[AT] Synthetic Oil

[Mike M]

I'll add this, I had a Massey Ferguson 255 that was very hard to start 
in cold weather. Switched to Rotella T6 full synthetic, and it gave me 
an extra 10-15 degrees of leeway before I had to plug it in.

I've never been a fan of oil change intervals that are that extended and I am certainly not a fan of expensive synthetic oil.  But because of that expense I decided to use Blackstone lab's oil analysis reports to ensure that these extended intervals actually were valid.

Next oil change I want to 11K and still within spec.  And so on our way up to 13,000 miles.  Oil was still completely 100% within spec and no metals that would indicate excessive wear.  I stopped there but I could probably could change at 15K.
