Back in the 1980's MB didn't offer reman nozzles & fuel quality was very poor. ALL of the injectors that we rebuilt got new tips but with the fuel problems they would fail! For example the 1982 cars had a 2yr 24,000mi warranty & most needed injectors durning the warranty period!
EVERY time you buy fuel there is a chance of water being in the fuel. Water in the fuel causes heat & that will cause the injector tips to seize. That is why most trucks & heavy equiptment STILL have water seperators!
