GENUINE MAZDA OEM Floor Mat Set for Mazda RX8 (Series 1 & 2, 2003-2012)
Shout out to RX8 Upgrades for these awesome custom mats easy to deal with and good service
I am happy with the mod. Very happy. Taka s recommended first mod list: Sway bar. Odula intake or similar. Brake pads.
The AutoExe stuff is very nice--the leather is soft and rich, though the stitching isn't perfectly uniform. The AutoExe red stitching is a little brighter than the boot stitching and OEM stitching, but the difference isn't as big as it seems in the pictures. Overall, I'm very happy with this interior refresh. It feels like a new car.
OHLINS MAS-MI00S1 Road & Track Coilover Suspension for Mazda RX8 (Series 1 & 2, 2003-2012)
I use the Ohlins coilovers on my RX8, which is mainly used for street use and I found the standard spring rates to be too soft in the rear but the fronts to be fine. I changed my rear springs to about 350lbs/in and it feels pretty good to me now.
HKS Hi-Power Cat-Back Exhaust with Titanium Tip for Mazda RX8 (Series 1 & 2, 2003-2012)
I say hks hi power (im a happy owner of it)
The rotary engine has lubrication demands that set it apart from a conventional piston motor. For example, the 13B burns a small amount of oil by design. This is part of its apex-seal lubrication system. In addition, it runs at high rpm more freely than almost any production engine ever built. It also generates heat in a combustion chamber geometry unlike anything else on the road.
Therefore, choosing the right Mazda RX8 engine oil is one of the most consequential service decisions an owner makes. It deserves more than a generic pick off a shelf.
Without pistons, a conventional crankshaft or valve train, the 13B relies on oil to protect the eccentric shaft, bearings, rotor housings and apex seals. Moreover, conditions vary enormously between a cold street commute and a hard track session. An oil that is too heavy can starve high-speed components at operating temperature. Meanwhile, one that is too thin offers insufficient film strength under sustained load.
The 13B’s tolerances and thermal behaviour differ fundamentally from the cars most general service guides are written for. As a result, RX8 engine oil selection matters in ways it simply does not for a conventional motor.
Getting the right product to your door without compromise on quality matters as much as the oil choice itself. However, quality is only part of the equation. Each product in this range is listed with the details you need to confirm suitability before you order. Therefore, cross-reference with your service history, current engine condition, and any specialist advice specific to your build stage or mileage.
For factory lubrication specifications, Mazda Australia publishes owner resources and service guidance for your vehicle. Because the rotary rewards consistent, attentive servicing, it all starts with getting Mazda RX8 engine oil right.
If you are planning a broader service or refresh, the lubrication products here pair naturally with other maintenance items across our range. In addition, keeping oil-related consumables current is the foundation everything else is built on.
The RX8's rotary engine has different lubrication demands to a conventional piston engine. Mazda specifies an oil grade and type in the owner's documentation, and that guidance is the correct starting point. Oil condition, service history and how the car is used can all influence the best choice for a given vehicle.
Not all oils marketed for general use are appropriate for the rotary engine. The Renesis engine uses oil differently to a piston engine, including burning a small amount of oil as part of its normal operation, so viscosity grade and formulation both matter. Always cross-check the product details against Mazda's owner documentation before purchasing.
Mazda's service schedule sets the baseline interval, but many RX8 owners service their oil more frequently given the rotary engine's operating characteristics and its sensitivity to oil quality. The car's condition, use, and whether it sees track or hard street driving are all worth factoring into your service plan.
Yes. The Renesis rotary engine burns a small amount of oil as part of its normal operation, used to lubricate the apex seals. Checking the oil level between services is standard practice for RX8 ownership, and topping up with a compatible oil is part of routine maintenance.
A complete lubrication service typically involves engine oil and an oil filter as a minimum. Depending on the service scope and the car's condition, additional oil-related items may be required. Reviewing each product's details against your planned service work helps confirm you have the right items before starting.
Track use places greater thermal and mechanical demands on engine oil, which can shorten effective service life compared with standard road use. Reviewing product specifications carefully and consulting Mazda's guidance is the right approach; some owners running their RX8 hard choose to reduce service intervals alongside any oil selection decision.
Mixing oils of different grades or formulations is generally not recommended. If a top-up is needed between services, using the same oil already in the engine is the preferred approach. If that is not available, confirming compatibility with the existing oil's specification before adding anything is worthwhile.
