Hello, I currently run a Renault Laguna 1.9TDi and I am having the following challenges shall we say: Something is wrong with the injectors, and I am told I cannot (should not) blend nice-n-cheap veg oil in with the diesel without a conversion costing £ 1,200.00! My good old ZX (250K miles, no major failures), used to eat rather a good amount of Veg oil and never once complained. The Xsara 1.9TD, is this still the ZX engine, does anyone on here use a mixture in them? I am keen to find out before I purchase. Are they as reliable as the ZX was, frankly the Renault is starting to cost me money and it will almost 100K short of the final ZX value (it was sold as a going concern, prob still working!) :-)
