MY DAUGHTER owns a 1985 190E Mercedes-Benz and runs it on 95 octane PULP. Is this suitable? Should she add an LRP additive?
PULP is the best fuel for the W201 190E. It has the required octane for that engine, which would have been developed to run on the old leaded super. The Australian Institute of Petroleum says you should use an additive, but the Merc has an alloy cylinder head with cast-iron valve seat inserts that have probably been hardened. which means you could safely run it without an additive.
