Amsoil engine oil
 

Does anyone here run amsoil in their stock/superstocker? What weight? I picked up a sponsor from a small amsoil rep and he wants me to try some. I have never used any amsoil products so any info would be great, thank you

I've been having good luck with the Amsoil 10w-30 synthetic Dominator race oil in my Super Stock 427. Other than a rod bearing issue I had last year, which was not due to the oil I am using, the bearings look perfect every time it's apart. I also use their synthetic ATF and gear lube with good results.

I have never used it but member "Locomotion" has used it for years and should have a meaningful response when he sees this.

Re: Amzoil engine oil
 

The first thing about having Amsoil as a sponsor is making sure you spell their name correctly. LOL . That being said I have used their products for years in my Race quads and sleds. Also have used their assembly lube in engines.

Great oil, I use 10w30 in my stocker

Re: Amzoil engine oil
 

We have ran it for a long time. Actually had the oil pump pick up break off and made entire 7800 rpm dyno pull with 10 psi pressure and the bearings looked new. Yes, the dyno operator was a bit red faced, but it turned out alright. That's what really sold us on it. We use the 10-30 Dominator, but I know some people with tighter bearing clearances than us run the Dominator 20w all the time. I've been told its slower than most oils on the dyno, but if your looking for protection, its a great choice.

We started using the 5w-20 Dominator racing oil in our Jr Dragster many years ago and liked it so good we started using it in the super stocker when Taylor started driving it. We turn this thing 8800 RPM in the quarter mile and after 175 runs bearings looked brand new.I didnt even replace them when i freshend the engine last spring. We also run Amsoil ATF and gear oil.

AMSOIL Sponsored The Engine Masters Challenge. Every participant was required to use Amsoil oil. They got to choose which oil and the weight.. all for no charge. I did the tech for 10 years and as far as I could tell there was never an oil related failure. I took apart all the winning engines for inspection and verification. I never saw any damage from oil breakdown. Saw some part failing...but nothing the oil had a hand in. I did see some roller lifters fail from abusive cam profiles. RJ Sledge was the Tech guy in our team that made sure they poured in the AMSOIL and no one sneak anything in other than their oil.. By the rules No additives allowed.

Been running 5W20 Dominator for about 4 years with great results. Refresh showed very little wear after over 220 runs in my 360 Stocker. Jim

Re: Amzoil engine oil
 

Seems kinda sad, but AMZOIL never seems to have been "accepted" by racers. The people that use it seem to swear by it, but the people that don't seem to have nothing good to say. Anybody know of a historical incident or something that gave it a bad rep?

Re: Amzoil engine oil
 

I have been using the Lucas Synthetic Racing oil. It seems to work well and bearings show very little wear.

However when it is cold it leaves goo in the pan that looks similar to assembly lube.

Does the Amzoil do this? I think I have read the Valvoline does not.

Thanks,
Bill

Re: Amzoil engine oil
 

In ten years,we have never seen Amsoil separate. I believe what your seeing is the additive package separate from the base stock oil. The higher the grade of base stock used, the less needed in additive packages.

Re: Amzoil engine oil
 

Gibbs 5-20 (XP-1) is bad for separation when cold,lots of snot in the pan,pick-up etc...gsa612

Re: Amzoil engine oil
 

In talking to Lynn Groom, the Amsoil engineer, when at EMC events I have learned a lot about oil. In our conversations he got down to engineering terms, which we could converse on because of my engineering background. There is no doubt they have a product based on quality rather than cutting base stocks for profit motives. Base stocks set the initial starting point. Then the chemicals and additives are added. Some of the additives can attempt to "cover" for the molecular shortage of inferior base stocks. This is esp true when some MFG's use a low grade type base stock and chemically enhance it to perform like a higher grade. This is a simple way of saying it matters when dealing with the molecular structure of the base stocks.
IMHO the problem with drag racers using it is that they don't have a lot of distributors and a wide spread distribution system. Most guys don't keep inventory on hand and wait till the last minute to do the oil changes. I know my customers/buddies and I'm just like them in a lot of ways
BTW. Amsoil Motorcycle/Harley oil is outstanding. I got a local repair shop I did machine work for try it and it stopped a lot of problems they were having. ESP lifter and cam issues

Re: Amzoil engine oil
 

I have been using their stuff for a few years now with good results, their break in oil goes in every engine I do, and I then switch to the Dominator in race engines. I typically use 10w30 in my stocker.

Re: Amzoil engine oil
 

I used to use Amsoil 10-30 Dominator in my bracket engine. I believe it saved me from myself a long time ago. I had a needle stick and when I went to start it you can guess what happened. It spun just a bit and stopped. I was ignorant of what can happen and wanted to race that day so I pulled the plugs, spun the engine over and pumped out the alcohol that had built up in a few cylinders. The engine started and I raced on. Made 85 more passes on that engine before tearing it apart. When the head came off and I looked down you could see #1 piston c0cked in the cylinder. When I got it completely apart I couldn't believe it lived. Here is the rod that came out of it. I used to have a pic of the bearing also but couldn't find it. This is embarrassing but oh well.



The only reason I stopped using it was because it wasn't convenient to get then. I use Driven XP-7 now.

Here's some good links to Amsoil specs and explaining their multi grade and Dominator oils, he has many more interesting videos about oils.

Re: Amzoil engine oil
 

I have been using it for well over eighteen years. With nothing but praise! As far as why it is not being used by most racers, PRICE. MHO

Re: Amzoil engine oil
 

I have used amsoil in my snowmobile and motorcycle engines for years without any problems. I even had them warranty a gallon jug that split on the seam. Stand up company. Never any issues in these vehicles.
I tried the Dominator 10-30 in my race car and here is my story.
I had been using Red Line 5-30 in my FE for at least 10 years, my amsoil rep
gave me a great deal on a case of the Dominator 10-30 to try. I put it in the car
and only made one test and tune all year(3passes). My garage is climate controlled,
With no Humidity issues so I left it in the car until spring. I also run VP fuel, and when I went to drain the fuel and the oil the following spring, the oil came out in Clumps, with some rust coloring mixed in. I had etching inside the pan, but no other ill effects thankfully ..... still have 6 quarfs of amsoil on the shelf probably 7 years old. I have a full size cooling system in my car, usually stage around 140 degrees an get back to pits around 180-190 degrees so hopefully it was warm enough. Dont know how warn the oil gets, unfortunately.
Some kind of chemical reaction, with the fuel, or between different oils absolutely caused an issue for me . I never leave synthetic oil in my cars when they go in storage now
