Never knew it was on the market. Do you know the cost per gallon and 5 gallon pail ?

I remember paying about $130/5 gallon jug last year. We will see later today.

That's about $26 per gallon. Slightly high. But have you considered running it your normal time and sending in a sample to see the results ? That's what I would do.

wow.. Rotella T @ TSC is like $60/5gal.

I use Mobil One 15w-40 all the way down to -25*F with no ill effects.High idle in 3 cylinder mode I can have 100*F of coolant temp in 3 minutes.No problem.
