OK...call me strange but here it goes anyways!

I have been trying to convince myself to switch over to the Amsoil XL7500 synthetic 5w30 oil for some time now. Well I did the Amsoil switch over @ 18,000km.....HOLLY CRAP, it feels like a completely different truck now!!

Power is better than before, better mileage, and smoother running....call me weird but it sure feels a ton better than when I was using conventional oils.

I am now sold on this Amsoil stuff...better yet my next oil change is not for 6 months!

COOL!

 

Butt dynos are notoriously unreliable, especially when you are looking for an improvement.

Fact: Most Amsoil performance improvement claims posted by dealers are pure unadulterated horsehockey. Any synthetic will give you slightly better performance... but if you think you are in the 5 percent or even 2 or 3 percent, it just taint so.

 

I didn't feel anything with my AMSOIL changeover....

I don't know what I was expecting. Maybe some of the elated and erotic feelings 2001 experienced.

However, after reading everything I could get my hands on about synthetic oils, I have decided that AMSOIL is the only sensible move toward preserving my engine over using conventional oils. I have friends who swear by it, and I have a 1994 Cadillac with 184,000 miles, that is still running like a swiss watch on AMSOIL. I truely believe it will go on and on forever.

One trick that I would like to share with you guys is this: The camshaft needed replacing in my old chev flatbed truck. After they had it all apart and were about to put it back together, the head mechanic said if I wanted AMSOIL back in the engine I would need to bring it into them. Then, said a strange thing. He said, "Come look at your engine, and if you wouldn't mind sharing with us ... what do you use in your engine besides AMSOIL ... we have never seen an engine that looks this clean after 160,000 miles .... it's like brand new inside!!!"

I shared my secret with them and I'll share it with you. Just about a hundred miles before an oil change I always change the oil filter and drop out enough oil to add one quart of Marvel Mystery Oil to the crankcase. I run the engine enough to get it up to full operating temperature, (into town and back) just before draining my oil. During the 100 miles, the mystery oil has time to dissolve and remove carbon deposits, varnishes and other nasty deposits that would normally cling to the rings, cylinder walls, valve guides and other parts of the engine. It holds them in suspension and they drop out with the dirty oil. Even AMSOIL won't do that.

I have used Marvel Mystery Oil for years and finally, after seeing the inside of my engine, I have proof positive that it works to keep the engine clean. I know a lot of guys who will turn up their nose at this tip ... but that's their loss ... not mine or yours.

Of course, 90% of the impurities and dirt enters your engine hrough the air filter. If you live in Detroit where there is yellow air and acid rain, your engine is sucking that stuff in every time it runs. So, even a good K&N Air Filter might need to be cleaned a little more often than they recommend. If you live in the dry desert you have a gritty dust problem to combat. Let common sense be your guide. But, Mystery Oil helps to remove all of it at oil change time.

I agree, I don't think you can feel the PERFORMANCE increase unless you convince yourself it is there. However.................

'01 Screw, 5.4, 4x4: changed engine, transmission and xfer case to Amsoil at 10,764 miles. MPG to that time 15.42 overall, all fillups recorded. 10,764 to 15,910 MPG is 16.20. What is that in percent?? 4.8 ??? 5.05??? anyway you look at it, it was worth it to me, since I am putting on 6400 +/- miles per month. I pretty much drive the same all the time on the highway, very little in town miles. Am now at 29,000 and mileage is holding at 16.05.

My last two trucks--'97 f150, 4.6 4x2 and '99 f150 4.6 4x2--each had over 155,000 miles at trade. '97 was bought by a friend and he is up to 225,000 with no eng/trans probs.

Two or three generalizations may apply here:

1) Just about any name brand oil will protect todays engines when changed at mfgs recommendations
2) I believe all synthetics are better oils than conventionals.
3) I feel $92.00 every 25,000 miles beats the heck out of $25.00
every 3,000 miles.

IMHO

 

Not to discount your data in anyway, I have read numerous posts where members did not realize full mileage until the 10-12k mile range, such was the case with my truck.

I whole-heartedly agree with #1 and #2. #3 depends on how worried you would be about voiding your warranty with Ford. For $100.00 I will continue to change my oil at the 3-5k mile range and have the peace of mind that my warranty is intact.

I have also read where people claim that their engine was so much smoother and quieter after changing to synthetic. Maybe because I wasn't expecting this to happen is why it didn't happen?

 

I don't have any doubt that in older engines synthetic can make significant differences in operating noise levels. I think it is vehicle to vehicle though, some will be quieter and some will not. My old Bronco II was noticably quieter and smoother when I changed the synthetic. Just put new synthetic in after 3500 miles.

I agree, I would change more often than 25000. I hope you at least plan to change the filter a couple times during that period, when filters become clogged, the bypass is used, all the dirt remains suspended. Not good for engine....

 

The only difference I noticed was more leaks (which I expected). The mind can play games on you, if you expect to notice a difference, you will.

 

Sidewalk,

Wrong, it varies engine to engine. Until you experience it, you wouldn't know. I didn't expect any differences other than longevity of the engine.

 

2000Lariat:

Thank for your comments--they are very fair. Someone else on another board mentioned that talking about synthetic vs conventional oils can approach religious intensity. Seems that is so.

There is no warranty problem with Ford--they have refused to tell Amsoil that use of Amsoil will void the warranty. But there is that small area of doubt that tells us we don't want to be in the middle of a dispute about what caused an engine to shell out. But with the large numbers of Fords I have owned, I suspect there are almost no failures in Ford engines in the warranty period.
Comfort levels have a lot to do with it.

My biggest problem with 3-5K changes is that they come so frequently for me--and I don't like to change oil when on the road.

Another reason for the use of Amsoil is that I have a '94 Bronco that routinely blew oil out the transmission vent onto the exhaust pipe when pulling loads in 4x4Low. Hasn't happened since I switched the trans over to Amsoil ATF.

I haven't noticed decreased engine noise, smoother idling or 13 sec passes at the strip just because of Amsoil, but I did get a pay raise soon after the changeover.

 

Damn dude, I was talking from personal experience. I have made mods to vehicles where I thought I felt a change, and there wasn't, oil was just one of them. I have also made mods where I expected a change, and didn't notice it.

Case in point:
MSD 6AL ignition
MSD coil
MSD 8.5 mm Superconductor wires
K&N
modified are intake
Electric fan
Full tune up (I don't think it was ever done by the previous owner)

I made these mods all at the same time, and I didn't notice a difference. However, if I change my spark plugs in my other car to a different model or brand, I feel a difference (sometimes). That is because my mind is making it up, or because it did make a difference. But I have no hard proof.

So in other words, don't tell me that my personnal experiences are wrong, because you weren't there.

 

Sidewalk,

Damn dude... live what you preach... don't tell me I am imagining what I was experiencing.... you weren't there....

I don't think I discredited anyone elses observations... you however....

 

Wow, lots of odds and ends coming out here.

If you have leaks already, synthectics will leak. If you dont have leaks, and they they start after synthetics it is because the dyno oil left deposits that plugged the leak. Synthetics clean that and it starts leaking again.

For mileage, I did not notice a lot in the engine. My ranger got 1mpg after the Amsoil in the engine. The tranny and transfercase, after switching the truck had a lot less friction and I got a 1mpg in the F150. I also got another 1mpg in the ranger doing the tranny and transfer case.

Performance, well even if you do NOT get any gains, not changing oil for 6 months/1year interval is WELL worth it! Heck it even can please the tree huggers! Less used oil!

 

Some people take things way to personal. You directly said, pointing me out by screen name, I was wrong and have not experienced that situation. Now, if you mean not experienced your situation, you are correct. But if you mean that I do not have experience with various engines, then you are incorrect. Apperantly, since my post came directly after yours, you assumed that I was talking directly to you (that, and you were also talking about a BII). I was making a general statement.

So, moving on...
There are message boards at The Ranger Station and The RRORC for Rangers and BII's, since you pointed out owning a BII.

 

Sidewalk,

I believe you posted

The mind can play games on you, if you expect to notice a difference, you will.

as the next post following my experience of reduction of engine noise...

I didn't make any claims of any experiences or experience you have. All I stated was that sythentics can make significant differences, in my case, noise reduction and that it varies engine to engine. So, unless you where there when I had my Bronco II, you wouldn't know.

I don't believe I ever question whether or not your experience of no noticable difference was true.... just posted my experience.

I believe your general post questions others experiences by making a blanket statement like the one above.

Better check your own posts.... before you call names.....

Not sure why you listed the forums. If I still owned a BII I wouldn't be here, I'd be there.

I am not taking anything personal, but for one to discredit others simply based on their own experiences, well, that just don't get it.

I never called your experience wrong... I called your post wrong, insinuates that any differences may be imagined... and in essence discredits anyone that has experienced a difference.

I no longer own a BII, I have a SuperCrew, have fun over there.

You assumed that since your post was before mine (and also related to a BII) that I was commenting on what you said.

Since you pointed me out by name, and then said I was wrong, I assumed you where questioning me.


It was a blanked post, it was meant for people to think about and then question themselves. I force myself to do that everytime I make a change to any of my cars.

Please point out where I called names, because either it isn't there, or I can't see it.


A good friend of mine has an F-150 and told me that I should check out these boards. I was invited by one of your own.


I still believe that you are taking it personal. But that is my opinion alone and should not be argued.


That makes more sense now, about the post being wrong that is. However, "any differences may be imagined" is exactly what I was trying to get at. "May" is the key word.
