550 seized up today

Modern xp saw 550/560 especially. Run it on Husky xp 2stroke oil, simples

I'm sure it will be the oregon oil as I said on another post it's been slated by 2 dealers one husky and one stihl. Apparently it's so crap you have to use it at 25:1. I've only ever used husky xp in all my new 560 576 372 395 and never had a pot piston problem.

Trouble is husky will prob want to see the saw and oregon oil stains the internals and they won't repair under warranty unless you use a synthetic oil.

I was at BTS in Needham Market yesterday and was talking to Trevor their engineer, and having trouble with my Huskies sizing asked him for his opinion. He said the same as you, that you should only run the XP saws on husky xp oil and he also recommends running a stronger oil to petrol mix perhaps 30:1 or 40:1

Same here.

On the 441, the stalling on idle will be the low speed adjustment and not hitting high revs is probably the carb being over rich - it will be worth pullig off the muffler and inspecting the piston to make sure it is OK as low compression can also inhibit the saw to make high revs.

Im running my 550 on super unleaded and the highest grade husqy oil just incase I do have any issues. I dont want to give them a chance to question the warranty.

I have heard on the grape vine that the Oregon oil is a bit pants. Think it was on here.

 

In 12 years I have never had any problems with Oregon two stroke oil from any of my 100's of dealers I look after, I ran three Moto X bikes on it for several years with no problems.

 

Don't believe all you hear try it for yourself we have mineral oil for older machines and semi synthetic low smoke oil for modern high revving machines and its dyed red so you can identify straight away.

Oregon have semi synthetic oil and mineral oil the synthetic oil is a 50.1 mix and I've never had any problems with it. All Oregon oils meet and exceed industry standards.

There are 100's of dealers using Oregon oil apparently they must all be wrong then ?
