“Excellent customer service from start to finish. Had my 2012 Jaguar XF S 3.0d TerraCleaned last week. I must admit I was very sceptical about the process on a low mileage and well maintained car (full Jag service history). After the TerraClean I went on a long run of about 150 miles, where I noticed my mpg had risen from a normal 42 mpg to around 45 mpg, also the car felt tighter and more responsive to drive. I am a convert! To that end I am getting all my families cars done. I am certain I will make more than my money back on saved fuel costs alone. Thank you!!”.

“I took my Audi A4 estate with approx 171k miles to be terracleaned a couple of weeks ago and the results have been very good! The car is much more responsive and smoother. driving back from north devon to newbury last week in the rain at approx 55mph the average mpg was showing at 56!! on the way down at normal motorway crusing speed it was above 50mpg an increase of at least 3mpg. I will be back!”

“Had my Volvo S60 done six weeks ago and I am well impressed! Acceleration has improved, it runs better and I get 5 to 6 more mpg”.

”My car had the TerraClean treatment yesterday and already I can feel the car performs so much better. The service was 1st class and everyone was very friendly and very helpful. Certainly would recommend”.

“I Had my Range Rover TDV6 sport TerraCleaned by Martin Mathewson Last week. to say i was impressed with the service given is a major understatement. Superb 5* service, fantastic communication and oh yer nearly forgot, my Range Rover now delivers about 7mpg better consumption on a run, up from 29mpg to now 36 mpg ....yes 36 mpg incredible I think you'll agree. Would definitely use the TerraClean service again, as would I use Martin Matthewson Ltd. Superb work guys”.

“My Volvo V50 (56 reg, 2.0D with a RICA remap, and 151K miles under the belt) went in for a TerraClean around 3 months ago, after I saw the treatment advertised. I think it's fair to say my observations since the treatment well and truly mirror that of others on here: immediately noticed an increased general smoothness in the running of the engine....a couple of times I've been in 50mph road works zones for extended periods, and I've accidentally left the car rolling along on cruise control in 5th gear rather than 6th....previously you'd ALWAYS know if the car was in 5th ! Much more eager to rev to redline, much less hesitation in doing so. Definitely a small increase in economy too....just this week I covered 538 miles (predominantly motor way driving at 70mph+) and took 46.5 litres to top it up....I would guestimate a circa 4-6% improvement in economy. A thoroughly worthwhile exercise, I would recommend it to any diesel vehicle owner, and the guys at Basingstoke were great".

”I recommend this to anyone. I had my S60 D5 done and I managed to drive to Scotland and back on a tank of fuel. Totalling 822 miles. Deffo worth the money. I never thought I would be able to fall in love with my car all over again, until I had the TerraClean.

”I had my 2006 Jaguar x-type 2.0 diesel TerraCleaned and noticed the improvements straightaway. I would certainly recommend anyone to have this done, you will not be disappointed”.

”Booked my car in last minute for a TerraClean, Air Con re-gas and diagnostics and they were able to do all 3 for me. Car drives like a dream now. Gained over 30 MPG already and drives so much better and more powerful. Definitely recommend to anyone”.

”I had my Audi A5 3.0 Tdi quattro with a 100k on it TerraCleaned by the Volvo Specialist in Basingstoke, and the service I received was excellent. My car was already very refined and smooth and ran like a dream. I was getting on average between 38-42mpg on any run that I was doing and when driving super efficiently, I could easily get up to 47mpg. After the TerraClean the engine is still as smooth and refined as it was before, but my economy is now between 40-44mpg. On a super efficient drive I had my car up to 49mpg so it is a definite improvement in mpg, and well worth the money I paid. It’s a no brainer really and I would recommend having this done every 50K”.

”Had my car TerraCleaned in Basingstoke this week and immediately I drove away I noticed the car was a lot smoother. After a couple of days the car feels tighter and more efficient all around, the guys at the garage are fantastic and i would recommend this service to anyone having doubts. definitely worth your money”.

”I had my 2003 BMW Compact TerraCleaned a week ago. What a difference, the car runs so much more smoothly and has now got better MPG. Before I had this done the car was hunting on tick over but now it ticks over perfectly. Would definitely recommend having this done to any car”.

”I have a 1.4 diesel 2003 Peugeot 206 and was getting about 620 miles to tank of fuel. Most folk will kill for that I know, BUT after the treatment I now get 710 miles! Or almost 15%.All for £75!! Payback in 7 tanks of fuel, after that all savings, just brilliant.As a bonus the guys are friendly, knowledgeable and love cars. I know that this sounds like an advert but is not meant to be - its just my experience”.

”I took my 12 year old Volvo S40T to Martin Matthewson Ltd in Basingstoke. I did notice a difference straight away. Idling is smoother and the car seems to drive better. I have a regular drive each week to a couple of places and I have seen a 9% improvement in mpg.I'm very pleased and would highly recommend TerraClean”.

“Mercedes CLK 270 CDI AMG - The car has great power and torque in its original state. There were some performance issues dues to Inlet Manifold Swirl Flap problems which have now been remedied. I had heard about TerraClean, and being local to the area I was able to contact Martin on Thursday and had the car TerraCleaned on Friday. The reviews detailed the gains and improvements to be seen once TerraCleaned. There was an immediate noticeable difference. The car is smoother, runs quieter and on a run to and from Portsmouth I was seeing economies of 53.1 mpg whilst at 75mph (2300 rpm). I will see the return on this investment in no time whatsoever, and highly recommend TerraClean to anyone. I will definitely be having it done again after my next service”.

“I took my Dodge Nitro for TerraClean and what can I say, better acceleration, mpg increased and more power. Would highly recommend”.

”I purchased a Vauxhall Zafira 1.9 tdi back in December last year. It was giving me an average of 39.9mpg. I had the ECU re-mapped which gave me an increase of about 7pgm, then in February I contacted Martin to have a TerraClean treatment done as the car is slightly higher than normal millage for it's year. After the TerraClean I have an extra increase of 4-6mpg, and a smoother quieter engine. I would definitely recommend the TerraClean treatment and Martin for his knowledge and service. 5 stars”.

”Wow amazing customer service. After only having the car for 15 minutes in the workshop, the problem was diagnosed. Phoned me and discussed the problem and price which was very reasonable. Had the car TerraCleaned as well, car is driving much better than it ever has since I have owned it. Big thank you and will definately be a returning customer”.

”Had service carried out on Volvo V50 and also had TerraClean. Got back from Derbyshire last week and found to be very satisfactory with a slight improvement on mileage and noise level lower. Well worth doing. Have told friends about this service”.

“Lack of power for a 2.4 turbo and knocking front suspension. Martin slotted me in at short notice, replaced the anti-roll link bushes and gave the engine and systems a TerraClean. More power, smooth acceleration throughout the range and better mpg. Feels like a new car! Thanks Martin”.

"DIY Aggregates had our lorry TerraCleaned, and it's made a big difference, go for it!!!”

”I had my Picasso 2.0 HDi diesel TerraCleaned as it tended to fail its MOT on emissions. Also I noticed the fuel consumption was gradually deteriorating, which I thought was due to age. However after the treatment it passed the MOT, and better yet I am now getting an extra 5 mpg, It's also stopped smoking on hard acceleration - I used to leave a choking black cloud behind! Well worth doing, thanks Martin and guys”.

”I had my 08' VW Passat with 88k miles on the clock done with Martin a couple of month's ago and gave it this time to evaluate MPG and running feedback. I do a 60 mile round trip to work and back, mostly motorway and was getting up to 54 MPG in my 2.0 TDI. After the TerraClean I am glad to report a significant increase of up to 59MPG, and want to break into 60 if I adapt my driving style! The car is also more responsive and quieter when idling so have no hesitation to recommend this to others. As I will be keeping my car for 4 years, I feel this is a great investment and will no doubt do it again once I clock up more miles. Thanks again!”

"After having my diesel Mondeo TerraCleaned at Martin's I've noticed an increase of 6 mpg from 36 to 42 and I only usually do short but frequent journeys around town, so I'm very impressed. Without doing motorway journeys I can still get 600 miles from a full tank. Thanks Martin and team for a polite, professional service."

“I had my BMW 325i TerraCleaned by Martin last month following the positive experience on my brother's Vauxhall Astra. My BMW had done 128,500 miles and since then I've noticed a 3-4MPG increase around town, previously 19-22 MPG, now more 21-24. In addition to that the engine feels like it's working more efficiently where as before it felt a bit "heavy". The MOT came quite soon after the TerraClean and the emission figures were impressive to say the least: 2012CO: 0.011HC: 272013CO: 0.004HC: 13 Even my MOT tester had a surprised look as he has never seen figures that low! To top it off both Martin and Lee are very helpful people. Thanks again gentlemen!”

”Last month I had my 130K 2.2 TDCI Ford Mondeo TerraCleaned by Martin and I have been amazed by the results. Martin suggested it might be beneficial to have it done to improve performance and MPG and as my car was in for its regular service anyway I decided to go ahead. I used to get an average of between 45 and 46 MPG on my commute to work (85 Miles round trip). I’m now getting an average of between 55 and 58 MPG and regularly get well over 600 miles out of a tank. Performance has also improved with smoother idling and much better acceleration. It has been worth every penny. Thank you to Martin and his team for the excellent service and advice as usual”.

”I recently had my brother's Vauxhall Astra 1.6 16v with 88,000 miles on the clock TerraCleaned by Martin. Even after finishing the process and with Martin reconnecting the fuel line back to the car to start it up I noticed the engine idled quieter. From the moment leaving I noticed the throttle response was much more responsive and the engine is far more free revving. My brothers words were "The throttle is now instant response where as before it was muted" MPG wise he is still gauging as he hasn't done a brim to brim calculation yet, but that aside it has made driving the car that much better now. To top it off both Lee and Martin are very helpful and knowledgeable people. Many thanks!”

”My 90k miles diesel Volvo S60 was feeling a bit tired and sluggish and dropping MPG. Had this done at Martin Matthewson’s and is now like a brand new car. Engine revs up noticeably freely, power is restored and MPG instantly better - less gas seems to be needed to keep her moving. Well worth the money”.

”My 120K mileage, Mercedes CLK 270CDI was TerraClean 'fettled' by Martin Matthewson, a couple of weeks ago and the results have been very noticeable. Faster pick up at any point in the rev range. The torque 'punch' more immediate and much improved at the optimum point on the torque curve of 2300 rpm., The whole engine seems to be 'breathing' easier and I'm also noticing that I now 'lift off' earlier on the 'loud' pedal as well as the engine 'spins' along much more freely, easier on the ear as well! All these improvements have had a significant overall effect upon the resulting mpg., which I find has improved by between 8-10 mpg throughout, and more'so on a long run when the engine is up to optimum temperature.As the saying goes...GO FOR IT!”

”I've just had my Volvo v40 TerraCleaned and I've noticed a vast improvement in MPG, more responsive when pulling away from junctions and when overtaking, it's well worth the money”.

”Had my Volvo V70 diesel done with 148,000 miles on the clock. It feels like it has had a new lease of life - love it!! Thanks”.

"I'm happy to say that after my engine was TerraCleaned there was a huge improvement in the acceleration of the car and the MPG also improved hugely. I particularly noticed that it was more responsive when overtaking, it just seemed to have 'longer legs'."
