When you can’t afford, or can’t find a decent RX-7, you know you can always rely on an RX-8. As a former RX-8 owner myself, my advice is to remember these things before buying!

7 Things You Need To Know Before Buying A Mazda RX-8

1. They must be kept above 3000rpm

This is an absolute must. If you plan on buying a used rotary make sure you quiz the previous owner about their compulsory attention to this fact as, by doing so, it minimises carbon build up. And while you’re at it, make sure you redline your RX-8 at least once a day - not that this is a difficult task to follow…

2. Passengers over six-feet can sit in the rear

This tip goes against logic, but if you have a passenger who is over six-feet tall they will feel more comfortable in your back seat. Trust me. So if it’s practicality that’s putting you off buying an RX-8, remember, they’re more functional in the real world than you might think.

3. The engine floods easily

The flooding will be caused due to a cold start and immediate shutdown on most occasions. Make sure you let her warm up and cool down properly every time you drive. The flooding is actually caused by too much fuel left over from the choke still being on when the car is shut off, and then being on again when you start it the next time.

4. Engine life can be short

Due to the high-revving nature of the RX-8’s Wankel engine, everything rubs together a lot more and ends up wearing out quicker. Making it to 65,000 miles is sometimes a challenge with the rotaries. Start saving now as engines cost anywhere from £1600 ($2500) and up.

5. Apex seals are the first part to fail

As most of you will know, the apex seals are usually the first part of the engine to fail. If you imagine the Wankel engine as giant, spinning Doritos you will find these seals at the apex, or peak of each of them. They are the only part that comes in direct contact with the rotary housing, hence their fragility. Apex seals alone cost around £224 ($350) so plan ahead for labour.

6. Be prepared to replace coils often

The ignition coils are essential to ensuring that your RX-8 is properly powered. Everyone replaces their coils at different times, but a good rule of thumb is to start checking them at least every 30,000 miles. For a set of ignition coils you’re looking at £70 ($110).
