Don't forget to grab your $20 rebate on 2.5 Gal of T6! I bought 2 at Fleet Farm for $56 each. $36 after MIR is tough to beat for 5 gallons of any synthetic oil!

The fact Shell Rotella HD is available at Fleet Farm for $57 w/ $10 rebate makes this a very attractive deal.
Currently, there is also a $20 Fleet Farm gift card included for certain purchases above $100. This oil is currently on the list...
I realize this is an older thread, but I thought I would link the technical sheets for the two oils discussed here. The data almost looks like it was copied and pasted, with the brand name being replaced. Only physical property difference is the pour point; -42 vs -43.6
