I'm considering purchasing a 2009 VW Jetta TDI with 12k miles. During summer months, the owner used waste oil for fuel. (no separate tank or conversion kit). But we're in the mountains, and it gets brisk even in the summer. Should I walk away altogether? Can I ask a mechanic to specifically check out the fuel injection system? What else should I ask of the mechanic? Thanks.
