I did some searching and found some posts about oil but in many cases the poster excluded Amsoil.

I have been hearing about Amsoil mainly in the 2-cycle market but not much in auto. So I'm all ears, what's the sales pitch for Amsoil??

 

Look right down below in the sponsor links.
The oil is ok but has no great atrabutes far and above others.
You don't see it widely mass marketed like other well known lubes but is small dealer networked.

 

Why do you need a sales pitch?? Go to their website and decide for yourself if it is what you want. Amsoil has been around for a long time and advocates "extended" drains using thier oil/filters. If they simply wanted your money then they would recomend that you change your oil/filter every 3K using their oil/filters. They don't....you figure it out.

 

I run the 0w30 Severe service oil in my truck and I change the oil once a year. This is about 12-15K miles. I check the level occasionally to make sure I have not lost much and top off if needed. Usually I use a quart between changes which is pretty good considering Ford says a quart per 900 miles is normal for the 5.4L. It is good for as much as 35K but that is with bypass filtration and oil analysis. I will be adding a dual filter in the spring and start OA to see how long it lasts on my truck. Amsoil has been making synthetics since 1972. In my opinion it is the best synthetic available. I now have 85000 trouble free miles.

That is where I was going with this is their recommended 7500 mile interval. Are standard oil filters like Fram and Purolator ok for that interval? Also, what about for towing applications, is it still ok to go that long between changes?

I have run full synthetic in a 350 that has over 250,000 miles on it but I have religiously changed it every 3,000 miles. Most people say I'm wasting my money by changing so often, but I say that's why it has 250,000 miles on it.

 

If you're gonna go that far without changing your oil, spend the extra $$ and get a premium oil filter. No cheapo Dollar Store filters like my dad. I use a Fram Tough Guard Filter and Castrol GTX 5w-30, and I change my oil every 3000 miles.

 

That is why you have 250,000 miles! YOu are doing exactly what you should be, and if you keep it up you'll never have any oil related engine problems. I have a customer with a 97 Yukon that has over 450,000 miles on it. He changes at 3000 miles, and usually averages 3 oil changes per month. (he's a traveler) I read the amsoil stuff, and on their website it says during the warranty period of your vehicle you ahve to follow manufacturers recommendations. I don't believe in extended intervals, because I have seen the results. I can show you a picture of an Altima 4 banger that had 10,000 mile intervals and when I opened it up, it looked as if someone had taken a crap in there, several times. I personally would just stick to the synthetic you are using, and keep up the 3000 mile intervals for a worry free truck!

 

go to www.amsoil.com and find everything you'd ever want to know about oils, dino vs synthetic, then make your decision based upon FACTS not opinion. (and that's all I'm saying about this subject)

 

The secret to the extended oil change intervals is the bypass oil filter setups. The extra filter traps ALOT smaller particles than your normal filters, and this allows you to run the oil longer intervals.

I cant say Ive ever heard of any engines with problems that are running Amsoil for extended intervals.

 

I think the only spin you'll get with Amsoil is a spin around the block to empty your wallet.

People think too hard about oils nowadays. Use the recommended weight for your engine. Use something with the latest API certification. Use a good filter. Change it regularly. Sleep well at night.

 

AMEN!!

I have never met a person that has had a problem with their engine due to been using an specific oil brand, just use Motorcraft oil, it's the cheapest oil in Wal-Mart and it's what Ford recommends.

 

Um, does anyone else see the irony in that statement?

 

This reply is only to bring you some other things to consider with "greatly extended" oil change intervals.
The synthetic chain molecules that attribute the oils multi viscosty attributes are not permant and all but disappear within 5000 miles.
As this happens the oil gets heavier and acids deveolpe attacking internal parts. Cold temps makes this even worse.
There is no filter system that will have any benifical effect on these actions.
The 7500 mile oils may hold contaminants in suspension longer but that is about all you get from them.
Take some time to study the oils on the shelf that have the MC designations on the container.
You will find at the present time, the Motor Craft 5w20 has a 930 rating while all the others are still at 929 or not listed.
It's up to you to either launch into a long experiment or just do the recommened oil and change intervals. The 5w20 quite low in price but not a "cheap" oil.
Once up on a time I went to a hardware store and ask for a cheap paint brush. I was promptly told 'WE DON'T SELL CHEAP PAINT BRUSHES but inexpensive ones'. Ok- ok, just stick it then! I will get one somewhere else.

 

Blugrass,
I am thoroughly convinced that synthetic oil is far superior to mineral oil. There must be some truth to it as using synthetic oil on a new engine disrupts the normal wear which causes the ngine to break in.
My dilemma is on the recommended service, and what you said makes sense. Especially in a truck used for towing, I have a hard time swallowing the concept that it's ok to go 7500 miles no matter what oil you're using.

You might not encounter "oil system problems" using "cheap" oil, but it's only basic physics and common sense that the more you can reduce friction in the engine, the longer it will last.

 

I'm not sure I get what you're saying there. Are you trying to portray that you shouldn't use synthetic from mile 1, but after the first change? If so, how would you explain factory synthetic loaded vehicles such as Mercedes and BMW?
