I've been thinking of switching to Amsoil 10w30 for my 1988 ford bronco ii with 44,800 original miles on it, it's been run on dino oil since new but I want to give it the added protection of a synthetic like Amsoil to make it last for many miles to come. What do you think about Amsoil? What do you think about their 25,000/1yr drain interval?
Amsoil?

I would have no problems switching to a synthetic, however it might be prudent to do a little bit of maintenance first.
I would consider running a course of AutoRX through it first-just to make sure it's clean and ready for the synthetic.
I would also suggest that you consider doing UOA's every 7000 miles or so until you hit the 25K mile mark with the synthetic. Diving right into a 25K OCI with no UOA would worry me a bit...

Do you think it be okay if I didn't run the auto rx through before I switch to the amsoil because I really don't want to mess with that stuff.

Who would want to subject their 17 year-old vehicle with so little miles to possible torture like that?
When you read that 25K info, did it contain an *asterisk* outlining the necessary means in order to accomplish this with any sort of oil life remaining after 24,999 miles?
What does it say?????
I'll bet it says you must drive your car like dearly, recently departed Grandma & Grandpa traveling all highway in non-polluted Heaven -- with the only other traffic being Angels flying overhead... lol

Averaging 2635 miles a year...I don't see any problems with 1 year intervals.
My F150 gets it's oil changed in June.
Auto-rx would be a good idea to help clean things out since obviously this thing either sat forever or isn't driven much, but a full clean/rinse cycle would take over a year.

I plan on driving it more than 2635 miles a year in the past 4 months I've put 1700 miles on it and this summer I will be driving it much more.

There are UOA's on this forum that run some very impressive extended oil changes with high miles.
Here is an example:
Almost 25,000 miles on Amsoil
It is over 7 months, mostly highway with a new engine but looking at the analysis it seems it could have gone much farther.
I would trust it to 10,000 miles for my first UOA in my own engine and see if I would extend it or not. ...Thats probably all I drive over a year
See what the UOA's get and you can decide how long you want it.
I saw a 1986 convertible once before that had mileage around the 50k mile mark or so, but thats because the previous owner didn't know how to fix it(only a failed fuel pump tho, $150), and he got the car for $250 spent after the fuel pump and drove it about a year before selling it for $250 after getting a deal on a pickup.
What I would do and have done recently in a few cars is change over to Amsoil and run the first OCI to 5000 miles then change the oil and filter. After that I change the oil once a year with a filter change halfway through. This works for me but I only drive about 10,000 miles a year in the car I drive a lot and the others see much less mileage. I think the short OCI first is a good idea it rinse to old stuff out of the engine.
* When used in mechanically sound non-turbocharged engines. Change oil in turbocharged engines as recommended by the vehicle manufacturer. Replace AMSOIL oil filter at 12,500 miles or six-month intervals, whichever comes first(other brands as specified by the vehicle manufacturer).
(From 10w30 ATM bottle label)
"OF UP TO..." and "MECHANICALLY SOUND" are key words used. You'll need to UOA to determine mechanically sound for sure. Fuel dilution from short trip driving, very dusty conditions, in-efficient air filtration, engine design etc. would all make 25K unlikely for most vehicles. The 25K is not an absolute as I read it. Uoa is the only way to know how much you can get out of it in your particular engine.
If I didn't think 10w30 ATM wasn't good, I wouldn't have bought some.
I've had excellent results changing many high mileage engines over to Amsoil using the following procedure:
1) Install a new high capacity oil filter and run a pint of the Amsoil engine flush with my time tested (25+ years), modification of the directions on the can. Run the engine in neutral with the flush for a full 30 minutes, @ 2x the normal idle speed. How to do this??? Ease a piece of cordwood or a brick up against the gas pedal until you get correct rpms on the tach....
2) Drain the oil/cleaner; change the filter again to an Amsoil or Mobil 1 filter and install the Amsoil formulation of choice (It almost makes no difference which of their xw-30 or xw-40 oils you use, quite honestly). Anything from their 0w30 to their 15w40 will work year round any place in North America, in any mechanically sound gas, or light duty diesel engine. If you want a recommendation, I'd probably use their 10w30 in this case, but the other formulations will work equally well.
3) Use a service interval of 15,000 miles or 1 year, WHICHEVER COMES FIRST. Change the filter only and top off the crankcase at 7500 miles or six months - again whichever comes first.
Note: If you are only driving 6k-8k miles a year, in all likelyhood you will be able to run the same batch of Amsoil for two full years and with just a couple of filter changes. If you decide to try this I would strongly recommend testing the oil after 12 months and changing the filter if the results warrant further use of the same oil. I have run two year change intervals in my own vehicles on several occasions with excellent results and posted those results on this forum.

Which Amsoil? They have two, one in GroupIII and another in full synthetic?
MolaKule: I was talking about the fully synthetic
I was at my local Napa and they carry an impressive selection of Amsoil.
I have a big jug of Mobil1 EP to work through, but I am not averse to picking up Amsoil in the future (since its only three miles away).
Can someone give me a very short summary of the product line? I gather they have a wide range of products (https://www.amsoil.com/products/cars/index.aspx - whoa!) In paticular, I've read snippets here and there that some of the oils are better than others (other than TooSlick saying that they are all pretty much the same about two posts above this
)
Any point in using a certain Amsoil in an 05 Corolla over M1 5w30 EP?

No. If M1 EP performs even just as well as the GF-3 M1, in a Toyota you will not see any difference using Amsoil. You might see a bit more Fe with M1, but it's really so insignificant that it's not worth worrying about. Amsoil's biggest problem IMO, is that it thickens more then it should. Of all the oils they make, I like the S3k and 5w-40. The others are on par with M1 but the new EP stuff might even be better....the cost of Amsoil 5w30/10w-30 is actually cheaper then the M1 EP. The S2k/3K are their top of the line oils.....in all honesty, I'd like to see more from Amsoil. I'm a fan of their oils (not marketing) but I don't see as much value in them as I once did with so many oils now readily available.
