Hey guys, I'll be joining this side of the forum very soon. I just bought my pregnant wife a '99 100 series to be her "new" grocery getter (and it'll see the Pismo dunes every once in a while). Anyways, I'ved owned a 60 since may of 2000, and am stoked to now be a two cruiser family.
This 100 has a load of miles on it, 192K to be exact. I don't know the service history up to 150K, but after that it was owned by a Toyota technician, and he sold it to the current owner at 185K. I know it's been dealer maintained since 150K. And no, the timing belt (a second time) has not been done. It is first on my list.
However, do you guys think it is too late for me to convert to synthetic fluids. Oil, tranny, transfer, and diffs? The underside of the truck is dry as a bone and does not currently leak. I am of the belief that age will affect the ability to convert to synthetic and the possibility for leaks more than miles. So as of now, I am leaning towards converting all of the fluids to synthetic soon after I pick up the rig (this week). Also, what about using detergents at this high mileage? I'm leaning towards not. Searching, I see a difference of opinion on the tranny. Should I use synthetic at all, and regardless of that, should I drain/refill or do a complete fluid exchange. I don't now when it was last done.
What do you guys think? Do you think I would be taking a risk converting, or am I good to go? If I do convert, I think it will freshen everything up and add that much more longevity to the life of this truck.
