Are you going to run them in various sized wood or just one of the big'uns???

for those that care, the fluid capacities are as follows:
7900- 25oz fuel 13.5 oz oil
390- 28oz fuel 16 oz oil
660- 28oz fuel 12.2 oz oil
18# 11.6oz
For stock testing, I only intend to test with 24" bars. Once modded, I'll probably put 32" bars on them and stick them in some of that Oak. If I could quit my day job, I'd do all the testing you want![]()
Wonder why the 660 has a smaller oil capacity?
I always assumed the oil capacity had something to do with fuel usage. I know the 441 has a greater oil capacity than a 440 or 460 as you go longer between refuel/refill of the bar oil. This is just a guess, as I have know idea how the 660 and 390 compare in terms of fuel usage.
I think that may be under utilizing those saws.
From what I under stand, they design it so the gas runs out first. But you shouldn't let the gas run out! LOL
+1... 70cc and 90cc are pretty close in speed until you pull out the long bars or should I say bury the long bars.

So the 390 is better on fuel than the 660.
Another test to throw in the mix for ya Brad:hmm3grin2orange:
LOL, from what I hear, you've never buried the "long bar".
I think that may be under utilizing those saws.
You may be right, but I sure have tried! Is it my fault I have too much bar for the job! LOL
Hmm, too long for the job! That's not what Brad said about your "Long Bar" our West Coast long bar, and your long bar is two totally different things. LOL! 28" is short around here LOL
The newer stihl saws don't pump out enough oil for my taste.
LOL! I usually just run the 25" on the 441 but I have a 32" for those special occasions! I have buried it in oak, maple and pine a few times. I run a 30" on the J-red. Most of the time these bars are overkill in the east. What we give up in length we make up for in hardness of wood.LOL
