Advance has techion extra on sale for $5 a gallon. My favorite Delo is up to almost $8 at Walmart/Sams. What are your thoughts on the Castrol product? How does it compare to Delo/1300 for Ag use?
I say go for it, I ran it as the rinse oil for ARx in a 7.3 for 3600 miles and was pleasantly surprised at the smoothness and durability of this oil, should be perfect for an ag oil.
