Oil Type Rotax 582

[Olle1975]

Hello!

I've used the search-function but I can't find a thread about your using of oil in rotax 582.
I've asked this question in a german forum too and there are many different views of oil types
(mineral, sythetik, fullsynthetik) for the 582. Which oil do you use and how long did you use it,
what are your experience of that oil with regard to reliability, condition pistons after 100hrs etc.

Olaf,
I'm currently using full synthetic Amsoil HP Marine 2-Stroke Oil. It probably isn't available in your area, but I'm sure there's a similar product. It works great for me with little carbon build-up and no ring sticking over 110 hours. The only problem with full synthetics is they don't provide much protection for storage, so you need to fog your engine if you don't fly often (like the long winter).

Here's a link: http://www.amsoil.com/shop/by-product/motor-oil/2-stroke/hp-marine-synthetic-2-stroke-oil/

My 582 no longer stops more than 2-3 weeks and I use full-synthetik too, but I don't have a long experience. How do you fog your engine?

To start with, after each flight I always plug the exhaust with a rubber ball and cover the air filter to keep the engine from "breathing" humid air. Then if it will be a month or more before my next flight, I fog. This period of time may vary based on your judgement about the humidity level in your hangar.

I use an aerosol can of fogging oil with the long plastic tube. If you can put a little bend in the end of the tube it can help direct the flow. I open the throttle fully, extend the tube through the carburetor and spray into the crankcase with the goal of coating the rod bearings on the crank. Then I pull a spark plug on each cylinder and spray around the piston circumference to try to hit the walls and ring area. Rotate the engine one cycle and try to leave it with the rotary valve blocking both cylinders.

If you have a dessicant type spark plug, it might help, but I've never done that.

I hope that helps.

Redline Racing. Best stuff on the planet. Period.

dessicant type spark plug

What is this?


Redline Racing

Is very expensive, isn't it? Is it fullsynthetic?

Does anybody use the "conservation process", pull choke before stop the engine like the rotax manual?

Anybody checked his pistons and rings by using the mineral-synthtic or fullsynthetic oil - condition?

[mtgsxr]

expensive but cheeper than an engine rebuild. Its synth. with caster. I have been a 2-stroke mechanic for 20+ years. best stuff I have found. But they will tell you not to run in aircraft, but best oil available for rotax, Polaris, artic cat, & Yamaha snowmobiles... lol they don't want the liability hahaha good stuff... you should also be running Evans coolant.

I've been thru this before in this forum but I'll say it again in case some missed it. I owned a CGS Hawk for 15 years with a Rotax 503. I ran Amsoil Dominator racing oil. It's a little pricey and probably overkill but it served me well. I sold it with the new owner understanding that the engine was high time but still ran as good as ever. He flew it for a while before deciding on having it rebuilt, not because of any problems but for peace of mind. The engine was bought new in 1995 with well over 600 hours. All internal parts we as they came from Rotax in 1995. The Hobbs had worked intermittently for a couple of years before I finally replaced it so who knows exactly how many hours it actually had. The seals had never been replaced and it had never been decarboned. A Rotax service center mechanic said all was within spec and looked like a 150 hour engine on the inside. The crank was perfect and was reused. I run Amsoil in my 912 Rotax, my Ford F150 4X4, my 150 Mercury outboard and chain saws, leaf blower, weed eater and probably some other stuff I don't remember. I'm an Amsoil believer and I don't see how any oil could do any better . James Thomas

One example of dessicant plugs:

For a 582 you'd want to get the 14mm size of dehydrator plugs:

@ jrthomas:

Thanks for your reply, how often do you fly with this engine, every week or do you have had long breaks about a few weeks or months?
I can't find a translation about hobbs?

@ Av8r-Sed:

Thanks for the example, I never seen like this before.....

Know we are 4 pilots, whitch fly synthetic oil in our two-stroke engine, it's surprised because in germany many pilots use mineral oil because of "better" conservation. I think, during long breaks mineral oil is better for conservation than synthetic oil, but during fly and for clean pistons and rings, synthetic oil is the better way. Anybody agree?

Does anybody use the "conservation process", pull choke before stop the engine like the rotax manual?

I use this oil:

Hey Olaf. I sold the Hawk, I think, in the summer of 2011. I flew it pretty often but usually for just an hour or so at a time. I too have always heard that petro based oil was better than synthetic at protecting during extended shut down. I'm not so sure if it's really a problem. My bass boat sits for months at a time. The outboard is a 150 HP Mercury outboard which is a V6 2 stroke and it's oil injected. I've owned outboard bass boats for 30 plus years and have never experienced any internal engine problems so I don't believe internal corrosion is much of a problem. Amsoil is good but it's the only synthetic I've had any personal experience with. I'm sure there are other synthetics that are also very good. James Thomas

Mineral oil is better at holding dirt in suspension (not an issue with two cycle engines) and sticking to parts (pistons etc) during extended periods of storage. Synthetic oil has higher shear strength (less metal wear) and can handle higher temperatures. Best seems to be a 50/50 mix of each.

Hobbs ok, my one is called VDO ;)

[mr bill]

VDO and Hobbs are the manufacturers.

Of course, this was such a joke ;)

Been using AMSOIL for close to 30 years now in heavy equipment, trucks, snowmobiles, Jet skis, motorcycles etc. Never had any issues. Far superior than mineral based oils. When engines were torn down for rebuild there was little to no wear on critical engine components and no sludge buildup. I use amsoil 2 stroke Dominator @ 100:1. I would not be concerned about preservation unless it sits for more than a year. It's expensive but it is the best and it will save you money in the long run with better performance and extended engine life. Remember that synthetic oil is the only oil that can be used in Jet engines.
