Synthetic oil has proven results. I aint a cheap ***, and I think I can afford the price.

Idemitsu has been selling *FULL SYNTHETIC* oil for YEARS and its Rotary oil that Mazda use. So, tell me something my friend. If Idemitsu is lying, Mazda should've sue them long time ago. But if Idemitsu is not lying, so what Mazda did was nothing but cover their *** marketing.

There are a lot of things that are great for racing, but not suitable for street use. Nor for a car's longevity. Remember that a racing engine does not have to last much more than 24 hours, usually less. Even in those series where a race engine lasts for a season, it's going to be torn down and rebuilt after running for a time that's miniscule compared to the running time of a street engine.
Not taking sides on synth vs dino - there are probably great dino racing oils that are not suitable for street use. But you're pointing to something irrelevant for your argument.

do you guys know that in Japan, there are TONS of Full Synthetic Rotary oil. Some of them just rebrand oil but hey, at least IMO the japanese people knows how to move forward unlike the rest of the world.

IMHO, synthetics have two benefits. One is that they provide better protection in hard running, like racing. The other is that they last longer than regular oils in normal service. If you're not racing, or at least really running the **** out of your car, you're squandering time and money by using synthetic and changing it frequently.
But if it makes you happy, go for it. All of us spent $25K to $35K (new) for our 8's, even though you can buy cars for as little as $10K (new). The extra bucks were for happiness. Don't feel compelled to argue the point - just enjoy what you enjoy.

reading the forums lately has gotten me typically interested in going ahead with the swap to synthetic oil. quite a few of u guys have done it, and i have heard that many of u just do an oil change to swap out the oils, just instead of using the dino oils, u put in the synthetic, and after approximately 3-4 changes, u should be completely synthetic. But, i really feel stupid for asking this, is this a good idea to allow the different oils to mix? Many people have done it without having any problems, but 'could' there be any problems?

No. There should not be any problems.

The tone of the thread doesn't bother me. It's nothing compared to usenet chatter. We also don't have encorez in the mix. But I still worry about the fate of those industrial furnaces burning the used synthetic you drop into the recycle drum every 2000 miles.

All Rx-7 have to pass emission testing in order to be certifiedfor sale in the USA and Emission testing is done on mineral oils. Because rotary uses oil injections, Synthetic oil could reduce the life of the emission components such as catalytic coverters and o2 sensors. These parts has to pass 50,000,80000 and 100,000 miles durability testing,which was performed with minerals oils. The Rotary burns oil to lubricate the apex seals, and synthetic burns at a higher temp than mineral oils. Repeated shorts trips may cause the synthetic oil to build, leading to spark plugs fouling. Finally oil sparyed inside the rotor cavities can contact the rotor oil seal " O " rings and oil inside the combustion chamber can contact the housing seal "O" rings. Long term exposure to synthetic oils may cause these seals to swell and deteriorate,resulting in an exchange in engine. This Y mazda does not condone the use of synthetic oil in Rx-7. Also Y SCCA Racers use synthetic oil and y can I use it? Cause Racers synthetic oils for many reasons: Racers frequently tear down and inspect their engines,thus replacing all seals, Racers do not need emissions certifications, Racers cars are not covered under warraty. Oil in the i/c and air supply hose on all turbo rotaries is a normal functions of the pcv systems to control blow by. During boost , the pcv valve closes and boost pressure from manifold is directed through the engine housings,oil filler neck and into the air intake funnel in front og the front turbo. From there it passes throught the front turbo and into the i/c and throttle body,This coats all intake air system with oil and is an indication of a NORMAL OPERATION od the pcv system. This is not a defect. I hope this answers most people Q about synthetic oils.

Many years ago (1993) in discussing all the minor problems I was having with my FD (bought new in Aug '92), I discussed this directly with the guy who runs the Mazda service tech training school in Pleasanton. He and I got on the phone with an English-speaking engineer in Japan. The gist of that conversation was that the main reason Mazda does not recommend using syntheitics is because they did not want to (or have the money to) test all the different blends out there. They agree it's better for the turbo, but for the reasons you note, there could be some synthetics that would cause problems. The engineer agreed that most would not, but was not willing to divulge any that had been tested and cleared. In a sense, if you're using a synthetic, it's a crapshoot.

How long did it took you to find these stupid stuff ?
Doesnt really matter, it just shows that how STUPID you're, period.

My summary.
If you don't track a lot and don't plan on keeping your 8 for 100 mile sthen dino oil is just fine at normal oil change intervals. Synthetic oil use for people who fall into this category is a waste of money.
If you do track hard or it's a track only car then sythetis is the way to go because regardless of what oil you use, your engine will likely need a rebuild before 50k anyway.
I know there are more categories but the bottom line is that 90% of the RX8 owners fall into the first category.
Oh, and if you disagree, then you disagree. You won't convince me otherwise. If Mazda thought the Renesis would benefit from Synthetics then they would recommend it like all the other manufacturers that recommend the use of sythetics in there engines. Some people think Mazda only made the statement against sythetics because they have not done extensive testing of the different synthetic oils in the rotary. There are negative issues with using it, and these negative issues outweigh the potential benefits of using it. Now of course, if you race then.......

Took two seconds to find "these stupid stuff ". I didn't write it, apparently the guy who posted it took it straight from some sort of Mazda training manual so it's not just useless info posted by some retard on a forum. Oh, but I forgot, your the expert. Maybe they should hire you to write service manuals then huh? Hilarious.

Guys, why can't we all be friends!!
After all, at the end of this thread, whenever that is.... people will use synthetic oil if they want to, others will use dino oil if they want to... and either one will use them according to their own experience and believes.
Happy driving everybody!
