SC Rotary Engine for Me:-{

I love my 2005 Mazda RX8...I really do. I have had it since last July. Unfortunately, do not like this rotary engine. Of course the dealer want to wipe me clean for a trade in for a traditional engine. My neighbor stated there are clubs really are into these cars I can understand why, just wish this starting up stuff is for the birds....Any suggestions?

Welcome.
Read the new owner stickies.
Meanwhile, what start up stuff are you talking about?

Op,

Your post made no sense. Read the threads within my SIG below. Pay close attention to new and potential owners thread.

Are you having starting issues?

Mileage? What were the numbers of your last compression test?

Snake... you are precisely the kind of owner we fight against on here. You are spreading ALL SORTS of misinformation about this car, and causing more problems than you are solving.

The RX-8 is indeed just a car you can start up and drive. The caution is against HARD driving. Keep the revs lower and avoid full throttle to let the fluid temps come up before romping on it.

Piston engined cars are no different. You shouldn't romp on a cold piston engine either.

You can shut off the RX-8 cold. If your compression, ignition, battery, and starter are all healthy (Which they should be if you are taking care of the car), you will never flood an RX-8 shutting it off cold. IF you neglect your car, then shutting it off cold puts you at risk of flooding. Pick one: You neglect your car and insist it has to be shut off warm, or you take care of your car and can shut it off whenever you want.

Synthetic oil is just fine in the rotary. There is only ONE failure method where synthetic vs dino makes a difference, and it is insanely rare: e-shaft bearing failure. "Synthetic buildup on the seals" is literal crap. Synthetic oil cleans the seals same as dino. All the buildup is from the GASOLINE. Seal failure is not affected by which type or weight of oil you use.

Um, there is a complicated and expensive oil injection system designed to deliberately inject oil into the engine. How exactly do you think synthetic oil disables this system? It doesn't. It can't. In fact, dino oil would clog the OMP lines well before synthetic oil would, which is the only possible way that it would be affected.

No it didn't.

Probably because he was neglecting the ignition, which needs changing every 30,000 miles at least. Plugs and wires people know about, coils, many people don't.

Again, it's that deliberate injection system.

It's not. Starting difficulties are always due to a failure in one or more of: Compression, spark plugs, plug wires, ignition coils, battery, or starter. If those are healthy, the RX-8 will start fast and easily every time.





Every single one of these points well covered in the https://www.rx8club.com/new-member-f...t-here-202454/ thread, which is something that people point new owners to worldwide (I can see all the tracebacks). You would do well to re-read it carefully.

Seems I've been missinformed by a Mazda tech. (Not everyone including a tech is always honest or know what they are talking about). Thanks for the infoinformation. I'm on the read now.

Yes, Mazda techs are just as damaging to the rotary's reputation. Most of them have no clue either.

Thanks. This info I was wrongfully given could have destroyed my own car. This is a long read but very informative. Thanks again

Very true.
If I had not discovered this forum after I bought mine almost 3 years ago, I'm sure I would have needed a rebuild by now and ended up hating it.
Now I love it thanks to all the help I've received on this forum, especially from RIWWP.
I was lucky that I was not afraid to ask 'dumb' questions, and I asked a lot of them.
I learned a great deal here, and am still learning.
Always come here first for answers, and don't hesitate to ask for help.

If you really are afraid of being Flamed with a dumb question, PM someone.

Good advice to pm sometimes, I do. Also there is a dumb question thread you can use anytime.
