Best price per quart:
Mobil 1 5W40: $7.98
Castrol Edge: $8.10
Pennzoil Platinum Euro: $7.18
Motul 8100 X-cess: $6.53 (in bigger bulk about $6.00)
Total: $7.00
Shell Rotella: $5.52
DT-40: $10.99
Now barring any dumb math errors (entirely possible) and maybe missing a better deal somewhere on Amazon (I did this quick)...it looks to me like the Total is a pretty good buy when you buy it 15 quarts at a time. Clearly Rotella is the best buy.
The only comment I have about Rotella is that is says its for diesel engines. Was I picking the wrong one? Little confused here. Some say they work on both engines.
Anyway.....

You want the Shell Rotella T6, and yes it is a diesel oil, but it also works fine in gas engines.
