my new van calls for 5w-20 but i can get 0-30 in amsoil, iam new here so would like to hear some of your thoughts, also my son has just rebuilt 2 mitsu vr4s twin turbo and after about 200 miles he is using 5w30 mobil 1 , would 0-30 amsoil be better, it appears ever one here prefers amoil.

If you new van says 5W-20 is required - which is different that saying it's only recommended, plus it lists no other oil weights as options, then you should stay with 5W-20 - at least until the warranty expires. Amsoil does carry oil in 5W-20. Amsoil XLM-XL comes in 5W-20. Some here (even some Amsoil dealers) prefer it over over the more expensive Amsoil labels.
AMSOIL's 5W20 is their 7500 mile severe/normal mile or 6 months whichever comes first. The 0W30 AMSOIL can be used in nearly all applications that call for a 5W20. The advantage is this oil can be used up to 17500 severe miles/35,000 miles or 1 year whichever comes first. The disadvantage is it costs about $3 more a quart. If you post year/make/model/engine of the above vehicles I'm sure someone will post the appropriate products. Or you can go to https://www.amsoil.com/scripts/runisa.dll?amsoiloaf:index and look it up yourself.
In nearly every typical property and test that I've seen, the AMSOIL products seem to outperform the Mobil 1 products.

Use the 5W-20 XLM Buy from a site sponsor.
If your new van calls for 5w-20, please use it.
I'm assuming that you have a warranty issue to deal with
here also, so please keep to factory spec's until your
vehicle is out of warranty.
If you choose to use Amsoil, please take Pablo's advice,

I believe that 5-20 and 0-30 specs are very close. How new is your car? What are your OCI's with the OEM? What type engine? etc, etc.
I use the Amsoil 0w30 spec for 5w-20. I haven't used the Amsoil 5w-20 but after 10,500 miles(110,800 miles) with the TSO, oil is remarkably clean. This is my 4th run with the TSO. The reason I like the Amsoil 0w30 over the Amsoil 5w30 which I had used prior is I did experience MPG gain which actually cost less in it's usage. Also the TSO is very shear stable as I've tested on a mountain uphill climb, the oil doesn't miss a beat. I was impressed! I also experienced a cooler running engine, the TSO takes a beating and keeps the engine from heating...it just refused to heat up!
That was my experience comparing the two oils, the Amsoil 5w30 and the Amsoil 0w-30. Performance wise the Amsoil 0w30 just takes the oil on a different level. I don't mind paying the extra...in fact for my application the TSO cost less, it's more shear stable, keeps my engine cooler and start up is the best I've experienced, the oil just flows so quickly.
Engine had seen nothing but Amsoil from 1K miles. I do yearly OCI 12-13,000 miles. For my application, the Amsoil 0w30 had a higher performance over the Amsoil 5w30.

my van is a 3.8 liter dodge and is used mainly for short drives, taking the wife where she wants to shop, and twice a week to golf course, mainly short drives, by the way iam 69 years old. i never thought about using amsoil until a guy who mall walks told me he is a amsoil dealer, he was telling me about a test where conventional oil is compared with amsoil by setting them both on fire in a metal tray and the conventional oil turns to sludge, seems to me i saw that 30 years ago. i have 2 of my sons cars, one is a dodge twin turbo stealth and the other is a mitsu gt3000 vr4 which is highly modded . both have been totaly rebuilt and computer balanced the stealth is now about 350 hp but the vr4 is about 500 hp, not tuned yet , after about 300 miles on both i put in Mobil 1 5w30 ,ther is aforumn for these but they are using everthing from 5-30 to 15-50 .but i live in ohio and it was -6 today, the twin turbo cars are put to bed for the winter so temps on them does not matter . thanks again for letting me rant
On the Mobil 1 5w30 cars, I would not be using this oil in a highly stressed application as I believe it is primarily a fuel economy oil for longer drains in non-modified engines. For better protection of those modded engines, I would pay extra for Redline oil, or at least bump it up to a 40 weight Amsoil(check with Pablo or TeeDub for best one) if primarily run hard in hot weather. You might even consider one of the Schaeffers series 9000 oils, 5W-40 or 5W-50. A lot depends on typical oil temps and what these engines historically do best on, the part I really cannot answer for you or you son. Others here probably know what would be a good bet. Amsoil 0w30 is a very good oil and may do great, but for these engines I would be using something with a good dose of moly such as the Redline or Schaeffers for best protection.
Amsoil 0-30 @ 100c cST = 11.2 Viscosity Index = 195
Amsoil 5-20 @ 100c cST= 8.5 Viscosity Index =165
This is a very small difference and I would run the 0-30 in all your cars and buy Eao oil filters. If one of the sponsers or the guy who hit you up sign you up for preferred status, preffered deal it will cost you about 30 bucks a gallon delivered and last each car a full year or 15K.

I'm in the process of changing all my gasoline powered vehicles over to the 0w30 Amsoil from Mobil 1 5W-20. My 2004, 5.4 F-250, is my test case. So far, I can tell no difference between the Mobil 1 5W-20 and the Amsoil 0W-30. The milage has even stayed the same..... 12.7 mpg...... :>)
