what I could get out of her and if the steps I took had any effect. I topped her off with Shell V power and reset the instant trip, but left the lifetime trip meter as is at 36.6mpg

Over the course of the full tank I probably did a mix of 75% motorway and 25% stop start town driving. I was careful, not exactly hypermiling as the boot was still crammed full, the AC was on and the drivers window open slightly as I am a smoker.

I managed to get 750.2 miles on a full tank and this left zero miles in the DIS so I was essentially on reserves at that point.

I refuelled almost exactly the same as the last fill up at £104.01 for 70.80litres of Shell V power diesel. On the basis that my instant mpg had seen 52.2mpg but settled at 51.2mpg and the the fill up showed me that 9.2 litres (2.03 gallons ) remained in reserve, meant if I had run her dry I was looking at an 854 mile range….not bad!

This turnaround in a week or so is impressive, at least for me

From past experience the car’s computer slowly builds mpg when driven sensibly and economically but reduces it drastically when the lead foot appears. 5 years of ownership has taught me once its way down at the kind of levels I mentioned earlier it takes a long time, lots of regular motorway miles and very economic driving to get the upward trend back on track

The only part I don’t understand is the DIS after refuelling showed a DTE of 715 miles?
I was sure this was based on the level of fill x the instant mpg which would have meant approx. 910 mile range NOT the 715 miles as indicated.

Click this bar to view the original image of 800x406px and 88KB.

Anyhow in the matter of less than a week my mpg isup from 36.6mpg to 42.4 according to my fuelly account, even though my instant trip on the DIS shows 51.2 and the average for the lifetime of the car is now at 37.1mpg

This shows a huge improvement for me as far as I'm concerned and I further believe that if I can continue the trend and drive enconomically I can achieve even better results.

 

Update - so my mpg is falling back down to lower levels, albeit higher than they were before.

I'm still using Shell V Power to fill up, but the bulk of my driving these days is all stop / start and around town, probably around 90%+ so I guess its to be expected.

Personally, I'm still confident that the process has helped and I could see much better mpg on longer runs.

To put it simply, sit still a win as far as I'm concerned, the car is running great and no issues at 97k miles
