AMSOIL SYNTHETIC LUBRICANTS. ENGINE OILS,TRANS.FLUIDS,2CYCLE OILS, GREASE, GEAR LUBES, FILTERS, ETC.. CONVENTIONAL MOTOR OIL COMPANIES RECOMMEND 3000 MILE OIL CHANGES AMSOIL RECOMMENDS 25000 MILE OIL CHANGES. CAN USE IN AIRCRAFT ENGINES ALSO.
 
I use amsoil in EVERYTHING. Engines, trasnsmissions, rearends, shocks. in all my vehicles. I am very happy with it. There tech support is excellent. If you are interested in whether the oil will work in aircraft engines I would call their tech support line and they are very well informed.

I've heard that before also but one reason to change oil is to get contamanants out, there is carbon and all kinds of stuff an oil filter doesn't filter. The only way to keep them from recirculating through the engine is to change the oil. It's good oil but I would still change it regularly.
 
We had an Amsoil rep come to SCAC month[y meeting a little while back.Amsoil 20w50 syn can be run in aircraft motors and will last twice as long in between oil changes.
 
I haven't seen where Amsoil was approved by any aircraft engine manufacturer. Ask them if their oil contains LW16702 that is required by a Lycoming service directive. Most aircraft engine manufacturers prefer mineral oil or semi-synthetic but not synthetic for piston engines.
The biggest reason for for frequent oil changes is to remove the bits of metal that is suspended in the oil and to remove the acid that builds up in piston engines. Oil filters don't remove those as well as a good oil change.
The old detergent oils had metals in the oil that helped in cleaning the engine but they haven't been approved in aircraft for decades because the metals left an ash ember that caused pre-ignition. That is why the oil needs to be ashless. Ashless just means no metal is in the oil.
When picking a non approved aircraft oil for an aircraft engine make sure it is an ashless or non-detergent mineral based oil. If you have a Lycoming you can get the LW16702 anti-scuff additive at Aircraft Spruce for about $25 for a 6 oz. bottle and add that to the oil. I would stay away from pure synthetic only because the people who build those engines say to do so.
 
I use Amsoil in everything I own as well...but I don't own an aircraft engine. Amsoil has a low ash oil forumla for propane and and natural gas fueled engines but I do not think Amsoil gets into to the aircraft market at all....officially. Now automotive and marine engines...you betcha...Amsoil is proably as good as anybody's in those categories.



PRODUCT DESCRIPTION
AMSOIL Synthetic Natural Gas Engine Oil is chemically formulated to deliver unsurpassed protection for natural gas engines. Natural Gas Engine Oil has a low-ash formula with highly effective rust and corrosion inhibitors. It circulates quickly to critical engine components for fast, easy cold-weather engine start-ups and has a very low volatility to remain stable in hot engine conditions. AMSOIL Natural Gas Engine Oil resists the effects of high temperature oxidation much longer than petroleum oils.AMSOIL Synthetic Natural Gas Engine Oil (ANG)

As a Dealer of Amsoil Products for over 10 years, I can tell you that Amsoil does not need the LW16702 additive because it already prevents scuffing. Amsoil also clings to internal engine parts much longer than mineral oils during storage and prevents rust and corrosion. There is no other oil that protects an engine as good as Amsoil. The 20W-50
Racing oil is a good oil to use in aircraft engines as well as the SAE 60 Racing Oil.
Years ago, Amsoil did market a oil specificaly for piston aircraft engines. There was not enough sales of the oil to make it proffitable because of the cost of liability insurance the company had to carry for a aircraft oil.
The best way to know when to change the oil is to sample the oil. :lol:
 
Aircraft oil is made to a different specification that auto oil. All of this is explained in this Shell oil publication:

Amsoil is not the answer for every engine, at least not for mine. I have a car that uses oil with any synthetic. I switched back to regular oil years ago in it and the consumption went down to nil.

I still use Amsoil in the diff, but I switched the trans back also because of problems.

Personally I don't see anything wrong with Amsoil in an aircraft engine. My point is that it is not approved by the manufacturers and cannot be used in certified aircraft engines. Airboats should be no problem. I would use it except for the cost. $7 to $10 per quart is a lot of money.

The reason we have frequent oil changes in aircraft is to remove the suspended metal and the acid that forms in the crankcase. Filters just are not enough. Synthetics last much longer and don't break down as quickly as mineral oil. However, we change the mineral oil long before it breaks down too. A 10 quart sump can get pretty costly in a short time. The oil that is approved, tested and certified for aircraft costs half as much. So, why not use it?

The synthetics were used in the jets I flew because of their excellent lubricating properties. We sure didn't use mineral oil in those turbines. I wouldn't hesitate to use Amsoil Racing oil in my airboat if I could buy it for $2 -$3 a quart.
 
Has anyone tried a bypass oil filter? I have one on my truck and dont have any problems with it. It is a 2 micron filter and will take out anything harmful. That way you could extend the oil changes without fear of damage to the engine because of metal particles.

Hey guys bypass or nor you cannot remove the suspended crap,, carbon is .6 microns why do you think your oil turns black.

Exactly!!! I change the oil in my boat not because it gets worn out but rather to get the stuff out that the filter doesn't stop. The filter doesn't remove the carbon or acid.
 
Full synthetic oil is great for many things;but, it is a poor solvent. Aviation synthetic oil is half and half. Since aircraft engines use leaded fuel an oil that acts as a solvent should be used to keep the rings/pistons clean.
 
harvey,
not being argumentative but wouldn't that mean for the GPU aircraft conversation's that don't run AC fuel (like mine) but rather 93 octane pump gas wouldn't a regular synthetic for that application work better y what you just said ?
 
Goldhunter

I think you would be right. If you don't have lead or a lead substitute to build up---you wouldn't need a solvent. But, it would scare the life out of me to run unleaded fuel in a gpu. (I scare easily sometimes, ha ha) JMO I would think the gpu would need lead---even if it didn't require the higher octane of 100LL. ???

I'm no expert. (OK, so everybody has that figured out) I do love Amsoil and use it in my other engines and diff's. I had planned on putting it in my 540 till I read what Paul Royko (the Shell aviation guru) said about it. I know he's selling "Shell" oil.

I think I'm gonna stick with the Aeroshell and 100LL. When I know my engine is absoutely broken in I may switch to synthetic aviation oil which is half and half or use "AV Blend" (av blend will be another subject---but everyone will agree about the girl on their sticker) :lol:
 
thanks harvey

I have only run on tank of AV fuel I my old boat after that it has been pump gas anything under 93 octane it runs fine but will not shut off so I stayed with the 93 pump gas. the oil thing has always been confusing especially with all the "sales pitches" you get when trying to under stand what will work .
