I dunno if this has been talked about on here yet but, I am just about to do my oil change and I had to go all over around town to find enough of the Valvoline High Mileage 10w30 that I have used since I got the XJ (it always had valvoline before that) and in talking to a guy I know who works at walmart, found out that the conventional High Mileage Oil has been discontinued, its all full Synthetic or Synthetic blend. my engine dosn't have a lot of kilometers on it (just hit 247k the other day) but it is 21 years old, and has been using the same type of oil for most of its existance. I have heard stories that sometimes if you start running synthetic or even if you change brands that you seals can start leaking, and I also remember a while back reading a thread guys loosing new cams on built OHV motors because the new oil out there dosn't have as much Zinc and some other additives. I remember from that thread that Valvoline High Mileeage was one of the only oils which still had these additives. Anyways, what I am wondering is if anyone has changed over to their blend or full synth and how thats gone for them. I also remember talk about using Shell Rotella T Diesel oil as that still had zinc content. If anyone has switched over to this stuff I'd also like to hear how it went for them. I know I'm going to have to switch over to a new oil for my next change, I just want to avoid having some of my seals go bad.
