A few weeks ago i changed Engine, transmission and Differential fluids w/ Mobil1 fully syn fluids. About 3-4days after the change the engine started tapping, scarry, 'cause i heard of, but never experienced tapping first-hand B4. I thought it may have had something to do w/ the ackward incline may car was parked on. It continued to tap for 25mins even after driving for 15. At the end of 25mins, stopped. Next morning i drained about 4quarts of the 10 w30 and replaced w/ 15 w50 M1 and hadn't head it since(knock on wood).However !!About 3-4 days after the initial engine tapping, I was pumping gas at the exxon station w/ car off. started car and i heared a wierd screeching almost grinding sound, (similar to when you try to shift a gear on a manual transmission w/ out hitting the clutch). After i turned car off and then back on the sound went away and has been non-existant so far (knock on wood!!). I Spoke to the guys at T3 about it and he didn't know what it could be, just advised me if it repeats, have transmission itself checked out. I still wonder if it had some thing to do w/ that Mobil 1 fluid change...

With Amsoil 100% syn, 5-30 my car starts smootly and instantly idles like glass. I swear by this stuff. If you research oil comparisons, Amsoil syn is ALWAYS on top.
I ran this stuff the whole 4 years I had my Civic Si. I raced that car in Auto-x events, and went on monthly canyon runs, as well as daily around town driving in which I redlined it often. In other words, I beat the crap out of it. The first time I ran the Amsoil, I did the Amsoil engine flush (Amsoil is one of only 2 manufacturers that makes an engine flush with NO Kerosene). I then ran the oil for 6 months, and sent a sample to Oil Annalyzers, INC. My tests came back stating the oil was "suitable for continued use" having passeed ALL tests at the top. That was enough to convince me. I know how hard I drove that car, and if the oil was still good after 6 months of me driving it, I'd go a year the next time. After a year, the oil was still clear, and amber in color.
I did the engine flush in my Q and then filled up with Amsoil 100% syn 5-30 about 4 months ago. The oil is about the same gold color it was the day I put it in. The car ran noticeably smoother after the fill (it ran like silk before, but now it's like glass, you just don't feel it at all.). Redline excludes Amsoil from their comparison charts, but includes Mobil 1. They exclude Amsoil because they know that Amsoil is better. Amsoil, on the other hand, include Redline, Royal Purple, Mobil 1, etc.
If you look on Amsoil's site, and check performance tests, there's one where a 1990 Mack E7-400 engine went 409,000 miles without an oil change!!! That's right, 409k. The motor was torn down, and every part of it showed to be in good condition. 95% of the crosshatchings in the cylinder liners were still there.
This is another great site for oil comparisons: http://www.trustmymechanic.com/motoroil.html you can download the Motor Oil Bible in pdf format for free. It's 177 pages of valuable info. This guy has nothing but good to say about Amsoil.
Quote »In fact, Amsoil and NEO synthetic oils have been guaranteed for 25,000 miles or one year since the early 70's. Red Line Oil has also recommended long drain intervals of up to 10,000 to 18,000 miles for many years.[/quote]You CAN'T buy better oil, this stuff is THE BEST, PERIOD. Period.

AMSOIL is one of the better oils, no doubt.Keep in mind tho, that the Bible was written by an AMOSIL salesman if memory serves.
Also a lot of the tests AMSOIL excels (the Timken test and the 4 ball), are biased toward oils, with Moly addtive.
ie, an oil with a given additive make-up, will perform better than an equal one ,that has chosen a different, but equal, additive package.
Both the 4ball and the Timken test, work well for AMSOIL for this reason, but are not representative of the environment in our engines.

Amsoil is the best oil, not one of the better, but the best.
The main test they tout is the NOACK test, which is becoming the industry standard test. I didn't see anything about Timken.
Amsoil is made with Genuine PAO synthetic.
To the best of my knowledge, the author of the Motor Oil Bible is independent and never worked for Amsoil. It's very unbiased, just based on ALL the different tests and research.

I wish I'd waited to post my reply on the last page untill this page!! You probably missed it as will many others that don't read the entire thread. An independent truck owner ran a Mack tractor trailor truck for 409,000 miles on Amsoil WITHOUT an oil change. All internals were in good shape after 409k miles on the same oil. 95% of the original crosshatching on the cylinder liners was still there! The pins had NO wear, the rings were all still good, every internal part of that motor showed minimal to light wear. That oil was not failing.
While what your saying about contaminants may be true, my oil after getting my results back from Oil Annalyzers, INC. had trace amounts of ANY contaminants. That was on a motor that I raced, did probably 12 canyon runs (sea level to 8000 feet and back down) and redlined every single day. I trust experience, and my experience tells me that Amsoil (and many other Synthetic oils) can be run for a year without change, and NO negative side effects.
Please do me a favor and read my reply on page one.

the truck test you refer to has little to do with how a motor oil will hold up in our passenger cars.for one,the miles put on most trucks are almost exclusively all long highway trips,with idleing at truckstops the norm,and very few cold startups for the miles driven,and the crankcases are huge,25-50 quarts is not uncommon,along with the use of bypass filteration systems that almost polish the oil!I do agree though that amsoil,mobil1,and redline are 3 of the best synthetic oils that are relativly easy to obtain,and each one can claim to be "the best" depending on how thwy are examined-using any of the three will probobly make the engine outlast the rest of the vehicles economic life.

Regardless of how much oil is in the truck, that's 409k miles of hauling ton's and ton's of freight. Not an easy job on any motor.
One of the things mentioned in the Motor Oil Bible is that Amsoil, Neo, Redline and even Mobil 1 have recomended extended oil-change intervals since the 70's. True, pure synthetic oils DO NOT break down. And they don't absorb contaminants like a Dino oil.

I am having good runs with Valvoline Syn Power 5W30 and 10W30. When changed the oil is as golden in color when first put in. The engine Runs smooth & Idles like glass. My older engine (255K) seems to agree with me.
How much is this AMSOIL syn? Is it good to put in an engine as old as mine? I don't want to spring leaks everywhere. The detergents in the Valvoline SynPower have been kind so far.

I actualyl think we need to disagree...
The people who think they can get away with the ultra long oil changes of amsoil obviously are sold on that and will defend it, and if the oil analysis proves it, theres not much us people that are old fashoined can say... It kinda gets into your head that "I am doing something better than the next guy", and really you can make your qualitative data prove your point anyway you want to go...
There will be probably just as many sources (outside of the sales company-- independent) that tell you that ANY oil gets cruddy after 90 days as there are that amsoil or any high quality synthetic will go forever.....
I am not flaming anyone here, but trying to make light of the situation.
Bottom line: as long as you got clean oil in your Q al the time, I dont really care what you use or what your OCI is...
Edit: Another thing I forgot to mention is the respect of knowledge fred has about this sort of stuff..... Whatever he recommends I know will be about the best you can do, and VERY economical!

Keep using what works for you. SynPower has good detergency, so if it comes out clean and didnt pick up a lot of gunk, that means there isnt any gunk to be found.Your engine is likely very clean!
SynPower is a group III synthetic and therefore not quite as capable as a group IV oil like AMSOIL/Mobil1 in some applications, but I feel its additive package is good and it has yielded good oil analysis results in engines.
Keep with the 10w-30 vs the 5w-30. in your application except for the midst of winter.
There is also a SynPower 5w-40 which brackets your oil specs but that is not so easy to find (autozone sometimes meets some of teh toughest VW specs and MB specs)
I have used AMSOIL, SynPower, Mobil1 and Syntec (in 0w-30 which actually acts more a 0w-35 in the Syntec as long as you pick up the german version).
I feel all of the above oils do well in opur applications and tehre are other lesser oils that also do real well, depending on your application.
