Some of the 1.6TD ("TD" meaning "Turbo Diesel" NO "I")
engines were in cars badged ECO (for economy, I
assume) Diesels.  Their main purpose in life was fuel
economy.  Those engines recieved turbos that focused
on economy rather than more power.  These Jettas were
sold in the early '90s.

The TDI engines weren't introduced until several years
later than your car was built--I don't think there
were any TDI (Turbo Direct Injection) engines until
'96 (not 100% sure).

And, actually, I've read that the VW TDI is one of the
few TDI engines what work good with vegoil use.

Your EDO Diesel will be all the more economical with
vegoil use.
