Question for Amsoil racing oil users - 03/31/09 02:34 PM
The closest auto parts store to my house stocks most of the Amsoil line and I'm considering using their Series 2000 in my Challenger. Do you folks who run Amsoil in your race or street/strip cars use an oil analysis program to determine your change intervals? Since the stuff has a high TBN level (12), it "should" be able to last quite a while and not need to be changed as frequently as oils w/ lower TBN ratings. And, at $10 a quart, I'd hope it wouldn't need to be drained as frequently, either. Any other comments about the product are appreciated, too.

Hey Brad I hope you feel this is on topic because I was going to start an oil thread asking about synthetic oils. I have been reading about different synthetic oils with different base stocks Amsoil is supposed to be POA base stock oil with ester base stock being the best and POA being second best but much cheaper. My transmission builder uses amsoil in his 1500 hp nitrous engine on alcohol and is very happy with it. Maybe some of the chemists will chime in.

I tried it, runs suggested it was probably .02 quicker in the quarter. That was going from 20W-50 Valvoline to Amsoil 10W-30 back in the mid 90's. It is also a good test on how well your rear main is sealed up. Bearings looked pretty much the same. I believe synthetics are better oils but IMO not worth the hi cost. I went back to the 20W-50 Valvoline and am still running it. I never used anything other than my judgement to determine change intervals. I try to change every 50 - 60 passes. This is my

You should contact member "Locomotion",Myron Piatek.He swears by Amsoil and has been using it for many years.There was also a thread about synthetics and a post was made about the price being cheaper that $10 a quart.

What Amsoil says is that the oil is good for 25000 miles. You change to their oil and filter, and when you reach 12500 miles you replace the filter and add a quart of oil, then drive another 12500 and your ready for a complete oil change. If you are using the by-pass filter along with a full-flow filter and have a oil sample checked in the lab you still change the filters and add oil put you dont change the oil untill the sample does not pass.

I use Amsoil also and have had the oil analysis done last year. Right after I sent in the oil sample I found out I had a thrust bearing issue. So I was expecting bad news from the sample. I got an e-mail and a phone call from the lab about the results
On the report was a note that the use of race fuel will raise the level of lead in the sample. Many large fleets I have inspected at have oil analysis done on all vehicles as part of there maintenance. It is a good look into what is going on inside the engine. Many issues have been found before they knew a problem existed with a piece of equipment.

There are those who are afraid of it. And there are those who knock it. Then there are those who actually do it.
Extended Oil Drain technology has existed since 1972.
The links below show how Used Oil Analysis (UOA) can support a lube manufactures claims. Independent person... Independent lab...

Hey CompSyn .... you speak well of the product ... just like anyone who has their hands in-the-profit pie of Amsoil sales.
How about a person like myself ....... that is just SKEPTICAL of the whole Amsoil "deal" ?
SKEPTICAL .... of just WHERE do all the combustion by-products go during the 25,000 miles that this oil is being used. Does this oil have some way to "magically" make these by-products disappear?
SKEPTICAL ..... that these sales people are just not up-front with everyone on WHY these Amsoil products are so expensive. SIMPLY .. because it is a multi-level-marketing program that it HAS to be that way ... because so many people in this pyramind have to make a profit.
Doublely SKEPTICAL .... since lots of these Amsoil advertising claims CLAIM that their product is so much better than the competition. Yet no independent proof is ever supplied.
And NO .... I am not talking about the infomercial like Prolong ....when they had Al Unser driving a Viper around a race-track with NO OIL in the motor at all. And then after an hour or so ... saying the motor was fine.
Well .... enough from me for now ... I have been up since 6am yesterday ....time to hit-the-hay .... but I will be-back.

Well I worked in a Freightliner dealership back in 93/94. When the N14 cummins engine came out in the trucks. Cummins sent out a bulletin on extended oil changes. It provided that those companies who used oil analysis could go to 30,000 miles intervals with Mobil 1. Jim

Re: Question for Amsoil racing oil users - 04/03/09 12:41 AM
Anthony, yes bypass filters. we were looking at going to a synthetic blend and upping our oil change to somewhere around 60k as i remember but for what ever reason it didnt happen.
i really have no opinion one way or the other on oils. i run the oil i run because thats what the guy that i bought my cam from recomended. and im gun shy after i lost the cam in my 383 that had been in the car for 10 years.
Brad sorry for getting off track.
...and their marketing BS ...
