AMSOIL Experience

[THOR74]

I've been running my 5.0 for 13 years now on either Castrol Syntec or Mobil 1 synthetics. Here in Canada these cost about 9-10 dollars per quart.

Yesterday I decided to try AMSOIL for 14 dollars per quart. I had no expectations and thought it was probably more of a gimmick than anything else.

However, I must honestly say that I noticed a marked and genuine power increase at all operating ranges. It feels like someone lightened my car. I know how this vehicle normally runs, but a little throttle goes a longer way with this new oil.

I'm impressed and it was worth the money to me. I was already running some pretty high end oils and would never have believed what a difference using this product could make.

No I'm not some jackass who spent too much for oil and is now trying to justify it by falsely convincing myself and others that the car has more power now...

And, no, I'm not a paid stoog for AMSOIL...

Does anyone out there have AMSOIL experiences they can share, good or bad?

I personally run the stuff in everything i own that takes oil, including my chain saw and two stroke equipment. my one buddy sells the stuff and he swears by it. it definetly makes things run smoothly!

The real question is, does the cost justify the rewards? Are you really going to go one full year or 25k miles (whichever comes first ) without an oil change? If you put any appreciable amount of miles on your mustang, the costs will almost certainly outweigh the advantage. Considering a regularly maintained 5.0 engine will easily last 200k+ miles and 25+ years on regular dyno oil, I just don't see the advantage.

well its not 14 a quart where i live, im sure prices are different in certain areas. i change mine every 6k and the price is about the same as conventional oils if you change every 3k.

Unless you can get it for < $5 a quart, you won't be close in price compared to a standard SAE oil (mobile, quaker state etc.). Let's not forget too, most manufacturers recommend a 6k mile (or more) oil changes. The only places in todays day and age that recommend a 3k mile change are the lube shops...and it doesn't take a brain surgeon to know why.

 

[tims 86]

i believe its around 45.00 for five quarts and a wix oil filter, its worth it in my opinion. i think 6k on regular oil is pushing it, though you need to figure in driving conditions.

Worth what? What does it give you that regular dyno oil wont?

6k on dyno is really the standard recommendation is 6k + miles (I believe Ford's recommendation is 7500 miles).

Superior Zinc, Phosphate, and TBN additives. The 3 most important properties in any oil.

All of which can be found in uber cheap Rotella T.

Perhaps I should have worded my question...what does it do for you that regular dyno oil doesn't?

i run amsoil in all my motorcycles and love it. Also give joe gibbs oil a try. Ive talked to alot of circle track racers and they say its just like amsoil but it dropped there oil temp 20 degrees with no other mods. Also the guy at my local machine shop said hes torn down race engines that with valvoline race oil would need a rebuild but with the amsoil he could wipe down the bearings and slap it back together and there was 0 wear. Im a firm believer in amsoil

Question: Do synthetic oils have a tendancy to atomize (aerosol) more readily than dyno oils, inside of the crank case?

Go 15k+, flow better in extreme cold climates, not shear to a lower viscosity in extreme hot conditions, and is available in a wide variety of weights (Rotella is not).
Is it worth the price and or switch to a full synthetic if you change your oil at 3k or 5k? Not in my opinion, every dIno oil on the market can pull that (some better then others).

No and I have never heard of any oil atomizing at all.

And that was really my point. For those that change their oil at the recommended manufacturers intervals....it's not likely they'll see the benefits in the lifetime they own the vehicle (and beyond).

I started using Amsoil after reading an extensive test report that showed why it is better. My bike was first, right away I noticed way smoother shifts. The problem with most motor oils is that they loose their properties and you're not getting the proper effect even if you change it every 3K. Someone mentioned Rotella T. As indicated on the bottle itself, it is not 100% synthetic. I personally think it's worth it and as a preffered cutomer, I'm paying the same as Mobil 1. Soon I'll upgrade to dealer status.

That's just my opinion on the subject. Now, if you have some time on your hands here is the read. The test is done comparing motorcycle oils which have different properties, but it was enough to sell me on it.

So what exactly is it going to do for you that conventional motor oil wont? I'm not asking about how superior it is to conventional...but rather what it does for you? Your paying an extreme premium for it, right?

 

[RatStang]

Well of course it does... That crank repeatedly splashing through that pool of oil kicks all kinds of oil up into the crank case mixture. That mixture is what gets picked up by the PCV system and returned to the intake for burning.

Currently, I'm having an issue with the PCV picking up too much of that atomized oil and sending it to the intake (PCV air velocity too fast, PCV pickup too small for my boosted app).

So I wonder if different types of motor oil have different properties where the atomization is concerned. I've seen reference that synthetics tend to become airborne particulates more than dino-oils but that was only one.

Like I said, I noticed right away that the bike shifts way smoother. I mean there is no question as far as that goes, it's like night and day. I was skeptical at first, but decided to try it as it was about 20 bucks more for an oil change and that's the loss I was willing to accept, but the difference was really noticable. So for that price, it is worth it for me. Hope that answers your question.

When you're talking about a bike that shares it's motor oil with the tranny it's a whole different ballgame.

 

[mustangphil]

Well yeah that's true, but conventional motor oil didn't work as well. So that's enough to convince me to use it on wife's 07 Camry as well. Do I feel the difference on that? Probably not, but after reading the full report, I believe that it's better for the internals in the longrun. And the difference in cost is not siginficant enough. Keep in mind that I'm running it for 15K and only change the filter every 5K and top it off. Not using it on the Stang, as it has a small leak somewhere on the bottom and I don't use it that much. Once I rebuild the motor in that (in some distant future) I'll dump Amsoil in it as well. And that's just my opinion on the subject.
