The RX8 oil filter is a routine service item, but the Renesis rewards careful choices here. This GREDDY TRUST unit suits Series 2 models from 2009 to 2012. Its double-pleated filter paper folds more media into the same canister space. That expands the effective filtration area beyond what a standard single-ply element offers. TRUST Japan has backed rotary development with genuine enthusiasm, and that history carries through to even their service-grade components.

GREDDY TRUST RX8 Oil Filter Series 2 Features

  • Series 2 specific fitment threads directly onto the Renesis engine in 2009-2012 RX8 models without any modification.
  • The double-pleated fold expands filtration area by packing more filter media into the canister than a conventional single-ply element allows.
  • Greater media area means the filter traps more contaminants. This delivers longer service life and cleaner oil across the full drain interval.
  • Engineered to maintain consistent oil flow at the elevated temperatures and high revs the Renesis generates in normal use.
  • Finally, the Series 1 equivalent is listed separately. That makes it straightforward to order the correct filter for your generation without cross-referencing part numbers.

For RX8 enthusiasts, oil cleanliness is not a minor concern. The Renesis runs tight apex seal clearances. Degraded or contaminated oil accelerates wear faster than in a comparable piston engine. Choosing a Mazda RX8 oil filter with improved filtration performance is one of the simplest steps toward preserving engine health between services.

Pair this filter with the GREDDY TRUST Super Magnetic Oil Pan Sump Plug, which captures ferrous particles at the drain point before they recirculate. The AUTOEXE x KOYORAD High-Capacity 48mm Aluminium Radiator keeps coolant temperatures lower, reducing the thermal load the oil carries on a warm Australian day.

Owners can explore the full GREDDY TRUST range at the official GREDDY TRUST website. For the Series 1 version of this filter, see the GREDDY TRUST Oil Filter listed separately for that generation.

Frequently Asked Questions

Will this GREDDY TRUST oil filter fit my 2009-2012 RX8?

Yes. This GREDDY TRUST oil filter is designed specifically for Series 2 RX8 models built from 2009 to 2012 and threads directly onto the engine without any modification.

What makes the double-pleated filter paper better than a standard oil filter?

The double-pleated design increases the effective filtration media area compared with a standard single-ply element. More surface area means the filter traps more contaminants across the full service interval, keeping oil cleaner for longer.

Is there a GREDDY TRUST oil filter for Series 1 RX8 models?

Yes. This listing covers Series 2 (2009-2012) only. GREDDY TRUST produce a separate oil filter for Series 1 RX8 models, listed individually on the site.

Why does oil filtration matter more on a rotary engine than a conventional piston engine?

The Renesis runs tight apex seal clearances, so contaminated or degraded oil accelerates internal wear more rapidly than it would in a typical piston engine. Fitting a quality filter at every service interval is one of the most straightforward reliability measures available to RX8 owners.

Can this filter handle the high oil temperatures a rotary engine produces?

Yes. The GREDDY TRUST filter is designed to maintain stable, consistent oil flow at high engine speeds and elevated oil temperatures, which are normal operating conditions for the Renesis.

What other service parts pair well with this oil filter?

The GREDDY TRUST Super Magnetic Oil Pan Sump Plug complements this filter by capturing ferrous particles at the drain point before they can recirculate through the engine. Both can be replaced together as part of a complete Series 2 oil service.

Does GREDDY TRUST have experience with rotary engines specifically?

Yes. GREDDY TRUST have a development background in Japanese rotary motorsport, which informs the engineering standards applied even to routine service components like this oil filter.
