Is it M.o.t time ?
Are you using too much fuel ?
Does your exhaust smell of bad eggs or is puffing out black smoke ?
You've checked your car over as much as you can, but one aspect of a car which cannot be tested by most home mechanic's, is the exhaust emissions.
Our 4 gas exhaust analyser allows us to evaluate the performance of not only the engine, but of the expensive catalytic converter. Any problems outlined using the gas analyser will ensure your engine runs at maximum efficiency, saving you money on expensive petrol and keeping the engine and exhaust in a clean condition, not to mention helping you do your bit for the environment and leading to a pass certificate at your next m.o.t.
We can also supply a full printout of the exhaust emissions before and after any remedial work to keep for your records. A useful addition to your service record when you eventually sell or pass on your vehicle.
