https://www.amsoil.com/storefront/asm.aspx Oh boy, another oil thread. BTW, this is for my F-150 pickup, not Buell. I am contemplating trying the Amsoil 0W-20 (ASM). COmbined with the top of the line Amsoil filter, AMsoil claims a service interval extending up to 25,000miles or 1 year. BTW, the Amsoil 0W-50 is the replacement for the OEM specified 5W-20, so that should be okay. Frankly, it scares the hell out of me to keep oil in my truck for that long. Is this fear unfounded? Am I programmed by the oil manufacturers to change the oil religiously at 3,000 or 3 months? Opinions please! | ||

If you live in the north and do lots of cold starts fuel gets in the oil and that is bad. If you put on lot's of mile's then I would say OK. | ||

i'd only be scared about the filter; i think you would be ok if you swapped the filter out half-way. add oil to replace what was in the filter, if you aren't adding to replace burning oil anyway... doug s. | ||

mini cooper intervals are 15k from the factory. | ||

i know many people that do it with amsoil in both their bike and vehicles, and NO problems....use your own judgement...oh btw these vehicles have used amsoil since new and have over 150k+ mi. Jake | ||

I became an Amsoil dealer since I'm starting to use it in all my rides. I'm going to go to 10K on my wife's SUV and have the oil tested to see where it's at. I'll probably post up the info once I get there. I have 2 track days on my XB with Amsoil in it. I have 2 more TD's this year and I'm going to test/change the oil after that. | ||

Do an oil sample every 5k, and change it when the lab says it's time. | ||

I know guys that do that with conventional oil. | ||

Per the factory, my wife's MB E350 has once a year oil changes. MB uses Mobil 1 and a proprietary filter. That got me to thinking so I tried Amsoil in my 04 Dakota. I've got nine months on it so far. I'm getting a bit nervous but it still looks fine. | ||

The answer lies not in the manufacturers' claims but in the oil analysis. Because no two vehicles are the same (conditions, driving style, mechanical variances, etc...) the only way to know when your oil needs to be changed is to have it tested. I started having my oil analyzed last year, and I have gotten interesting results. The Amsoil MCV 20W-50 from my '08 XB12R tested extremely well after 12 months and 6 track days (688 track-only miles). In fact, the TBN tested "as new" at 11.2 and Blackstone Labs recommended a 15 month/9 track day interval for the next test. The Mobil 1 0W-30 from my '07 Porsche 987C tested acceptably after 20 months and 7,082 miles, with a "mildly low" viscosity and a TBN that read "fine" at 3.7. Blackstone recommended a 9,000 mile/24 month interval next time, but I have replaced the Mobil 1 with Amsoil AFL 5W-40 European Car Formula and will have it tested after a similar period of time for a back-to-back comparison. I personally don't feel warm and fuzzy about "mildly low" viscosity and a "fine" TBN of 3.7- that seems low to me. The oil analysis will answer my question at the next change. I will be having my '07 Jeep Grand Cherokee CRD (diesel) serviced later this week, and will be sending its Amsoil AFL 5W-40 in for testing. It has 9 months/10,000 miles on it, and I'm very curious to see what the results are. The bottom line is that no one has to guess about when to have their oil changed. Having an oil analysis done removes the guesswork from the equation, and will tell you whether the claims of your oil manufacturer are true. In my case, Amsoil has performed as well as they claim, and that's very reassuring because I happen to be an Amsoil dealer too. Pick your oil, have it tested, find out for yourself, and adjust accordingly- the truth is out there, and it's not hard to get. Fresno- as for the extended interval, Amsoil only warrants a 25,000 mile service life on the ASM oil if it is used in conjunction with their EaO synthetic media filter. The EaO filter must be changed at a 12 month interval even if you have not reached the 25,000 miles, so the combination is actually a "25,000 mile or 12 month- whichever comes first" service interval. If it were me, I would change it at either 10 months or 15,000 miles and send a sample to Blackstone for analysis. If the test result is good, then I would know that the claim is substantiated and would have no reservations about going to the full 25,000 mile/12 month interval as claimed. | ||

Strokizator- My wife's '03 C240 has a 10k mi. interval with M1. I bought the replacement filter (Wix I believe) from a local auto parts store for about $12. That sucker is the strangest cartridge filter I've ever seen and uses 3 different size o-rings. My nearest MB dealer is 100mi. away and there's no way I'm going there for an oil change (probably not for much other service either). | ||

Saab listed a 10k oil change interval for their 2000 era 9-3 (oil cooled turbo). The exploding engine reputation from that bad idea really drove down the value of the surviving cars, so those of us that found a used one from an owner smart enough to ignore that advice got some SMOKING good deals. Those that took the advice got some SMOKING hot engines.  (there was a PCV routing problem that compounded the problem, but the long change interval eroded all margin for something to go wrong and have it still be survivable). | ||

On board filtration systems are the way to go. Systems like this-- http://www.amsoil.com/storefront/eabp.aspx Diesel engines in class 8 trucks can go well over 100k miles with systems like that. The key is filter changes and oil analysis. This will prevent you from throwing out good oil, keep the oil clean, and the lab reports can tell you if you're getting contaminants in your oil like dirt, fuel anti freeze and abnormal amounts of wear metals from bearings. | ||

Very much like Redbuelljunkie, I run the 20W-50 in my XB12R race bike. My AMSOIL dealer suggested I change it at the beginning of the season last year and leave it in. I checked it and added as needed but never changed it after five full race weekends and a track day or two. The oil sample came back from an independant lab showing it to be as good as regular 20W-50 would be brand new. I'm a believer, now. I recently switched my '06 Silverado to AMSOIL and will follow their recommendations. I do like the idea of pulling an oil sample at 5K though. | ||

At Inland Kenworth where I used to get my tractor service done, they used to drain my oil, clean it, change both filters, pump the oil back in and top it off with some fresh. They only actually changed the oil every 100,000 miles. 14.8L Caterpillar, but still... oil lasts a long time under the right circumstances. | ||

Good oil... to bad I can't run it in my WRX. Amsoil and Subaru's don't mix well. | ||
| Redbuelljunkie |
Amsoil and Subaru's don't mix well How, exactly? | ||
| Bads1 |
Subaru's for some reason it goes right through them. Talked to many owners that stay clear of it. Mine I run Rotella. | ||
| Redbuelljunkie |
Gotta prove it with some facts before I'll believe it. I would be very interested in finding out why a particular oil would have an issue with a specific manufacturer if that oil meets all the requirements as specified by that manufacturer. It would be easy to prove if it was in fact true... is there any empirical evidence? | ||
| Bads1 |
Yeah I put in my car. It a 2009. I put it in at 2000 miles. At about 2000 miles I did a oil check. Hmmm 1/2 qt. down. So did aliitle research on Nasiac.com. which is basically the Badweb of Subies. Found several talk's of the same problem. I did a change to Mobil 1 for a 2000 miles. Hmm no problem. Now I run Rotella because of the reports on the oil. Then..... just a couple weeks ago I was at the Brian Redman challenge at Road America. I stopped by the Amsoil tent at the track. Told him what happened with my car with there oil. He said they have had reports that the oil was a problem in various Subaru model's. I'm assuming Turbo cars. Anyways he went on to tell me his Son has a WRX couple years older then mine. His car has the same problem with the product and his Son runs Redline. My car now has 10,000 miles on it. It has ran Rotella now for close to 4000 miles I'd say and its great oil.

4 miles is a lot these days  | ||

Oppp's sorry bout that.... fixed it.lol | ||

Oil analysis is sound advice. I probably won't exceed 15,000 miles in a year, so I'll get one 8 or 10 months into it. I have confidence in Amsoil and trust it will perform as promised--especially after hearing from you guys. | ||
| Cataract2 |
I normally run my oil for 6 months in my truck and then change the oil and filter. | ||
| Redbuelljunkie |
Bads1- it's not quite empirical evidence but you have piqued my curiosity. Can you provide the specifics about the oils you mentioned (brand, weight, ratings, etc...) along with the Subaru OEM oil recommendations? Also, does this reportedly only occur during break-in (less than 5,000 miles) or at various mileages? This is the first I have ever heard of a specific oil (Amsoil or any other) that has an issue with a particular manufacturer- if the oil in question does meet the exact requirements of said manufacturer. I'd especially like to know if anyone has had an oil analysis done in this situation. If it can be shown that there is an issue with a specific oil and Subaru, I would be keen to find out why. It certainly should not be blamed on the oil- Amsoil's record speaks for itself. I don't see how a mechanical design would affect one oil and not others- especially if they have the same weight/specs. This leads me to believe it may be a weight/spec issue... it is most curious. Please tell me more... | ||

Very hard to believe Amsoil itself does not work in a specific model car. I don't even see how that's possible. | ||
| Redbuelljunkie |
A quick google search resulted in these findings that suggest a Subaru mechanical/design issue: www.repairpal.com/blog/subaru-turbocharger-issues www.boostplanet.com/subaruoilstarvation.htm www.notnormalmotorsports.com/documents/subaruturbo version.pdf And threads discussing that it's not just Amsoil that these engines are burning up: www.toronto-subaru-club.com/forums/showthread.php? t=123432 www.iwsti.com/forums/2-5-liter-liter-factory-motor /156315-burning-oil-lets-try-figure-out-14.html | ||

Yeah those link are actaully for 2005's through 07's. Its something that was taken care of actually. I'm around a group of heavy Subie enthusiasts in my area. 4 of the guys had problems with the oil in our group. I pretty much stayed away from it. Doing aliitle research of the forum others had issues.... 1/2 qt. or more losses before oil change is due. Most seem to like Rotella,Redline,even Castro. These guys much like Buell owners really like there Subies. Now I have nothing against Amsoil. I've just seen enough reports from Subaru owners that I have stayed away from it is all. Rotella is great stuff but only if your running catless. The cars ask for for 5w30 but alot of guys use 5w40 as do I.  | ||
| Redbuelljunkie |
Gonna have to see some actual proof before I can move it out of the "myth" category. I would sincerely like to see empirical evidence showing how one brand of oil that meets the type, viscosity/grade, and API category/class required by a manufacturer could have an issue that matching oils from other manufacturers don't. It just doesn't add up... | ||
