Adds 1 litre of oil capacity and integrated cooling fins to keep the Renesis lubricated and cooler under hard driving.

Just put my Greddy oil pan on this past week and switched from Royal Purple 5w20 to 5w30. On driving back & looking at my EGT's it is a good 30-40 degrees F cooler than before. Didn't think it would make much/if any difference, but it did. I'm pretty surprised, I guess the extra .5 Quart of oil and/or the aluminum design makes a bit of difference.

This RX8 large capacity oil pan is a direct-fit sump upgrade for Series 1 Renesis engines. It solves two known weaknesses in one part: oil starvation under sustained high-G loads, and chronic heat build-up at the sump.
Capacity increases by approximately 1 litre. That larger reserve keeps oil at the pickup when cornering forces push it away from the centre.
Integrated cooling fins on the pan body stabilise oil temperature passively. GREDDY TRUST designed this as a genuine alternative to fitting a second oil cooler. This is particularly useful on cars running only one cooler already. The pan is also reinforced to increase overall engine rigidity.
Mounting accuracy and hardware quality exceed the original Mazda unit. A dedicated 1/8PT port accepts an oil temperature sensor for direct sump monitoring. The shape preserves full access for engine removal and refit.
For RX8 enthusiasts pushing their Series 1 hard, this pan earns its place as the most impactful sump upgrade available. Heat comes down, oil supply stays consistent, and the engine carries noticeably more resilience through sustained demand.
Pair this pan with the GREDDY TRUST Super Magnetic Oil Pan Sump Plug, which threads directly into this pan and captures metallic wear particles at every drain. The GREDDY TRUST Oil Filter completes the oil system refresh at the filter end, keeping the RX8 large capacity oil pan working with equally matched filtration. For cooling support on the water side, the R-MAGIC Super High Flow Water Pump keeps coolant circulating efficiently under sustained load.

The GREDDY TRUST large capacity oil pan is built specifically for Series 1 RX8 models produced from 2003 to 2008. It is not listed as compatible with Series 2 RX8s, so confirm your build year before ordering.
During sustained high-G cornering, oil can be pushed away from the pickup in a standard pan, starving the engine momentarily. A deep sump increases the total oil reserve the lubrication system draws from, making repeated hard corners and back-to-back laps a less critical concern for the Renesis rotary.
The GREDDY TRUST large capacity oil pan is designed as a direct replacement for the standard Series 1 RX8 sump. No listed modifications are required for fitment.
The Renesis rotary is known to be sensitive to oil starvation because its lubrication demands are continuous and its oiling geometry differs from a conventional piston engine. Sustained cornering that shifts oil away from the pickup can cause lubrication gaps, making extra oil volume a practical safeguard rather than an optional extra.
The pan has a silver finish that keeps it clean and presentable in the engine bay. The finish also makes visual inspection straightforward during routine servicing, so leaks or contamination are easy to spot at a glance.
Yes. The GREDDY TRUST Super Magnetic Oil Pan Sump Plug fits directly into this pan and captures metallic particles with every drain cycle, adding another layer of protection to the lubrication system alongside the increased oil volume.
This listing covers the Series 1 fitment only, suited to 2003-2008 RX8 models. If you own a Series 2 RX8, check for the corresponding Series 2 variant separately, as the two series have different sump configurations.
