Amtec???
 

hi guys

ive seen this stuff called amtec advertised and has been designed for bad compression and general health of our engines but i wanted to see if anyone has actually used it and they had noticed anything ie improvements or problems? is worth using to make sure compression stays healthy as the product states?

cheers guys :confused:

Got a link? I am only finding references to a microphone amplifier product.


I'm guessing it's not going to help, and may harm, our engine. Most piston related things like that are either snake oil to begin with, or completely inappropriate for a rotary.

Never heard of it.

I'm finding discussions from other sources that are referring to it as a "Chlorinated Additive"

Which is a compound from the 1930s that is cheap to produce, scores will in certain lab tests, but is very harmful to the environment, hazardous to handle, destroys any attached catalytic converter, and can not hold up under even moderate engine heat.


I recommend you research how and why compression is lost first, before randomly selecting products that you think might prevent it. Watering your dying lawn with a garden hose will only work if the cause of the dying grass is lack of water. If it's poisoned from something in the soil, the watering will do nothing.

Learn the WHY first. THEN theorize on solutions.

apologies i mispelt it, link here though Ametech Engine Restore Oil - Engine Restorer & Lubricant

i do understand the whys but i was trying to find a product to "stop the grass becoming poised as you put it" or at least slow the wear and tear down until i can afford to look at new engine

How can a single additive "restore" different metals, with different properties, at the same time? All of this without interfering with soft seals and gaskets...

Same answer. :)

yeah i know which is why i was seeing if anyone had ever used it or if its just another gimmick to try and get money out of people, thanks for the help though guys,

Just premix. When the engine is worn, rebuild. Then premix again.

premix is something ive looked at through and through though and i cant seem to find a definitive answer as some say no unless FI or if you well maintain theres no need, i know in the series 2 there is a mention of a third injector for apex seals but again no definitive proof for wear for the middle of the seal?

See the new owner's thread, post #10 for the methods of protecting the engine.

Premix is recommended, but lack of premix probably won't be what kills your engine. Apex seal wear is certainly a viable failure method, but it's less common (in my opinion) than excess carbon and overheating.

Yes, the series 2 center injector helps with apex seal wear in the center, but it isn't a suddenly perfect fix either.



And you won't find a definitive answer on ANY topic here. NONE. It's because we all have opinions, and they are all different. If you only want 1 answer, only ask 1 person.

thanks verbose i didnt mean an answer in that way but wanted see if there was actually any evidence for using or not using thats all, i understand each engine is different and each persons right foot is different but i would have thought there was some form of data from the amount of engines that have failed :-$

Nope, no data.

Mazda doesn't share any, and any data here is heavily skewed toward people that have had problems (people don't hop on to report that everything is good), and even that information is skewed toward generally less negligent owners.

I made a data collection attempt a few years back, but with even about 150 engines that people filled in all sorts of information on, there simply isn't enough to draw a conclusion.

So it's all theory, with bits of information from people that pull apart engines (which also isn't 100% useful since often we have no idea how it ward driven or maintained, or we do but it's a coolant seal failure that makes it hard to tell the impact of premixing or whatever)

When people reply to facts with opinions trying to discuss a matter becomes a waste of time... That's what happens with premix.

With that said, i always did it :)

yeah thats the problem ive found when trying to decide whether or not to do the premix option and install the adaptor so as not to use the general oil for the seals.

The SOHN adapter is recommended pretty much all around. I haven't found anyone that thinks that dirty 4 stroke injection is superior to clean 2-stroke. Though some people think that "adding a hardware failure point" isn't worth it.

Premixing is a personal choice, since plenty of people agree, and plenty disagree.

with a sohn adapter you'd still have to premix.
So just premix.

They each address a different issue. One does not replace the other.

You are still injecting dirty oil without a SOHN, and you still aren't getting much oil to the center of the apex seal with it.

mazda rx8
 

ive used ametech in my 2004 rx8 due to hot start problems and I cant believe it it done 90 miles since using this and the car is getting better at starting when hot they say within 300 but seeing the benefits already
I was sceptical as hell at first but got sick of waiting 3/4 of an hour to start the car but now
More or less straight away dont get me wrong is takes a few turns but it will star and is getting better

amtec
 

Hi pirelli 01 how much did you have to put in many thanks

Similar experience here.


Only added maybe 100km ago, but warm start performance appears to be a bit better. Still sometimes need to give it 4 or 5 tries - but not 8 as before. Sometimes starts first time now.


Impossible to give a scientifically conclusive answer, because other variables may be in play - differential between environment temperature and engine temperature may happen to be more favourable as winter deepens here, for example.


Will try to remember to report back here once I have done 300 miles!

Did the Amtec work?

Hi - to be honest it is too soon to say anything conclusively as I have not done the 300 miles you are supposed to do before noticing a positive difference, but warm starting now seems little different to it was before - I may have just struck a lucky combination of factors initially that made warm starting easier. Now typically takes 6-7 tries, with winter temperatures now colder here.

So what happened?

Did it make any noticeable difference?

Nope. In fact things got worse & my engine lost so much compression it stalled going up a hill. Ended up biting the bullet & having an engine rebuild (costing almost what the car is worth)
