Amsoil Interceptor Synthetic

[97xcr440]

I have never heard of any issue's running Amsoil in anything, so I hope 97xcr440 that what happened to you was fluke. That being said I bought 6 gallons of it and will be running it in 3 mountain sleds where half the time the throttle is pegged wide open. I still have some Cat oil to use up and will most likely switch one sled at a time over as I run them out.
I have always ran the cat oil but since the price and availability lately is questionable I decided to go Amsoil. The other up side is come summer I can run it in all the Jet skis, so I too will be down to just one oil for the toys.

sorry not a fluke, go to hardcoresledder and do some reading, I am not alone.

What exactly was the issue with running the AmsOil? You say dry bearings, does that mean you inspected them, or you blew up something?

I also run AmsOil in EVERYTHING I own, except my Suburban. I have NEVER had any bearing or engine failures running AmsOil. My father has been running it in his old 1973 TX 500 since the mid/early 70's. Hand mixed to 100:1 ratio, and never opened the motor since, and still has perfect compression and runs like the champ it is. I have over 20k miles on the 3 sleds I currently own, and have run nothing but AmsOil.

Yes they were inspected. There was no film of oil as with using klotz,vesII oil. I am not the only one to note this problem. It has been talked about to great length on other sites.
It seems as interceptor does not have the film strength of other oils.

If you/your father have good luck with it fine. I am just letting the guy know it is not a cure all/best oil out there. There are oils out there with better ratings and cheaper prices.

Ok, but is not having a film of oil on the bearings a good thing or a bad thing? I mean, if you have not had a failure, the oil is obviously doing its job. And perhaps, as is the case with power valves gumming up, less film or residue is a good thing, am I mistaken here?

Just because it does not leave a film of oil behind does not mean the oil is not doing its job.

As was the case with my fathers sled, there was little to NO carbon build up with AmsOil, and I would suspect that to be a good thing.

Not trying to start a pissin' match, just trying to determine why you think it is not a good oil for your application.

I would think that the synthetic oils used by racers and motocrossers like the Luccas. and Klotz smokless oil will protect your engine best. These racers are spining these two strokers at up to 14000 rpm!

I know that outboard motor injection oils in use today,are designed for above freezing temperature usage.
But sleds require oil that have additives in them to keep the oil thinner (when its below freezing) to ensure flow of oil with the cold gasoline/ air mixture .Thus you should use oil designated to snowmobiles.

I use the luccas or Klotz smokless snowmobile oil I use it my chain saw, boat, sleds

I hesitate on using Injector oils that have little or no color in them simply because Its hard to tell if I previously mixed the fuel. and the saws and augers usually dont have oil injection.

Unlike conventional oils, Most of these synthetic oils (especially smokless oils) dont burn in the combustion chamber because the combustion chamber temperatures are not high enough to burn these synthetic oils These oils simply lubricate the crank bearings and coat the cylinder walls then pass right through combustion chamber out the exhaust. (great for engine with power valves). You will observe the synthetic oils on the snow or garge floor at the exhaust pipe.usually looks like little black oil specks. if theres water present it will look like a white gummy residue film.
I heard that CITGO is made from recycled oil. Dont know if that would make a quality difference.

Every engine builder I have taked to has said you need some residual oil on the bearings and internal parts to resist corrison and upon start up. Mine had none, they were dry to the touch.

My engine with klotz is spotless and has oil to the touch on all the internal componets.

no black spot with my sleds burning klotz.

Not sure about citgobeing recycled. Doesn't smell like recycled oil and it does a good job on my other sleds. It is highly rated also.

Unbelievable! Looks like a fight starting over what oil to use. 97, you made your point, you don't like it-so don't use it. Along with others, I have used it for years in all my 2 strokes and have been trouble free. I'm not saying that thats the only oil out there that will do this but it has obviously proven itself or they wouldn't be a top seller. And wanderer, there are a couple of reasons behind running your oil low before the switch. 1) less chance of the two oils not being compatible, (I think they are) 2) you will get the most benefit from your "new" oil if its not diluted. I think you will be fine but the wonderful and not so wonderful thing about the internet is you will always get mixed opinions. Best thing is to try to cipher through it and make your own decision.
Sorry to rattle but "why can't we all just get along" lol

[XCR440]

Not starting a fight, just wondering what if any failures were due to the oil.

No failures, oil is doing its job. Bottom line.

I've been running the Amsoil Dominator Racing Oil in my 2001 800XC and have had no problems with over 5000 punishing miles. Getting very little wear & tear from what my dealer is telling me upon the last inspection. I also like the Klotz, but tend to get a little sic to my stomach when riding behind friends sleds who are burning it. Although, I've heard the same about the smell of the Amsoil as well, lol.
