I have heard you shouldn't run the xW-30 Amsoil longer than 15,000 miles without a bypass filter. It doesn't metion you have to do that on the product description. I have also heard you should be sending the oil in periodically for oil analysis, it also doesn't say that on the bottle. I don't want to have to do all this crap. I want to run 0w-30 oil, for 25,000 miles or one year like it says, using an Amsoil oil filter and changing it every 12,000 miles or 6 months like it says and then top off the engine. Why can't it be done like that like it is advertised? What's with all this extra bull%$#*&?(oil analysis and bypass-filter)?

If your engine is mechanically sound, it should survive just fine with a 25k OCI without a bypass filter. But most members here wouldn't be able to sleep at night not knowing for sure that the oil is holding up or if any problems exist like a coolant leak or intake leak. Every engine is different and there are many variables. Just because Amsoils says it's possible doesn't mean it's possible in every situation.
So you can go ahead with your plan if your comfortable with it and see how it goes. But I would recommend a used oil analysis at 12 and 25k just to make sure. If you're happy with the results after a couple OCI's, you shouldn't have to do UOA's anymore.

SERVICE LIFE
In personal cars and light-duty trucks with non-turbocharged gasoline engines: change the oil at 35,000-mile or one-year intervals, whichever comes first.
In turbocharged gasoline engines and occasionally used gasoline engines: change the oil at intervals up to three times longer recommended by the engine manufacturer or six months, whichever comes first.
In high performance and racing engines: specified by Owner Experience/Oil Analysis.
Marine four-cycle gasoline engines and infrequently used automotive four-cycle gasoline engines: drain oil at intervals up to three times longer than those recommended by the engine manufacturer, or one year, whichever comes first.
In fleet and industrial engines: drain oil at intervals up to two times longer than recommended by the manufacturer, or six months, whichever comes first.
AMSOIL Oil Filters should be changed at 12,500-mile or six-month intervals (whichever comes first) in gasoline engines. If a Hastings or other filter is used, filter should be changed at manufacturer's recommendation.

I change my Amsoil 10W30 every 10K or 1 year and the filter at 5K or 6 months. It my be over kill to change at 10K but the year is what really sets the OCI for me.
I believe Mobil is coming out with a massive advertisement on the new Extended Drain oil that we see on the market. There are certain guidelines and a proper way of using synthetic oil to gain it's full potential usage in extended OCI.
One of the key points Mobil is trying to do is educate the public on synthetic application and public awareness on synthetic usage.
If you read what is on Amsoil's product desription(service life), it gives a broad statement on the limits of their synthetic oils.
Mobil is well aware of synthetic oil application and the key point they feel is educating the public on extending OCI with synlubes.
I for one have used Amsoil and my yearly mileage of 10-12,000 miles. I've gone 12 months OCI with the Amsoil 5w30, 10w-30 and S2K 0w-30 on a Toyota Corolla and Ford Ranger with excellent wear control and having a very clean engine. I couldn't ask for more and don't think I can go back to using dino oil. Amsoil is my oil until something better comes along for my driving condition.

MAMALA BAY,You state that you are going 10-12000 miles using amsoil 0w30. How often are you changing your oil filter and is it a regular filter or amsoil sdf?
After that magazine article (Lubes and Greases?)recommending
longer oil change intervals/less pollution the environmentitit islikelythat others will join Mobil 1. Engines in good condition will hold up under long OCI's. Both of my engines have experienced 1 year change intervals, one a GM and the other a Ford V-8. Of course mileage figures into this, along with filter changes; one was driven 300 miles per week, filterchanged at 6 months, the other much less frequently. These were driven in conditions considered "normal" and using synthetic oil. Both engines are approaching high mileage, 93k and 74k, with no ill effects.

I've gone with 10-12K with the initial filter. My driving condition is mainly higherway miles with no traffic(early morning hrs). I felt I didn't need a filter change. I usually use the Amsoil filter and if it's not available I've used the K&N oil filter.
Mulaka,
Most of my local customers run their Amsoil for a full year, with a filter change and topoff halfway through, and NEVER do an oil analysis. They also don't "dope" their Amsoil with Lube Control, Auto RX, Schaeffers #132 or anything else. I strongly advise against this practice as it voids the Amsoil product warranty. I have seen negative effects from mixing Amsoil with certain oil additives like "Marvel Mystery Oil" - I think it's asking for trouble.
Based on the oil analysis testing I've done over the past ten years, I personally recommend a change interval of "only" 15,000 miles/1 year for the regular 5w30 or 10w-30. If you use the Series 2000 or Series 3000 oils, you can extend that to 20,000 miles/1 year, with a filter change @ 10,000 miles/6 months.
As a general rule you can run the longest drain intervals in non-turbocharged, fuel efficient, four cylinder engines. Big V-8's and turbos degrade the oil much faster, but for different reasons. I wouldn't exceed 15,000 miles in a V-8 or 10,000 miles in something like a VW/Audi turbo engine.
Running 25,000 miles/1 year will get you excellent long term results. However, my goal is to get my customers optimum results, ie 250,000+ miles while retaining "like new" performance from the engine.
I feel the shorter 15,000 mile/1 yr change intervals keep the engine even cleaner internally, which is the main reason I recommend it.
If you have any questions, any of the Amsoil dealers on this forum will be glad to answer your questions.

Tooslick,
My Mercury says 5,000 in normal usage and 3,000 in commercial/severe usage. That "3X manufacturer reccomendation in fleet usage" statement by Amsoil, is that 3X the 3,000 for severe usage (9,000 miles) or 3X the 5,000 for normal usage?
If I used my Sable for deliveries, would Amsoil tell me to change it out at 9,000 miles or 15,000 miles?

Sorry for the first post mistake guys!!!
Too Slick,
I guess I am just lazy. I just want to change the oil and filter all at once. So, I guess I will run the regular Amsoil 5w30 oil and Amsoil filter, and then just change the oil when I change the filter at 12,500 miles. I wish the filter would last until 15,000, but 12,000 will have to do. Thanks for your help.

Too Slick,
I would like your opinion. I have a new 2004 Nissan Frontier XE Crew Cab with a V6 and 1600 miles on it.
It was the last '04 they had on the lot and I got a good deal. Figuring that it had sat on the lot for awhile, I immediately changed the oil to Castrol GTX 5w30 at 4 miles. I ran that until I got to 1,000 miles and then I switched to an Amsoil filter and Amsoil 5w30. Is this pretty good for this truck? If not, what would you recommend?

I can not fathom crawling under the truck just to change the oil filter. If I have to crawl under the truck I might as well change the oil also, considering the labor involved. I went 8,200 miles on Schaeffer's 5w30 and Motorcraft FL820S oil filter and the results were fine. I'm working on a 10,000 mile OCI with Schaeffer's 5w30, LC and FP. The oil filter is and will remain the Motorcraft FL820S. An UOA will follow

Note: I've always change the Amsoil filter at 6 month and top off with Amsoil while using the 5w30 and 10w-30. I've gone once with the 0w-30 on a full year cause of driving condtions but realise it is WISER to change the filter out at 6months. My take on my error and on future extended OCI, filter change and top off at 6 months but would be my choice.
Good discussion with no hacking, thanks guys.
My experiences are similar to TooSlick's.
The bottom line is: 1 year MAX for normal conditions, 6 months for severe.
Most individual people don't drive over 20,000 miles per year. And if you drive 25,000+ miles per year, you gotta be thinking MOST of that has to be highway miles, which are quite easy on the oil. The other disclaimer (so to speak) a commercial vehicle is considered severe service!

Amsoils recommended drain interval for commercial applications like taxicabs or police cars, with lots of idling, is three times the normal drain or six months, whichever comes first. This is also their recommendation for turbocharged engines. You could use this drain interval if you wanted to be VERY conservative. The Amsoil filters are good for 12,500 miles/6 months, so the same filter will last this long as well.
