Engine 'carbon cleaning'
been thinking of getting my local to run one of those Carbon Cleaning things on the car to see if that helps the old MPG (and just generally for longevity, good running order, etc)
anyone had any experience of that, was it worth it, is it just snake oil, etc. I saw it on wheeler dealers and that Ed bloke said it was good, to be fair he seems to know his stuff. or does he just read a script. who knows searched previous posts and seem to be mostly discussing diesel engines, mines a petrol for whatever that's worth thanks in advance Last edited by stuart bowes; Apr 9th, 2021 at 23:30. |

I think they have much more impact on diesel than petrol engines...

I figured that might be the case but I'm trying to think of ways to improve sub-par mpg
even it it might give me like 3 more mpg it's worth it surely 17mpg, average 10.000 miles in a year =588 gallons 20mpg. average 10,000 miles in a year =500 gallons 88 gallons = 400 litres = £480 @ £1.20 per litre that's a brand new set of tyres ===== ignores the fact that soon hopefully it wont just be Urban, so then we might be talking about going from 25 to 28 but the point remains Last edited by stuart bowes; Apr 12th, 2021 at 22:35. |

If you are splitting hairs over 3mpg on a car doing 17mpg currently and MPG is a concern for you.........spending more money on a Carbon Clean is not necessarily the answer here.
That said I have used it on a 1.9TDi T5 Transporter which included taking inlet manifold off and de-coking that the results were a slightly quieter engine and more urgency. I didn't bother with MPG checks as I don't drive the exact same routes every day so any test would have been flawed from the get go, not to mention temperature differences each day, how often did I start stop, etc. Better to maintain decent tyre pressures and make sure brakes are freed off......moderate throttle, etc I don't think this service will benefit a car of that age. More for direct injection stuff with swirl flaps and the like as they are notorious for "gumming" up especially with EGR valves, etc fitted.

i wouldn't bother doing it on a car this age, particularly with it being petrol.

Fair enough thanks, will look for other options then
I already do all the obvious things like tyre pressures, throttle control, not using air con etc. I'm not into hypermiling or anything is just that this particular car should be getting a few more mpg on average from what I've read and I'm trying to work out why rather than just accepting it as a given I don't think my brakes are binding, but I have replaced everything in the last few months so it is all very tight and new just because of pads and discs going back to the correct thicknesses I guess The number 3 was just a mathematical example of how a small improvement can add up to a worthy annual saving Last edited by stuart bowes; Apr 13th, 2021 at 09:00. |
