Good to know, thanks.
Are there any particular brands you do suggest and weight? Like I said I have a 2001 Base with 43K miles and not replaced the IMS. I live in California and we have very mild winters (that is even a stretch, rarely hits freezing, and I actually rarely drive it in the winter, only on trips to the coast).  Appreciate any help on this matter.
