Esters in A-RX

Frank Miller · Guru

There natural occuring esters you can go to web site of Fanning Corp and copy MSDS of there 1006. There you have it. Now if you can figure out how to make esters work 'you have the answer to your post.
How Auto-Rx makes these natural occuring esters clean metal is a trade secret.

Cool.

It sounds like A-RX contains many of the components that cost an arm and a leg in premium oils.

I have read in other posts that some esters help oil cling to metal parts. This is the science behind the Castrol GTX Quick Start formula.

With that thought process, does A-RX have that feature as well? It seems to me that an A-RX MD can really help with engine starting. Is that true?

I was mostly curious because I have also read that oils which contain a higher amount of esters are better at helping an engine run more quietly. Once again, will an A-RX MD also serve that purpose?

Everything I read (sometimes not understanding) seem to suggest that a good Dino with an A-RX MD is as good or better than virtually any synthetic out there.

What a great way to save some cash.

Thanks Frank. I really can't wait to get my auto started on a good dose of A-RX.

I posted this at another forum that I frequent...
http://www.ford-trucks.com/forums/620756-auto-rx.html

"After much reading at Bobistheoilguy, I decided to give Auto RX a try. My truck has a little over 76,000 miles on it, and has been meticulously maintained. I felt like the engine internals should be fairly clean because I always changed the Castrol GTX at 3,000 miles, and after switching to Mobil 1 never missed the 5,000 mile mark. The main reason I wanted to try the Auto RX was fuel economy, I'm spending more on gas than my truck payment! I'm about 400 miles into the "cleaning phase" (using Castrol GTX and a Super Tech filter), and noticed something unexpected - my timing chain rattle is almost nonexistent! The motor has never been this quiet, even after the dealership pulled the motor and replaced both timing assemblies. I don't know if its just the added volume (5 qts oil and 10 ozs Auto RX) in the motor, or if the product is cleaning the oil passages and allowing the oil to reach the timing chain tensioners faster. Probably too soon to tell, but I can't wait to see what happens when the application is over and I switch back to Mobil 1."

Another member of the forum is on the "snake oil" kick. Frank, I would love it if you could give me some synopsis (that I could post) of how Auto RX works so that I can help this guy see the light.

Post "Auto-Rx" Saves Money By Engmus " above. One quick note there are natural esters and there are synthetic esters. Oils with additive package that holds oil to metal is counterproductive to getting contaminants off the metal.
This is why we like group 111 oils or plain jane non synthetic for rinse phase when doing a rinse application. (we want all the dirt-contaminants-perhaps sludgde rinsed off and driven to oil filter and out of engine not stuck on oil lubricated rotating parts) Hope this helps.

With that in mind. Will the A-RX maintenance program also work better with a plain Jane non-synthetic? Is the maintenance dose still doing some minor cleaning that would make plain Jane non-synthetic the best option?

A lot of the oils I was considering, such as Schaeffers Supreme 7000, claim to plate to the metal surfaces to help reduce friction at start up. Will this prevent the A-RX maintenance dose from being fully effective?

I've used the maint dose with group III (since I have a known sludger) and it worked so well it actually removed some deposits.
