I would say yes, do not tow at that high of an rpm for very long, the 1.3's will take nine grand all day long(so i've heard) the 1.6 maybe six or sixty five hundered rpms once and a while under a load, but the 1.8's are not that common for most of us but if it has a longer stroke than a 1.6 I think that sixty five hundered towing is to many r's, just my gut feeling.
