I must admit that I'm very concern, I have a 99 VX and I'm having the very same issues as some of the VX owner’s, high oil consumption and pinging and lost of power.

I just changes to 92-93 Octane and tried some street legal 102-OC two weeks ago. My VX seem to have the power back with no pinging but I'm still not convinced that all is well, with all the issues I'm having at 75k I'm not sure I want to add modifications.

It seems very clear to me that Isuzu is aware of the problem with the earlier 3.5L. Perhaps we should put together a task force with owners to address the matter legally.
