I was reading this online about damage done by synthetic oils in trannys

Eclps0,

The debate between synthetic vs standard oil has been discussed quite a bit on here.

I'd suggest checking out this thread.

https://www.rx8club.com/series-i-tech-garage-22/rotarygods-rotary-oil-tech-blog-69805/

The link primarily talks about Synthetic Engine Oil but does talk a bit about tranny oil...

 

lol, hardly a definitive survey of owners/users. Snythetic lube is way better as is normally is much more resistant to thermal breakdown and all the other nasty stuff that eats gears.

 

When consumers use synthetic oils, they are usually trying to utilize them to fix a problem. Most consumers don't just change out their tranaxle oil...they do it because its "making a weird noise" or "feels funny" or "is having trouble shifting to 3rd"....so they throw in some synthetic fluid based on their friends recommendations, hoping it fixes the problem.

The problem isn't fixed, and the thing that was about to break, does break, so the people turn around and blame the synthetic oil, forgetting that they had the problem PRIOR to putting in the synthetic oils.

People think synthetic is some sort of magical fairy potion that might have negative effects on something, because its magical, and obviously out of a dragons **** or something to that effect.

Synthetic fluids are just "consistent" manufacturered molecules instead of random chaotic ones (dino based). Thats why its tougher, and can withstand more heat/bad things. When everything is the same, you've got less variables in the equation.

A bunch of people awhile back tried to blame a ground of transmission failures in supra's on redline MT-90...the analysis's shoot them straight down...all the failures had absolutely nothing to do with the oils, and everything to do with owner abuse and "pushing the transmission beyond specifications". The oil was still good and doing its job, but its not going to perform miracles when you try to slam a shift in while spraying nitrous, outputing a good 200 ft/lbs more torque then stock.

 

his logic is very scientific and quite infallible.

and if he did select the wrong product, that is definately RL's fault because they should have published an extensive guide to the uses for every weight of oil on the bottle.

 

Lol, that is a great statement!!

The rationale behind the Red Line tranny lube, from what I've read, is that it's not "too slippery", but has just the right coefficient of friction to allow the syncros to do their job. I've ready plenty of testimonials not only here, but previously on Miata forums, to improved shifting. I've got some in the garage ready to put in soon.

 

Yeah, that part where he says he couldn't even figure out whether he had the right product was classic! :D
You couldn't write funnier stuff if you tried!

S

 

wait, its not magic? **** I totaly got riped off by that elf at pep-boys!!!! ****! :D

 

yeah, they've really gone down hill since the elves did the hostile take over of control from the auto-gnomes

 

reminds me of the "I've been running 87 octane, but then tried two tanks of 91 octane and my RX-8 ran like sh-t" thread

 

For the love of GOD! How many morons, MORONS!!!! are going to keep thinking that synthetic oils are the source of all their problems? They aren't!!!! Quite the opposite. Do some research people!

Here's the biggest source of car troubles. Is everyone ready for it? USER ERROR!!! It's not to say all problems are caused by this but inevitably a large majority of problems happen because of some action or (preventative maintanence inaction for that matter) on the part of the vehicle owner.

Why are synthetics always used as the excuse? Next time I have a car problem I'm going to blame it on my antifreeze. Maybe I should blame an engine failure on conventional oils. Maybe I should blame McDonalds because I spilled MY coffee in MY OWN lap and claim them responsible because they made it and I bought it from them!!! When will the stupidity end? Every single person that claims that synthetics are bad is quite simply ignorant. Here's a more plausible excuse, Al Qaeda is tampering with your engines. Prove me wrong! I say it must be so since it is the only thing I can think of. Therefore I must be right. I don't see where the oil comes from before it is in the bottles therefore it must be tampered with. A dumb excuse is a dumb excuse.

Can anyone tell how pissed off I get at stupid people?!

 

20% of US oil comes from the Middle East. Al Queda is in the Middle East. I'm certain that 20% of all car troubles are directly attributable to Al Queda.

No really! You've gotta believe me. I'm serious!!!

 

terrorists are breaking our cars!

 

I hear all car bombs are filled with synthetic oil.

 

Synthetic oil made me bury my mother-in-law alive in the back yard.
Is that wrong?

 

not at all not at all. you are fine jeff

 

Good. I was worried because that stuff is expensive!

 

I think most of the fear stuff comes from the fact its manufacturered, instead of extracted from some dead animals bones.

Same people are probably against genetically engineering bacteria to produce vaccines, or genetically engineering plants to survive in harsh environments. (The irony being they eat genetically engineered food, and have had tons of vaccines)

If its man made, it can't possibly be good!
Damn those humans, they screw everything up!

 

I only get pissed off at synthetic people. They cause all the problems.

 

You can flame synthetic people because they resist thermal breakdown.

 

Now that is funny!

 

Fred -

The screwed-up transparancies in your Rockin' Ramses is giving me seisures.

 

what screwed up transparancies? it seems alright to me...

 

All the fun and ignorance aside, synthetic oils, either tranny or engine, can damage certain parts. No, not the synthetic base stock, this is indeed pure, stable and very inert. That one is fine - too fine, to the extent that to blend in other components (anti wear and anti oxydants, viscosity modifiers, detergents and dispersants, etc.) you need to add few percents of a good solvent. Searches on the web seem to indicate esters. Now those are great stable molecules too, but good solvents (BTW, aviation engine oils are ester-based, so no reason to suspect them, right? wrong - never ever use aviation oils in car engines, the whole thing will fall apart). If parts of engines or transmissions are not from materials inert to esters, they will be first swolen, then get ripped appart by some moving part. Gaskets and seals made of plastics or rubber will do that if the wrong material is used. This was the case with older rotary engines, hopefully solved for the Renesis. Unless OEMs check for this, and nowdays they do, only experience will tell you if the synthetic oil you used is good or deadly... I would speculate that since so many Reneses ran on full synthetics for about 2 years, things should be fine. But this is not a proof or a guarantee, so it is totally up to you to risk using it - and to make up a good excuse to do so

 

Keep in mind that the oil manufacturers themselves are aware of the materials used in automotive engines, as well as incorporating improvements needed to certify each successively improved API service classification, and I'm pretty sure I read at least one, if not more, of those API updates related to seal material compatibility. When I started using Mobil1, if I recall, the industry was in the process of switching from API SD, to SE. We've gone through a good chunk of the alphabet since then. I don't get this speculation about whether Renesis seal materials are up to the task when people have been running synthetic in the RX-7 for many miles and those cars are at least 10 years old.
