Rotella T6 5W-40 Shortage

[ldoyle]

Just curious , what`s the difference in T-5 and T-6 ? Also between 5-40 and 15-40 ? Which weight would be best in these hot Texas months ?

T5 is synthetic blend vs T6 is full synthetic. I've been running 15w40 T6 in mine for over 200k in North Texas and haven't had any issues. I don't do much heavy towing tho.

5 is a blend while 6 is full synthetic which means little to me.

The weights are more critical, older Diesel engines used 15-40 but some newer ones (powerstroke) require the 5-40 dues to clearances in engine components. and the wrong oil will void your warranty

I have a 6.7 and manual says to use 15-40 in hot areas.

Looks like they flipped the price back to the original $145, glad I snagged up a case when I did.
