The classic Z23 Spin-On Oil Filter is back

Ryco Filters says British classic car enthusiasts will rejoice to hear that it has re-released the classic Z23 Spin-On Oil Filter.
First released in the 1960s, the Z23 spin on filter with the unique ½ inch BSPF (½ -14 BSPF) thread size will be released this year after a more than decade on hiatus.
“Owners of classic British vehicles no longer have to make do with oil filter conversion kits,” Ryco Filters General Manager of Engineering and Innovation, Alastair Hampton, said.
“The brand new Z23 is better than OE, utilising 21st century filter media and presented with a nod to its historic past with retro touches. We wanted it to look like the original Z23s once in the engine bay.”
The Z23 features a unique thread size, the only one in the Ryco range and used on BMC engines of the period. Also featured are an anti-drain back valve with a stack tube to support an inverted mounting position; a pressure relief valve making it a modern OEM quality filter; and media and construction with superior efficiency, life and flow of the original Z23 oil filter.
The filter fits uniquely British vehicles utilising engines from the BMC B-Series family of four cylinder and six cylinder engines. British classics such as: Morris Major and Elite, Oxford, Austin 1800, Lancer, A40, A50, A55, A60 Cambridge, Freeway, Wolseley 24/80, 1500, 15/50, 15/60, 16/60, 24/80, MGA, MGB (1955 – 1974), MG Magnette ZA, ZB, Mk3 – 4, Riley one point five, 4/68, 4/72 and Leyland Marina 6.
The Z23 can be easily fitted or removed with the RST222 Spin On Filter Cup made especially for unique Ryco filters cans, with a 92 mm diameter can with eight flutes.
“The vintage appearance of the filter was researched by the Engineering team digging through the Ryco Filter archive and uncovering original samples to come up with the original can colour, retro screen print and retro style packaging for a more correct period appearance for the filter in the engine bay, and more authentically pleasing for the classic car owner,” Alastair said.
The original dark grey colour of the filter cans was commonly referred to on the Ryco factory floor in Maribrynong as ‘Battleship Grey.’ The paint was excess dark grey battleship paint purchased post WWII by Ryco from the ship building yards in Williamstown in Victoria. After that supply of paint ran out the filter cans continued to have varying shades of grey throughout the 50s, 60s and 70s until paint colours were fully standardised.
“We’ve already had people contact us to say that they were just about out of their stash of Z23s purchased more than a decade ago, so the timing of the re-release is a relief for some owners,” Alastair said.
The Z23 is available from all good Ryco stockists from July 2020.
“If it’s not on the shelf at one of our distributor’s stores you can ask them to order in for you, or purchase through their online websites,” Ryco Filters Marketing Manager, Melissa Simpson, said.
