[VAC] Re: When towing, is a synthetic oil better?

[Bob Kiger]

I would agree with Jim but with the proviso that the vehicle is new or close to new.  An older engine can actually develop leaks with synthetic because it grew up on coarser conventional oil.  Synthetic is much more capable of penetrating everything including seals.

Cindy,
 Synthetic oil is nearly always better, towing or not. Most folks run
much-extended change intervals, making the cost nearly the same as
conventional oils. In my manual, Dodge recommends synthetic oil in the
rear axle "for heavy-duty towing service".
