Rotella diesel oil should never be used in modern cars with catalytic converters and exhaust sensors as zinc/etc damages those components. From what I have read, Diesel oil is OK for our older cars, and the zinc may be beneficial.


My reading also indicates that modern low Zinc oils are OK to use in older cars since they are formulated with different ingredients as a replacement for Zinc.


My opinion, hope this does not start teh great oil/zinc debates again.
