I use Pennzoil Platinum Euro Full Synthetic 5W-40 in my Fiat 124 Spider, and it’s been great so far. The engine runs smooth and quiet, and cold starts feel solid. No issues with oil consumption, and it holds up well between changes. The 6-pack of 1-quart bottles is convenient and makes it easy to measure out exactly what I need. Overall, it’s a quality synthetic oil at a good value. I’ll keep using it in my 124 Spider.

OEM quality and perfect fit with no leaks

Size: 1 Count

This is the real deal for anyone wanting to stick with OEM parts for their Chrysler or Dodge vehicle. The filter arrived sealed and well-packaged, and installation was quick with no surprises. This fits my 2016 Chrysler 300 sedan. It fits perfectly and performs just like the one from the dealership but without the inflated price. There were no leaks, and oil pressure stayed consistent post-change. If you're doing your own oil changes, it’s worth sticking with a filter that’s built specifically for your engine - this one does the job right. Pros: True OEM fit and function Well-sealed and clean install Performs reliably Tip: Pre-fill the filter with oil before installation to reduce dry start wear and improve circulation right away.
