Why couldn't someone just use vegetable oil - kinda like using biodiesel in a truck? Oil is oil for bar lube, right?

Those of you going thru bars, do you file the rails periodically? do you turn the bar over periodically? do you grease the tip?Arer you using rim sprockets?Do you file the drivers after you throw a chain?
Stihl, and all the other brands, don't make their oil, refineries do on contract to their specs. If the Stihl oil is that much more expensive I'd believe they are adding things their competitors aren't.
I've seen lots of posts where it's stated that all bar oil is the same and that it's just refinery junk... So I asked the question of Stihl... "why is your bar oil so special (expensive)" and here's what they say (paraphrased).Stihl bar oil is Napthetic based, and most other bar oils are typically Parafinic (meaning wax based). There are only 3 refineries in the US that produce Napthetic base oil. Only One produces Stihl bar oil - Omni. Omni offers a closed system meaning no other products flow through this line except Stihl. The napthetic base Stihl uses is a virgin base and is not re-refined or recycled oils since these types will always contain suspended contaminants. They also use twice as much paratac, (sticky) as anyone else. Paratac is the most expensive additive in bar oil which is one of the reasons Stihl more expensive.Parafinic means wax based, so it gets thin when hot, thick when cold. Temperature does not have the same marked effect on napthetic oil while giving them a much broader operating range (bar/chain temperature is part of this) Stihl is virgin oil base - and the other have up to 10% junk because they don't use a dedicated line like stihl does. Not sure it make for a significantly better bar oil, but Stihl thinks it is...If anyone is interested in a good paper on basic oil types, napthenic, parraffinc etc... etc..http://www.pdhengineer.com/Course%20...0Additives.pdfOther:Stihl's choice of napthenic base seems be based on not requiring the inclusion of additives to reduce the pour point - just virgin napthenic Base and Paratec. They believe it works better across the temperature ranges of bar/chain needs, and that their winter grade is only required at temperatures less than 20F, if that's a valid data point in this discussion.Whether Stihl bar oil works better than another brand or other base chemistry will always be debated , but the single point packager (distribution costs) and limited USA refiners definitely makes the oil more expensive to them, and to us. Obviously they think it's better than brand -x, but..
Al your memory is too good! The two pennies taped to the camels is an interesting tidbit.
My friend who I mentioned above, the one who wears out bars and chains when using Poulan oil, well, he figured out why. He went back to Stihl and hasn't had a problem.
...As of yesterday, Husqvarna bar oil is now $14.95 a jug, if you were to buy singles!!!
Two things always go past my mind on these bar oil discussions;1. Guys don't trust the used car oil to work in their $200 saw with a $20 oil pump when they have just taken it from a $15,000 car with a $200 oil pump. Anyone that thinks the tollerance in a saw oil pump is tighter than a vehicle oil pump is just plain wrong.2. I bet half of you that say " I don't want that suspended metal from used motor oil in on my bar/chain", file your chain on the bar. Talk about metal filings!
