Must be time for a ported 562.

Yup! He's got a stock 562XP, and I've got a stock 572XP. Not sure which one would benefit more from porting? Seems like I'm in the right crowd to ask! I might have them both nannered one of these days, just can't really have them both gone at once for an extended amount of time, so I'll have to do one, then the other. One of them 395s from this thread will be hitting my door tomorrow I believe, I'll post a pic once I get a bar on it, and before its dirty! Lol!

Vegetable oil will eat through paint, metal and rubber if left long enough.

This.

If it is gummed up it is 'bio' oil, not straight canola/rapeseed. For some reason, manufacturer's like to add tackifiers to their versions of 'bio oil' that usually make things even worse.
I've tried Stihl and Husky versions of the stuff and now I stay clear. I am guessing it minimizes how much oil/fuel ratio is used to be as environmentally friendly as possible. Most vegetable oils will actually act more like a solvent than gum up. It loses it's acidity over time, so I haven't seen it disolve anything just by sitting yet. I still have paint in all my oil tanks.

Rapeseed and Canola(depending on the mixture - you really want straight rapeseed if you can get it) actually flow a little better than most chainsaw petroleum based oils do. This is how it oils the bars better in practice - the flow, not it's oiling properties. It also seems to cool the bar better from my rudimentary testing. The problem with it flowing better is you may run out of oil before fuel goes out in some saws. I haven't ran out of rapeseed before fuel yet, but I have heard it might be possible, but no anecdotal evidence from anyone yet. I usually run any adjustable oiler to max. The only issue is rapeseed oil is difficult to see when you test the oiler. So it may be concerning to some folks since it is harder to tell if they are getting oil due to it's light color. I can tell simply looking at my chain that it's slathered in oil.

Rapeseed biodegrades very quickly in the environment. Like 30-60 days and it's broken down, faster if it's sunny. Petroleum is nearly forever - the bases are manufactured to not break down for as long as possible, after all.

Rapeseed is slightly acidic and it actually has a cleaning function. So if it is gummed up, it isn't rapeseed. I once cut a days worth of very big mature laurel and rhododendron. The front of my chassis was covered in sap. I took some rapeseed on a cloth and cleaned the sap off with it.

I have been using straight rapeseed for 8 years. I've used it in 33cc saws up to heavily ported 205 and 225psi racing saws, and hard working 288xp's and 044's. Never an issue. Never gums up. No bar issues. I do run my saws in Ireland, where the natives literally will complain if the weather tops 68*F, and it rarely freezes. It's basically between 40-65*F nearly all year. So keep that in mind. Though in the coldest conditions, I have seen tests in Canada show it works great - during the hottest of weather, it may not stick enough to the bar if it is big and making a lot of heat.

Look, Ma, no oil marks:

Rapeseed oil is top fuel lubricant in diesel fuel systems from what I read. It burns really nice also.
