LIQUI MOLY Launches New Motor Oil for Stellantis Models

May 30, 2025
The new product—Top Tec 6320 5W-30—is intended for engine types that require a lubricant with the specification Stellantis FPW9.55535/03 or PSA B71 2290, PSA B71 2297, as well as ACEA C3 and API SP.

LIQUI MOLY has released a new motor oil to accommodate the latest standard for PSA engines, Stellantis FPW9.55535/03.

As shared in a recent press release, the new product—Top Tec 6320 5W-30—is intended for engine types that require a lubricant with the specification Stellantis FPW9.55535/03 or PSA B71 2290, PSA B71 2297, as well as ACEA C3 and API SP.

The new engine oil can be used for EB2 gasoline engines and for DV5R, DW10F, and DW12R diesel engines built from 2012 onwards.

As noted by Reiner Schönfelder, application engineer in LIQUI MOLY’s research and development department, these engines often feature a toothed belt that runs in oil, leading to greater abrasion and wear. The new low-ash, low-friction motor oil aims to protect the engine from wear and soot deposits. It’s also designed to prevent the low-speed pre-ignition that sometimes occurs in modern downsized gasoline engines with direct injection.

“We are adding Top Tec 6320 5W-30 to our existing range for Stellantis Group brands to offer the right oil for every vehicle,” said Schönfelder.
