Question AMSOIL Synthetic Question

I've been persuaded to give AMSOIL Synthetic a try with my next engine oil change.

AMSOIL offers incredible guarantees for extended mileage use but they are subject to using their oil filters.

Does anyone know if they make an oil filter to fit a K1200 engine? If so, part number or where to get one would be very helpful.

Thanks,
Keir

The Amsoil oil filter # is SMF122. They are painted black. We've run a whole bunch of them in many LT's for a buttload of miles without any problems or paint flaking.

I'm not gonna comment on extended oil changes as that's too much like an oil thread.

Is saying you're not gonna comment constitute a comment?

Thanks Grif.
Not sure about New Braunfels TX, but here in Fredericton, saying you won't comment is definitely a comment .....
BTW -- Can you but the AMSOIL Filter (to fit an LT) pretty much anywhere they sell the oil?

Not too long ago, they changed their filter line up for the BMWs. What used to be SMF122 for the K1200LT, is now EaOM122. Looks identical to me. I've got one of each in the gearage. So I guess it's what is inside that makes the difference - somethang about nanofiber material?!?! Still painted on the outside.

The new filters supposedly allow you go longer between filter changes and trap more bad stuff.

Any dealer that sells the oil can sell you a filter.

I'm using both the amsoil synthoil and the severe gear oil. I have been using it with the BMW filters. Have a couple of the Amsoil filter that I will start using on the next change.

Now, clarify for me if you can.

Is a buttload more or less than a crap-ton? Or am I mixing my fruit here. Maybe I should be asking about a boat-load?? I'm pretty sure that a hella-bunch is less than a boat-load, but not quite sure where buttload fits in. I'm thinking crap-ton is more than any of 'em combined - but I could wrong.

I used the chrome plated one. As far as I know I have not had any problems. I will be doing my oil change soon. I will post the results.

For what it's worth, I was running MOBIL 1 15-50w extended performance synthetic in my '01 LT and decided to try the Amsoil 15-50w synthetic (motorcycle oil) just to see if I could tell any difference.

The difference was instantly noticable, but in a NEGATIVE way. I could hear a LOT more engine noise. Switched back to the Mobil 1 and it stopped. It was amazing. Very noticeable. (Plus the snake oil...er...I mean AMSoil, was a good bit more expensive).

+1 Pastor Jack.

In my 2004 GL1800 I used Mobil 1 for 15,000 miles then tried Amsoil. I could hear much more internal engine/gearbox noise with the Amsoil and the bike seemed a bit sluggish - almost like there was a greater amount of friction.

That's my 2 cents worth.

I believe a buttload is a measure of distance as opposed to weight. Somewhat similar to a lightyear which some (hopefully few) believe is a measure of time...a buttload refers to the number of miles one can ride an LT with a standard seat. A crap-ton is definitely a measure of weight and I believe the National Bureau of Standards maintains a weight with this name as a standard.

Friction: Mobil 1 vs. Amsoil

Did you use motorcycle specific Amsoil and Mobil 1? Were the viscosities the same on both oils? What viscosity was it? Just curious.

Similarly from the suthern vernackular, a "fer piece" is also a measure of distance, while a "hankerin" is a measure of potential energy.

In my case, the viscosities were the same. Both were (15 -50w)
The MOBIL 1 was not motorcycle specific (just fine in the LT) and the AMSOIL was motorcycle specific.

OK... I'm lazy. I know I could look up the info in my owner's manual, but it's much more interesting hearing it from all of you.

I've been doing my own service on my Harleys for years, being a big fan of AMSOIL more recently, so you'll have to bear with my "newbie-ish-ness" (is that a real word???) on the LT. On the Harley, I used AMSOIL for the tranny, motor, and primary every 5K. My understanding with the LT is that fluids need changed at 6K intervals. I'm now at 18K on my used '05 LT and would like to do this myself. What fluids need changed and can the same lubricant be used in all of these? It's interesting that Mobil 1 users noticed more "noise" when switching to AMSOIL. On the Harley, AMSOIL made things much more quiet and smoother. Also, for those of you using Mobil 1, where can I get a filter besides the BMW dealer? Consider me a lemming... if y'all are doing it, then I will too! Thanks much!

I used Mobil 1 that was recommended for wet clutch motorcycle applications (red cap?) and Amsoil MC oil.

My experience exactly with Amsoil.

05 Road Glide, 98", 615/585 sticks, duel 50mm throttle body, 10.8:1, roughly 110/115 HP/Torque, and Amsoil ran it quiet. Mobil was noisy, Amsoil not. I am using Sever Gear Amsoil in my FD and Trany on the LT, 600, 3000, and the upcoming 6000 service.

Guess there is a difference on the LT, and I wont know for another 6000 until my most EXCELLENT Service Manger tells me it is OK, he said 12,000 for a minimum on Synth in the motor.

Are you guys actually running motor oil for 12k in a motorcycle engine??? Or ANY engine???

No way in the world I would do that. No way....and I don't care who told me that.

Let me interpret...

I agree with you and I certainly don't run my oil that far in anything, but I also don't believe that's LAF was saying. I think the recommendation is to hold off on using synthetic in the motor until you reach 12K. Maybe... maybe not. I know that Amsoil claims you can go double the manufacturer's recommendation on oil changes when using their product (in this case, that would be 12K). I have seen independent lab results of used Amsoil out of a Goldwing where the oil was used for twice the mileage recommended by Honda. Very impressive results, but I still wouldn't recommend it. Just my $.02 worth.

Back to my one of my original questions... what fluids should I be changing at 18K?

Uhh, yeah.
I have been using Amsoil in all my cars I have had and the bike also.
In 1998 I bought a brand new VW Jetta with a TDI Diesel motor. I drove it for work and put 29K a year. I used Amsoil and was told to run it around 12-15K miles, drop the filter and replace one quart, then run it to 25K and then do a complete oil and filter change. THat seemed kinda like a LONG time since I was used to the "every 3000" approach. I ran the diesel car to 10K and then pulled a sample of the oil and had it sent off to be analyzed. THe tests came back with a bunch or compounds that I have no idea what they were but the bottom line on the test was that the oil was good for ANOTHER 20-25K miles due to the compounds that were there. That was after 10K already. I had a hard time going that far since I was used to the 3K mile thing so I just had it changed every 10K.
I am still using Amsoil in the bike and two cars and have NO problems with them.

I'm also running the Amsoil 20W50 motorcycle oil (the new MCV version) and the EaOM122 Amsoil motorcycle oil filter for 12,000 miles each for 100,000 miles now. The new MCV version is much improved over the old AMV version Amsoil. I also ran the Mobil 1 motorcycle oil at 6,000 mile intervals, but my LT runs cooler, quieter, and better mpg with the Amsoil. All oil filters are painted. Some don't seem to be, but they are clear coat painted. Have never seen any of them flake. Anyplace you can get Amsoil, you can get the filter, but they might have to order them which takes a couple of days.

SLOW down there guy...........

First off, I was referring to the FIRST mileage I can use Synth in the motor according to my Service Manager, so I will listen as he is my advocate, and the only one I got with BMW.

I guess I was a little messed up the way you read it.

I will not bite on the 12,000 miles on oil, at all

I change all three, every 3000, me, my option, my wallet.

After that, everyone is left on their own on this one............

I agree. I thought it was just my imagination. I switched to Amsoil this year and thought that the engine seemed louder.

There are varying opinions with regard to oil and change intervals. Do what feels best to you..

My general feeling is to follow the manufacturer's recommendation for oil change intervals. In this case 6K miles is what is recommended whether you use amsoil, mobil one, or dino oil.

With regard to synthetic change, the general concensus around this part of the country (Rocky Mountain Region) is that 18K is when you should be free to convert. I converted at 19K and have had all sorts of seal related problems in the engine and transmission. There are those "in the know" that suspect synthetic as potential contributing factor. Also the "bike sitting without use for a long time" as another contributing factor.

Regardless of all this conjecture, I am currently using Amsoil, have a bunch left, and am not sure what I will do afterward. I may just switch back to dino oil. Not sure yet.

I think all this bantering back and forth is counter productive. I still am not sure of what the benefit is to using synthetic, really....

I was getting castrol for 2.50 per quart, could use it for 6K if I wanted to and then change. The bike ran fine. Can't tell much of a difference with synthetic other then what I think it is doing based on what I have been told. Yep, I spent the money. Yep I felt good about it. That was up until over 2400.00 in maintenance issues with seals and suggestions from various "industry authorities" with decades of experience saying that synthetic could have been a contributing factor. What the heck do I know. I just want to ride the bike and not have to mortgage my home to do so.

Thank you extended warranty.. But, I have less confidence in the bike now that I have experienced these issues.

Put it all in perspective. Oil lubricates. If you want to change every 3K, don't waist your money on expensive stuff. You are wasting your money if you do.

Just that simple.
