I did some cost comparison strictly using Amazon prices. Also, I'm only looking at 5W40 type synthetic oils as that is the one I've decided to go with (plus that's what I'm using now, specifically Total Motor Oil)

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.....

Mobil 1 is much cheaper if you buy it in 5qt jugs. Usually around $25 for 5qts ($5 per qt).

And if you buy Mobil 1 in Australia, it will only cost you $US75-00 for 5 litres......
